Denon's Audyssey probably had Dynamic EQ enabled i.e. loudness. How do you adjust Trinnov to compensate that? Multiple presets won't do it.
(btw. Monoprice HTP-1 has Dirac (and DLBC ) with 6 presets, loudness with two curves and level calibration, bass/treble with corner frequency adjustments and 16ch PEQ for each output. But it's currently unobtainium...)
That I don't know. Despite having it for a couple of years or more, I'm still pretty much a novice for much of it, just not enough time to listen and tweak (eventually be able to retire and have time for fun stuff).
My Emotiva XMC-1 had Dirac Live but not DLBC (and the newer processors still don't have DLBC after some 3+ years...) Back then the HTP-1 was new and having some issues and I did not want to deal with that again. My XMC-1 worked OK after a bug fix the month after I got it, but a year or two later the HDMI board upgrade was a nightmare. I had to do a lot of tweaking with DL to get everything aligned (mainly the subs) but it sounded OK after that. The SDP-75 (Trinnov Altitude 32, JBL Synthesis version) sounded better out of the box. I am not sure I still have all the comparison measurements; unfortunately when I set it up my REW setup was down and I only recently got it working again (Windows upgrade took out the ASIO drivers).
I took a few measurements using analog inputs to compare the XMC-1/Dirac Live and SDP-75 (plus had old measurements of my Pioneer SC-27, but only using older SW and not REW for the Pio), and my memory of those is the basis for my comments, but at this point it would be opinion since I don't have the data handy. The interesting/strange part is that the center was better integrated with the L/R speakers and a bit more "forward" (probably just louder, but frequency response was smoother than using Dirac Live). The upper end was a little smoother, probably because I ignored/was unaware of the advice to limit filter resolution and cranked them up, and the impulse response was better, mainly less "ringing" after the impulse. I think bass was actually pretty comparable, but that was running the Trinnov Optimizer out of the box compared to hours of tweaking Dirac Live (and the controls on my subs) to get a somewhat similar result. It is possible I could have tweaked the center and L/R speakers more but (a) I spent way too much time getting the subs integrated, (b) I did not realize they were lacking (compared to the SDP-75), and (c) was tired of spending my precious free time trying to get things to sound good.
The Trinnov is wicked expensive and I would not claim night and day difference over my previous AVR/AVP units. I think it sounds beter, and my measurements showed some improvement, but I am as subject to bias as the next guy. At the time I was thoroughly fed up with Emotiva, had gone through three high-end receivers in about five years, was offered a great deal on an SDP-75 (which included EQ curves for my Revel speakers but does
not include the PEQ, alas, though they have discussed bringing it back), and bought into the SW upgradability of the Trinnov to get off the treadmill. Not a panacea, as some things still require HW upgrades, but for roughly half the price of a current top-end processor I could upgrade the HW (not planning right now). There have been several SW updates that added more (and more advanced) codecs plus some other features, something I am not sure other manufacturers do (at least not for long; one guy has a 10-yo Trinnov that is fully updated to the latest SW).
I have no experience with the HTP-1, Storm Audio, Lyngdorf, etc. processors that all seem contenders. Nor the latest Audyssey, Anthem, etc. systems. I recently purchased a Yamaha AVR for my son and new bride (wedding presents) and was pleasantly surprised how much better YPAO worked than on my ancient model (sounded OK with a brief listen, but does not compare to Dirac Live for flexibility). I briefly considered Dataset but at the time it was somewhat a mess and would have cost me significantly more than the SDP-75. I am not sure what I would do today if I had to do it all again given the price difference (assuming I could not get such a great deal on the SDP-75), but am quite happy with the SDP-75/Trinnov.
Sorry for the length, back to work - Don
Edit: It has Dolby's DRC but a quick skim of the manual does not show a generic loudness setting. IIRC, when I asked, Adam or Curt one suggested using a different preset for low-level listening to provide loudness compensation when desired. I have not gotten around to that.
