I have heard SOA 2 channel audio in a system built around the Legacy Valor speakers. It’s incredible and I could easily live with it. It relies heavily on DSP to time, phase, level align each specific driver. Amazing system. I am not anti DSP. I have chosen not to use it beyond the subs...

A good topic for another thread. But I have no insight that supports your premise. Those of us who are dedicated to two channel audio think your premise is nice but irrelevant. This thread should be focused on how an AI engine can help the average audiophile optimize their room & system using REW.

Okay! I learn more!

So they have DSP built in that adjusts for the Fletcher-Munson data and conclusions. Cool, that seems to prove my point. At low listening levels, the human perception of music sound quality is more affected by fletcher-Munson than what equipment is used — UNLESS that equipment (speakers) has...

Of course. That explanation of psychoacoustics comes from ChatGPT along with its references. No secret here. I am relying on it to teach me more about this hobby. I was a chemist, not an acoustics scientist. 😀

Oh, and I am using DSP for the subs —The D.A.R.O. Function built into the JL Audio Fathoms. 😀

Yes. It’s a wonderful tool.

I particularly enjoyed the section on Masking and why properly integrated subs help clear up midrange sound. There is actual science behind this stuff.

For sure. But since it’s the science of how we perceive sound, I thought it fitting. Here’s a few semesters of learning from a few key strokes. Crazy AI!! Enjoy ALL! A more complete explanation of psychoacoustics to be thorough. Absolutely — psychoacoustics is one of the most fascinating...

Psychoacoustic is a fancy way of describing our hearing at different SPL levels…

Sure. Here you go! This plot shows approximate equal-loudness (Fletcher–Munson / ISO-226) contours — lines of constant perceived loudness across frequency. 🔍 How to Read It Each contour (20, 40, 60, 80 phon) represents sound that humans perceive as equally loud, even though the required SPL...

Yep. The remote control is not CNC Aluminum and doesn’t weigh 1 lb. 😀 It certainly isn’t what one might expect at this level of audio equipment investment but then again, I bought a replacement Apple TV remote on Amazon and it simply works. Power On/off, Volume up/down and source control...

I believe the psychoacoustic realities are a much bigger impact than the equipment wrt the OPs question.

My hypothesis: At low listening levels, the Fletcher-Munson equal-loudness curves (how our ears perceive bass and treble differently at quiet volumes) matter more than the type of speaker. Horns and high-sensitivity designs can sound more lively at low volume because they preserve dynamics...
