Bro, what?
Have you even read Amir’s objective RP review which shows actual before and after results?
Sigh. Please read more carefully. I cited this testing way back in
Post 12 of this thread. The same post where I referenced the measurements (including bass management) by Dr. Olive’s team.
I’m also experienced enough to see the extreme limitations of testing room correction on a pair of full range speakers. (I feel some Deja vu here: the confederate flag guy used to overinterpret Amir’s Audyssey testing similarly; maybe still is but I’m not seeing them.) No bass management, let alone playing with some of the more interesting configurations Lyngdorf offers, such as “boundary” (flanking) subs and separate LFE.
It does an OK job, it doesn’t do a better job than Dirac Live (which I have extensive and ongoing experience with) and seems to do a similar job to XT32.
I’m not sure how you’re defining “better” or “similar” here. Are you just looking at graphs and seeing that one happens to be flatter than the other?
If your argument is that Audyssey/Dirac throws more at hammering the response to fit a predetermined target curve…sure, that’s true. I think we need to go beyond that. Listening matters. It’s indisputable fact that RoomPerfect is only commercial room correction system that, under controlled conditions, was preferred over no EQ.
People seem to give RP a pass because it’s a luxury product and because it’s essentially a black box like YPAO and Sony’s latest room correction. They don’t let you look under the hood, and so people make all kinds of assumptions about the quality that are probably overly generous.
To repeat myself, it’s indisputable fact that RoomPerfect is only commercial room correction system that, under controlled conditions, was preferred over no EQ. Yamaha or Sony can’t claim that.
Some of us have measured what it does, as well as XT32 and Dirac (basic and the far more useful DLBC) on the same loudspeakers in the same room. Unfortunately without the benefit of being able to optimize the system to maximize use of RP (speakers close to wall and “boundary subs.”
But…you’ve given me an idea. I recently picked up an Anthem MRX 520 (ironically perhaps, to replace the Lyngdorf 1120 in the guest room; that was always a temporary spot for 1120, pending some bedroom renovations). Thats means I’ll have reasonably current hardware with all the systems, except Trinnov, on hand.
ARC - MRX 520
Audyssey XT32 + iOS app - the Marantz AV7703 boxed up in our basement
Basic Dirac - miniDSP SHD Studio
DLBC - HTP-1
RP - TDAI-1120
We also have an occasional use 2-channel system that could be a test bed. I’ll have to noodle on how to implement - right now the system requires the superior feature set of HTP-1: PEQ to equalize the passive small closed box subs in the front corners, DLBC to integrate the 5 subs in current use. But objectively (REW Pro and 4 iSemCON + 1 Earthworks M30 mic make that reasonably quick) and subjectively characterizing each on the same stuff could be a summer project.
I DO use two subwoofers in my HT setup, which is something XT32 handles well,
We have very different definitions of “handles well” I guess…
I could buy an SDP-58 on Harman employee discount if I felt like it, and I haven’t. Think abt that.
What’s to think about? We’re already aligned that the pricing of that particular box is batshit. I wouldn’t expect the Samsung employee price to be that compelling as a result. Also its promised unique selling points appear to either be absent (Logic16, free upgrades to new Dirac tech) or buggy (Dante).
Lyngdorf tells their customers (and the community) essentially nothing about how the product does what it does. What's the filter resolution? How many taps?
Respectfully, Lyngdorf’s customers don’t give a damn about any of that nerd shit. And one basic band of PEQ deployed smartly is better than a trillion “taps” or whatever used badly.
