Yes - it's rare for Blu-rays. But common for FLAC files. I just purchased the Jurassic Park original motion picture soundtrack - a 192kHz, 24 bit encoding - from the usual place - www.hdtracks.com

From what I've read in the manual, any updates needed will immediately show on the 8801 front monitor.

From the Setup Menu: General --> Firmware --> Update -> Check for Update

If the result has a line that says "Update Firmware Latest", then you already have the latest update.

Because the acoustic limitations of your listening room have less effect when the sound is coming out of two speakers instead of five?

The first assumption in that discussion is that you are trying to listen to ultra-high definition stereo music.

So why did I suggest using "Audyssey Byp. L/R"? Because the theory (or recent discovery) is that turning on Audyssey reduces the sound quality of high-res music. I think they said down to 48 kHz? Need to go back a few pages in this thread and check again.

Here it is - read this post -

Anyway - my point was - if that's the case:

1) if Audyssey has to down-sample to 48kHz in order to apply Audyssey filters,

2) and if I want to actually play my 96kHz and 192kHz music in true 96kHz or 192kHz form -

Then it's necessary to bypass Audyssey. And many (or at least some) listeners on this thread enjoy stereo playback with Audyssey turned off.

Don't you go bringing scientific facts into this discussion. My mind's already made up!

Actually - I haven't made up my mind yet. Interesting article. I've bought a small collection of 24 bit/192 kHz music. Some of it overlaps my CD and SACD collection. But I've done very little listening and no A/B comparisons. I think I'll compare my latest 192kHz/24-bit purchase (Jurassic Park) to the plain old CD soon.

Thanks for the link. Very interesting, technical, detailed reading...

I'm waiting for his Pono music download site also. I hope there will be some newer high res music available in my preferred genre's. Although I've heard some 16 bit music sound better than some 24 bit, it all comes down to how well it was mastered.

As far as hdtracks.com goes it's a crap shoot some sound good and others not so good. Again being well mastered is the key. A saying came to mind, "you can't shine $hit" biggrin.gif

Guys,
What power amp are you using with your AV8801?
Thinking of partnering mine when I get hold of it with NAD T975...
Anyone of you using the same?
Thanks smile.gif

How do you like the new M2 D Sonics compared to some of the other amps you've used, and what speakers do you have?
a1usedcomp's Avatar a1usedcomp 08:02 AM 04-13-2013
My current speakers are Salk Songs RT - Salk Song Center RT - Selah Surrounds

I owned Theta which I really liked , I also owned Emotiva amps I like the D Sonic over the emotive that's for sure and the theta was to long ago

D Sonic is dead silent and since its class D it runs very cool

Those are nice speakers. I bought my Revel fronts from Mr. Deacon a couple months ago. How is the bottom end in your Salk's with the D Sonic? I'm considering buying a couple of his monos.

I forgot I had that amp also but only for a week it came in a package deal when I bought my Kef Model Fours which I ended up shipping the speakers to Alaska I sure miss those speakers

I ordered some bulbs for the amp from Sunfire but they never showed up

I wouldn't mind trying one with my speakers , in about 3-4 yrs I'm going to have Salk or Selah build me some real nice speakers

It's a good amp, mines worked flawless for over 7 years. But it's time for a change. Have a good day.

The MM8807 is a nice amp, which you can get at a discount when purchasing the AV8801. I have the MM8807 coupled with the Parasound A51.

With 2 passive subs and a Tactile transducer, can I make use of the balanced sub pre-out as a third sub output for my transducer? I wasn't sure if the balanced and none balanced pre-outs are active at the same time.

Has anybody had luck downloading the AV8801 Manual in pdf from the Marantz website?

I have been trying to find the manual not the getting started pdf with no luck.


UPDATE, finally got it to work after this posting, go figure.

Anybody experienced that the AV8801 suddenly turns off, than on again?

Was watching "Iron Man 2", and it happened 3 times. The first time I thought it was a power grid problem, but I started to doubt that when it happened a second time. Because the power here is very stable.
And it happening 3 times within 2 hours makes me believe theres something wrong with the AV8801.

