BTW: Acurus just upgraded the Firmware for the MUSE to 2.4 - giving full speaker setup with delays and trims now via the HTML interface. Yay!

Regarding Reference Level on the Muse - I am told by Acurus "We recommend calibrating reference level at 71 – 73 volume level."

Regarding the built in Shelving EQ - I am told by Acurus "The shelving EQ has roll-off that are first order in order to create an approximation of a room curve or simply be used to create compensation for things such as screen loss. You can adjust the frequencies for both the low and high shelf across the entire band."

This is all really good news. The more I listen to the MUSE the more I fall in love with it. Its a pure joy to operate, but even more importantly its one of the best sounding surround processors I have ever heard at any price.

Ill preface this by adding that I spent 20 years in the AV industry in home cinema design. So I do know more than enough to be a little dangerous....

Lets get the bad / niggles out of the way first:

1. Throw the remote in the bin. It’s rubbish. Probably a cold war relic from the 70’s… ok.. most people wont use it, so its ok, but my wife likes a remote (she hates universal remotes - go figure, and a web interface to her is what a star trek teleport is to a cave man - unintelligible). You can argue the remote does what its supposed to, but for a processor that costs around $6k USD I think a better remote would have been nice. Heck, even if I had to pay extra for it I would likely buy it. All of that said.. for me I really like the web interface for control.

2. Where is the Mic Calibration Kit?

3. The manual is almost as useless as the remote. Now thankfully set up is really VERY intuitive and anyone with basic Home Cinema experience can probably do it without a manual (I did). But I did look to the manual for details regarding PEQ setup - but there is ZERO information in the manual on how to do this outside of very basic information on what the PEQ 'is'.. so I haven’t touched it. See point 2 - Where is the Mic Kit? Id also like to understand what the high and low frequency cut offs in the set up menu are supposed to do (not covered in the manual at all)….Are these roll offs to emulate a THX curve for example?

4. Whats with the volume control running from 0 to 95? Where is reference level? Nothing in the manual at all about this… so I had to guess that the unit has around 10-15DB headroom over reference and reference was therefore somewhere around ’80’. So thats what I used to calibrate it to 75DBC weighted with pink noise. I couldn’t take it any further than this (other than setting the obvious like cross overs) since I have no mic kit.. see point 2 - Where is the Mic Kit? Yes, you could calibrate it with REW, but I don't have that at present.

5. I could not set time delays accurately (I did it by ear) since I have no Mic Kit….. are we seeing a theme here?

6. Lastly on the ‘bad, or rather room for improvement front’ the web interface for control is very nice (love it actually) - but why cant I access the setup screen from the HTML interface? Its a pain to have to keep getting up to the touch panel on the muse in the rack every time you want to make a set up change. Also, the HTML interface needs a ‘Home’ button, so you can navigate off the setup screen on the unit back to the main screen when playing content. Id also like the ability to custom name the various inputs since my wife does not understand that i/o1 = Blue Ray (no matter how many times I will tell her this).

Ok.. thats out of the way lets talk about the good (because its very, very good).

1. Sound Quality is really beautiful. Even right out of the box at defaults this things sounds gorgeous. Its very neutral, very smooth, and detail is extremely well articulated (really startlingly so). I wouldn’t describe it as forward, or reserved, but rather just very neutral with a soundstage that is neither in my face nor hidden behind a veil. It reminds me of the Cary Cinema 12 sound or a Theta Casablanca, but its even better for multi-channel than the Cary Cinema 12 (noticeably) - but im not yet sure on high rez analog audio. It might just edge out the Cary in this area as well. I cant remember the Theta well enough, but its similar. Perhaps the biggest thing I noticed after how smooth it is (by comparison the Marantz 8802A is grainy and thin sounding by comparison), was how well it renders subtle detail in movies. It does just a much better job than the Marantz 8802A (which is no slouch for the money) and renders fine detail sound that I was not previously hearing - not only that, but it presents the sounds hanging in space so beautifully and realistically that I was left a bit gob smacked and ended up watching scene after scene from my favourite movies after set up and tweaking. I really am very impressed at just how well it does this. Im not sure if its the inky black noise floor or the chipset, or both - but Wow. Its beautiful. Frankly, its STUNNING. Well done!

2. Set up - PEQ’s, poor manual and lack of mic kit aside - its EXCELLENT. Intuitive, easy and frankly an absolute joy. More manufacturers should check this out as I think its the best I have ever seen (by a long way). Slaughters the Marantz 8802A for setup, and that is not a difficult unit to set up.

3. Build Quality. Stunning. Love it. Touch screen is just gorgeous. With that gorgeous full color touch screen its one of those audio boxes you just want to sit and look at.

