Well, to be honest, a JBL Synthesis for 6K sounds very reasonable to me. It's like finding a 10K Trinnov

How does this compare to Monolith HTP-1 ignoring the price difference?

The big difference, and the killer feature onthe SDP-55 IMO, is the Logic16 upmixing on the JBL.

Having never owned JBL products before will this come with a remote control since they are targeting the cheaper (if you can call it that) end of the market. I don’t have home automation to link up with it and want to use a standalone remote. Or like the Monoprice HTP-1 no remote?

I did vary the SDA amplifier, pre-amplifier and Processor gain levels to obtain the least idle hiss in my system. I still found it to be annoying.

Are you sure? The difference between BLU-160 and BLU-800 seems to be the additional "Cobranet" digital I/O on the Blu-800. However, the JBL Synthesis page does not show Cobranet I/O in the SDEC-4500 manual.

Do you happen to know if the cards were the same? I believe BSS has shipped a few variants of both the input and output cards.

I hope this statement from Sound & Vision is correct:

Both components are equipped with seven HDMI inputs and support Dolby Vision, HLG, HDR10, and HDR10+ high dynamic range (HDR) formats in addition to supporting HDMI2.0b with HDCP2.2 and 3D video. Further, the HDMI board is removable and replaceable so it can be easily updated to full HDMI 2.1 capability when the format is finalized, ensuring owners aren’t abandoned by a technology upgrade.

The HTP-1 has no remote? That's crazy, I thought the whole idea of that thing was exactly what you are talking about.

There is much info circulating on various threads in regards to Arcam, JBL Synthesis and Audio Control.

I’m trying to weed through it all and get verification.

However there was an earlier question compared to the Monoprice.

The JBL offers Logic 16, Dante networking and Auro (not sure if the HTP1 has this).

The JBL will have the latest DiRac (maybe available on others with firmware update).

Did anyone try the demo at CEDIA? It sounded terrible. Someone in another thread said they were having problems with the processor working correctly (something that is very likely to get worked out). The system sounded very honky, poor midrange, muddy bass. Made it hard to get too excited. It wouldn't turn me off buying this though, because if it was a processor issue it is something they'd obviously figure out before shipping.

Next year is going to be a great year to purchase a Dirac Live processor. For the first time in many years we have a lot of options to choose from, with prices from $4000 to $7000. Particularly the one that caught my attention is the SDP-55 because of Logic16 and Auro as Auro 2D is my favorite music up mixer and Logic7 was my favorite music up mixer in the past. But for those that doesn't care about Logic16 or Dante, then the Arcam AV40 would be the right choice at $4500.

What would you say are the major advantages of Dirac over Audyssey? I finally got a MiniDSP and REW to configure my subwoofers because Audyssey XT32 couldn't manage it.

With music, Dirac Live sounds a bit more natural and less compressed than Audyssey. In the past I hated how Audyssey sounded in my room. That is why I went with the Emotiva XMC-1 with Dirac Live back in May 2017. After the V3 HDMI Board upgrade, the XMC-1 became so glitchy and unreliable that I decided to give it a try again to Audyssey so I got a Denon X6500H for only movies. I kept the XMC-1 for music as to my ears Dirac was superior than Audyssey with music content. With movies, I can live with any of the two. After the last Audyssey Editor app update, without the subwoofer roll off at 20Hz, Audyssey became so close to Dirac that I decided to sell the XMC-1 and keep the Denon X6500H for music and movies. But still, Dirac Live sounds just a bit more natural and less forward than Audyssey. Also, having a trusted and free of issues processor in my system won over the buggy XMC-1. Now that we have a lot more options different than Emotiva, a company that I don't want to deal with ever again, I'm excited again about getting a processor with Dirac Live.

Is Dirac less of a black hole than Audyssey? With REW you can see the resultant response from Audyssey, but Audyssey doesn't show me what filters it is actually putting in place which I don't like. I eventually figured out it was cutting some massive room gain (which I ultimately wanted a lot of) and boosting a null elsewhere that was causing all kinds of headroom issues. When I mimicked the EQing it was trying to do in REW to see what REW said the headroom required would be, it was +10dB. Then after it would ask if you want to turn on DynamicEQ lol, which at the -15 to -10MV level I normally listen at would apply a whole bunch more!