Both my TV and PC didn't turn of, only the AV8801. I have had it since early february, and it have never happened before. Upgraded to the latest firmware last weekend, and have watched both movies and other things after that without problems.

I also touched the sides of the AV8801, and it was cold as it should be. I have 2 fans blowing on it from behind since it's in a tight space, my last AV8003 got hot when the fans wasn't on.

After playing around with AV8801 various modes, my search for a separate 2 channel preamp has just ended. I'm completely satisfied with its 7.1 analog input section for playing 2-channel music. Based on my observations, I'm getting very dynamic sound, with pristine highs and without any hint of sounding thin or sterile in the midrange area. The analog section is very... very good and will resolve good or bad upstream electronics. So, if the music sounds bright or thin, try changing out the CD player or DAC to fine tune the sound to your liking.

My expectations were too high with Classe CP-800 analog preamp and it didn't blow me away. So, I've ended my search for an analog 2-channel preamp and decided to use AV8801 instead.

Thrang, if you're reading this... are you missing your Classe CP-800 preamp?

I can't decide whether to get the MM8077 and MM7025 power amps or 2 units of MM7055 power amp to power my 9-channels. The AV8801 and 2xMM7055 combo is cheaper by around $560. Will there be a significant difference in sound quality between the MM8077 and MM7055? Thanks!!! smile.gif

For the money the Marantz amps put out relatively little power. Roughly 100 watts all channels driven. You may want to look for a better amp for the $$ (ATI, Outlaw, etc.). You could literally double your power for the same amount of money.

The balanced and non balanced pre-outs are active simultaneously. This is something I needed as well, but in my situation my 2 subwoofers are connected via the balanced XLR's. So I needed to use one of the non balanced sub pre-outs to connect to my transducer power amp. It works great!

The only thing to note is that the LFE output on the pre-outs are shared, meaning that the level setting you use on one output (in my case XLR) also affects the output setting on the other one (RCA). So if you don't have enough of a bass effect with your tactile transducers when you connect it, this is why.

According to this review published yesterday on Anthem's Room Correction system (ARC) by Dr. David A. Rich on Secrets of Home Theater and High Fidelity's website, the AV8801 down-samples high-resolution signals to 48KHz/sec when applying Audyssey MultEQ XT32.

Read the following quote taken from the review on the referenced website link:

"Notes on High Resolution Signal Processing:

The Anthem D2 and AVM Pre/Pro products that have ARC will process an incoming signal at its native rate up to 96k samples/second. Robert Kozel verified this by using a 30kHz test signal sampled at 96k samples/sec on an Anthem D2. He did the same test with the new Marantz AV8801 Pre/Pro that has Audyssey MultEQ XT32 room correction. The AV8801 did not pass the 30kHz signal because it down-sampled the high resolution test tone to the standard resolution of 48k samples/sec. The Marantz AV8801 is $3600 before the costs of having the unit upgraded by a Marantz certified Pro Installer using the Audyssey PC based tools and calibrated microphone. Sampling at 96k sample/sec requires twice the DSP resources for the real time filters used for room correction.


The Marantz AV8801 has three 4th generation Analog Devices ADSP21487 DSPs which provides as much digital signal processing capability as found in any Pre/Pro using Audyssey MultEQ XT or XT32 room correction that I know of. I expect many and perhaps all Audyssey MultEQ XT or XT32 enabled products, including those at higher price points, will also down-sample high-resolution material to 48k samples/sec when the room correction is enabled. The Sherwood R-972 with Trinnov also down-sampled high resolution material to 48k samples/sec.


Anthem’s lower cost MRX AVRs do down-sample to 48k Samples/Sec."


If this claim is accurate, this is not encouraging news for HD music aficionados, myself included. Does anyone with deep knowledge of the AV8801 or the Denon AVR-4520CI sister platform have any insights on this issue?

Audyssey's dirty little secret! Not many people know that Audyssey down-samples hi-bit signals.