4. HDMI switching is quick and seamless. Better even than the Marantz 8802A. Again I am extremely impressed. No issues with Standard Def, Blue Ray, 4K DVD or Apple TV. All worked out of the box. Using Fibre cable to the BenQ W11000H 4k Projector.

5. Loved the capability to set Trigger 1 and Trigger 2 on different delays since turning on two big Cary Cinema 5 power amps will occasionally throw the safety switch in my house. Someone really thought this one through and I really appreciate it.

6. Inclusion of a customisable Night mode was good thinking. This will work well for my family.

Overall - Im VERY impressed. If the mic kit and calibration matches up its going to be pretty unbeatable for the money. Im told late June for a mic kit.. we shall see...

My system:
BenQ W11000H 4 Projector
Screen Research 4K Screen
Acurus Muse 16 Channel Processor
2 x Cary Cinema 5 Power Amplifiers
M&K S300 MKII THX Speaker System with 2 X12 Subwooers
4 x Triad In ceiling Bronze Dolby Atmos speakers
Wired with AudioQuest King Cobra and CV-4 PSC+ Speaker Cable
A Bunch of power conditioners etc.
Room was custom designed, dedicated and acoustically treated with absorption, diffusion and multiple bass traps.

How many independent sub out channels can you set? Can Acurus do 7.4.4 channels with 4 independent sub outs?

Thanks. Looks like it can do up to 3 independent subs which should be enough for most people. It looks very nice and interesting. Not sure how good ASPEQT is as compared to Dirac or ARC. The lack of inexpensive mic kit to run room correction by yourself has turned me off. I am waiting for ATI and Monoprice processors to come out later this year before pulling the trigger.

No one is sure about ASPEQT as the mic kit is not yet available. The fact its inexpensive when it its released is a plus to me. I dont want a cheap mic kit full of errors. I want a precision instrument that gives me accurate and reliable readings. The mic kit is one place eI definitely dont want them to skimp on. Just my two cents...

You’re aware that, as things now stand, the mic kit will list for ~$2,500?

I think the kit is designed for installers and calibrators amd not the end user.

Yes. Are you aware it comes with four calibrated precision microphones and a multiplexer? That makes $2500 more than fair.

I understand that’s the plan, yes, but even a casual reading about owners of other, similar high-end products will show that the vast majority end up wanting to do their own tweaking, and that involves actually owning the kit.

I’m not sure potential buyers, as a whole, would agree with you, but everyone’s MMV, as always.

It really depends on how good the performance is of ASPEQT. If it's good competition quality wise to DIRAC or AUDYSSEY with a pro kit then it will sell well - especially to those who wish to tinker.

So basically you are paying $2500 to use the Room Correction on a $5500 processor.

Thats true - although lets be honest, the two are independent and not really related outside of the fact that some people dont like the price of one or the other. Just because a processor might cost more than $20k doesn't mean its room correction hardware should cost $5k and vice versa. Whats important is that the room correction hardware is calibrated and is providing reliable and repeatable results. If that means its a 4-mic kit with a multiplexer that is going to cost $2500 so be it. Id rather that than a plastic cheap microphone..... The software - well that needs to be as good as DIRAC or Audyssey.

As mentioned above too - I think the calibration kit is really aimed at installers who are going to do a lot of these. For the tinkerer, yes, its a significant outlay to purchase a mic kit, but for most tinkerers I think it will be worth it since tinkerers are about extracting every possible drop of quality out of a system.

Of course, the other option is dont purchase the ASPEQT kit if you think its too expensive. Use Room EQ wizard. There are options in todays market :-)

Unless it includes 4 Trinnov tetrahedron mics that only cost $700, $2500 for their room correction kit is ridiculous.

Not only that, it's just measuring the frequency response and the results will be smoothed, so anything more than a calibrated $100 mic is wasted. They probably use the same capsules as the "cheap" mics like the Umik-1.

The bottomline is that expensive mics aren't needed for room correction. Even cheap mics perform very well where it matters, in the lower frequencies. No RC system worth its salt is going to be making large corrections above 10kHz, which is where the expensive mics are more accurate.

And why do you need 4 mics? You could just move one microphone around the room. There are not many benefits other than saving a bit of time.

Can you elaborate on that?

Neural X with wides is limited to 11 ch, i.e. 5+W.x.4; can the Muse do 7+W.x.4 with matrixed wides?

Im afraid I can't. I just lifted that text from the firmware upgrade notes. There was no further detail provided and in my own set up I dont run wide channels.

So still no mic kit available?

Also, does the muse have ARC for TV sound via HDMI?

There's no mention of it in the manual.

In my (limited) experience, HDMI inputs which support ARC are marked as such, but on the Muse back panel they all look the same.