My 7.4.4 Yamaha 3050 setup is very immersive. Not sure if adding front wides and center ceilings would make much difference. I used to have wides with my denon 4311. It was meh. Just some extra ambient noise. The last few channels always cost a fortune.

I suspect in a few years, you'll be able to get an AVR with all these features for under $1k. I can wait.

Well I don't think many people have heard Logic16 yet. However, its predecessor, Logic7 is to my ears the best music upmixer out there. I still have an old Lexicon MC-12 that I use just for logic7 upmixing of music. I think the Dolby surround upmixer for movies is pretty good, but I don't care for it all with most music. DTS upmixing I also like with some movies, though it is more aggressive than Dolby's. DTS upmixing for music is my least favorite. The old Logic7 is quite configurable and adds an excellent sense of immersion without losing the focus and timbre of the instruments. After the old Logic7 (I have not heard the version in the Arcam, which is not configurable), I like Auro for music upmixing, it does the least damage to the music of the main 3 (Dolby, DTS, Auro).
Both Dolby and DTS upmixers add immersion to music but seem to make a lot of music quite swampy sounding, losing the clarity of the instruments and sometimes change the timbre as well. As always YMMV. I am personally quite excited about the potential of this new unit, as it would allow me (if the Logic16 is good) to retire my MC-12 and my minidsp running Dirac.

I left CEDIA this year wanting wides. I feel they'd give me more than increasing my height channels from 4 to 6, for example. I'm in your boat though, I'm going to wait for the prices (and HDMI2.1). I don't think it will be long at all.

Once HDMI2.1 is out and stable I'll do a receiver upgrade when I can get 9.x.6 within my budget (say less than 2500-3000), and also do a display upgrade. In the meantime I'll put more of my play money toward stuff like cleaning up my rack, upgrading my QNAP NAS, and those sorts of things.

Could you describe in what ways it was configurable? I'm having little luck finding out anything about it. I'm pretty happy with Auromatic for music, but I'm always open to finding something better.

Sure. First is that you have 2 high level choices (for Music): Logic7 Music and Logic7 Music Surround.
Logic7 Music will do front steering of sources, but you have a choice of off and 3 other modes. What this does is allow you to control say how much sound from a source in the middle of the stereo field is steered to the center channel.

You also have control of what they call sound stage which can be front, neutral and rear. This as far as I can tell controls the relative levels of the front vs surround/rear channels.
So if you want a more upfront sound choose front and if you want a more immersive, feeling like you are farther from the stage, choose rear.
In practice, I find this useful as different recordings sound better depending on how much out of phase (ambiance) there is.

You can also choose how much high frequency rolloff there is in the surrounds. You can choose from none to down to 500Hz. The default is 7Khz and I rarely adjust this. This is to prevent too much high frequency energy in the surrounds to distract from the main channels.
You can control the rear speaker delay offset, so you can delay the rear by up to 30 msecs. This is also to prevent the sound in the rears from being too prominent.

You can also set the levels of the side, rear, center and sub speakers.

Logic7 Music Surround is similar to Logic7 Music (you have essentially the same options) but it will (as I understand it) not process the 2 front channels (as an option).
Both modes extract ambiance (out of phase signals) and delay them and put them in the side/rear speakers for spacial immersion.
That I'm sure is a very crude high level description and the devil is in the details, where I think Logic7 shines.

Logic7 Music Surround I like better with acoustic jazz and classical recordings and Logic7 music for Rock/pop multitrack type recordings. There is also 5.1 versions for Logic7 Music and a separate Logic7 Film mode.
It also has a Logic7 mono mode for mono sources which actually can help add a little ambiance to mono sources.

These algorithms were developed by Dr. David Griesinger who pioneered digital reverb in the 70's and who has devoted his professional life to understanding spacial immersion.

edited to add at least a little readability.

Thanks. That sounds pretty cool. Hopefully Logic 16 in the new JBL's will have all that.

May I buy an additional paragraph or two or three?