I believe that since it is ACT4 clone and ACT 4 targeted HT instalators market they did not think of ARC as priority. You don't need it if you watch movies in 200" screen. I hope, however, that in case of Muse they will add it sooner or later since Muse targets end users that would connect it directly to TV (my case).

Agree with all the pros and cons that were posted here. Just adding what I have found out: playing old DTS or DolbyHD movies (both DVDs and BR) I noticed a short (less thne 1s) audio drop after ca. 90 min playback. The was vastly descriced on Emotiva RMC-1 forum, so probably no need to describe it but I am wondering if anyone else noticed that. It's not very annoying since while playing the movie at home there is always a need for pause and therefore reseting the clock but, in my opinion, this should be fixed.


And one more thing: where to find the new firmware for Muse? I searched the Acurus.com website and either I can't find the obvious link or it's really secret place? I was asking about that Acurus support when trying to register Muse at the time when there was Muse listed in product registration page (they added Muse imediately), but after 6 weeks no anser to my question. Also, the manual does not mention firware uddate procedure...

Heck, even if I had to pay extra for it I would likely buy it. All of that said.. for me I really like the web interface for control.

2. Where is the Mic Calibration Kit?

3. The manual is almost as useless as the remote. Now thankfully set up is really VERY intuitive and anyone with basic Home Cinema experience can probably do it without a manual (I did). But I did look to the manual for details regarding PEQ setup - but there is ZERO information in the manual on how to do this outside of very basic information on what the PEQ 'is'.. so I haven’t touched it. See point 2 - Where is the Mic Kit? Id also like to understand what the high and low frequency cut offs in the set up menu are supposed to do (not covered in the manual at all)….Are these roll offs to emulate a THX curve for example?

4. Whats with the volume control running from 0 to 95? Where is reference level? Nothing in the manual at all about this… so I had to guess that the unit has around 10-15DB headroom over reference and reference was therefore somewhere around ’80’. So thats what I used to calibrate it to 75DBC weighted with pink noise. I couldn’t take it any further than this (other than setting the obvious like cross overs) since I have no mic kit.. see point 2 - Where is the Mic Kit? Yes, you could calibrate it with REW, but I don't have that at present.

5. I could not set time delays accurately (I did it by ear) since I have no Mic Kit….. are we seeing a theme here?

6. Lastly on the ‘bad, or rather room for improvement front’ the web interface for control is very nice (love it actually) - but why cant I access the setup screen from the HTML interface? Its a pain to have to keep getting up to the touch panel on the muse in the rack every time you want to make a set up change. Also, the HTML interface needs a ‘Home’ button, so you can navigate off the setup screen on the unit back to the main screen when playing content. Id also like the ability to custom name the various inputs since my wife does not understand that i/o1 = Blue Ray (no matter how many times I will tell her this).

Ok.. thats out of the way lets talk about the good (because its very, very good).

1. Sound Quality is really beautiful. Even right out of the box at defaults this things sounds gorgeous. Its very neutral, very smooth, and detail is extremely well articulated (really startlingly so). I wouldn’t describe it as forward, or reserved, but rather just very neutral with a soundstage that is neither in my face nor hidden behind a veil. It reminds me of the Cary Cinema 12 sound or a Theta Casablanca, but its even better for multi-channel than the Cary Cinema 12 (noticeably) - but im not yet sure on high rez analog audio. It might just edge out the Cary in this area as well. I cant remember the Theta well enough, but its similar. Perhaps the biggest thing I noticed after how smooth it is (by comparison the Marantz 8802A is grainy and thin sounding by comparison), was how well it renders subtle detail in movies. It does just a much better job than the Marantz 8802A (which is no slouch for the money) and renders fine detail sound that I was not previously hearing - not only that, but it presents the sounds hanging in space so beautifully and realistically that I was left a bit gob smacked and ended up watching scene after scene from my favourite movies after set up and tweaking. I really am very impressed at just how well it does this. Im not sure if its the inky black noise floor or the chipset, or both - but Wow. Its beautiful. Frankly, its STUNNING. Well done!

2. Set up - PEQ’s, poor manual and lack of mic kit aside - its EXCELLENT. Intuitive, easy and frankly an absolute joy. More manufacturers should check this out as I think its the best I have ever seen (by a long way). Slaughters the Marantz 8802A for setup, and that is not a difficult unit to set up.

3. Build Quality. Stunning. Love it. Touch screen is just gorgeous. With that gorgeous full color touch screen its one of those audio boxes you just want to sit and look at.

4. HDMI switching is quick and seamless. Better even than the Marantz 8802A. Again I am extremely impressed. No issues with Standard Def, Blue Ray, 4K DVD or Apple TV. All worked out of the box. Using Fibre cable to the BenQ W11000H 4k Projector.

5. Loved the capability to set Trigger 1 and Trigger 2 on different delays since turning on two big Cary Cinema 5 power amps will occasionally throw the safety switch in my house. Someone really thought this one through and I really appreciate it.

6. Inclusion of a customisable Night mode was good thinking. This will work well for my family.

Overall - Im VERY impressed. If the mic kit and calibration matches up its going to be pretty unbeatable for the money. Im told late June for a mic kit.. we shall see...

My system:
BenQ W11000H 4 Projector
Screen Research 4K Screen
Acurus Muse 16 Channel Processor
2 x Cary Cinema 5 Power Amplifiers
M&K S300 MKII THX Speaker System with 2 X12 Subwooers
4 x Triad In ceiling Bronze Dolby Atmos speakers
Wired with AudioQuest King Cobra and CV-4 PSC+ Speaker Cable
A Bunch of power conditioners etc.
Room was custom designed, dedicated and acoustically treated with absorption, diffusion and multiple bass traps.
Another problem/bug: audio drop after approx. 90 min. of playback of older DVDs or BR disks.


Regarding manual: PEQ is omitted in hard copy included in the box but it is briefly described in manual avalable on their website.


Remote: I am using Harmony remote. I just used ACT4 codes using MyHarmony app - Logitech has full list of RS232 commands but correction for different number of inputs need to be made. Rest is the same. In fact Muse acts as ACT4 clone: when you reconfigure HDMI inputs (2.0/1.4) Muse will reset itself even displaying "ACT4 needs to...". You can also rename inputs in your remote. That was 6 weeks ago so by now Muse can be also listed (have not checked recently).


I am thinnking about some other things I would like to see like support for ARC, DSD decoding or maybe simple player. Unfortunately it looks like this is very minimalistic desing as far as features are concerned (they want it to be true HI-END and distinguish Acurus from Marantz and Emotiva likes). But SQ compensates

Good to know, as I just got an Elite and saw that there's no code support for the Muse.

I'm not clear on what you mean by "correction for different number of inputs need to be made".

Are there discrete commands for each HDMI input?

And one more thing: where to find the new firmware for Muse? I searched the Acurus.com website and either I can't find the obvious link or it's really secret place? I was asking about that Acurus support when trying to register Muse at the time when there was Muse listed in product registration page (they added Muse imediately), but after 6 weeks no anser to my question. Also, the manual does not mention firware uddate procedure...
Regarding Firmware - I get it from Acurus direct as a BETA testa for the unit. I am not sure if I am allowed or supposed to share it. Would recommend you contact them directly.

The update procedure is via Acurus software on a windows PC. It's a bit arduous and time consuming taking around 40 minutes. I am hoping they will push updates in the future. The procedure uses a USB port as a COM port to load the firmware. Its pretty straightforward at the end of the day.

So still no mic kit available?
I am told via email that mic kit is shipping end of June / early July. AS soon as I hav one I will post it up here along with how it all works and results.

Yes, but further explanation is required on set up procedure to make it useful IMO. I am hopeful the mic kit is going to fully automate the set up of Trims, Delays and PEQ's which would mean the manual is currently adequate.

Nothing really special, ACT4 has more inputs, so i13 means for ACT4 second COAX, for Muse 1st analog. For HDMI it does not matters since ther are listed as 1 to 7 for both and both processors have same number of HDMI inputs.

Thanks for replaying about the firmware, so far is not that urgent since my unit works decently, besides the audio drops I described in my previous post and I do not think they can quickly fix this since on Emotiva forum I've read that it looks like this is DSP chip bug.

I don't want to urinate in anyone's pool, but I don't think that ARC can be added via firmware unless the wiring already exists in the unit. As I understand, the ARC pins on an HDMI interface need to be connected to an SP/DIF interface. If said connection isn't made in hardware, no firmware can enable it. I'd expect that if the unit wasn't meant to support ARC, then no connection was made.

It is pretty obvious that if hardware does not support ARC then sofware will not do miracles. But we have right to assume that, when Acurus decided to design Muse (and position it as a competition for Marantz, Emotiva, NAD, Arcam and others in similar price range) made a standard market research what people are using at their homes to watch movies. Most of us have TV's and that means the need for ARC. I cannot imagine that any contemporary project of SSP will miss ARC. It's like designing laptop without webcam. Let's hope that this is also the case of Muse: everyting is there but since they want to release the product as ASAP they skipped many things like any manufacturer of modern electronics. The firmware updates contain not only bug fixes but also new functionalities that were not included/completed when the product was released. Even Trinnov announced thet they are checking ARC feasibility in their SSPs. That would mean that even the company that is not using standard SSP architecture and targets big HT instalations market somehow decided to keep the doors open... I hope that Acurus did it also.
