By sound I meant clean power, low distortion, purest internal discreteness (not sure that is a word) you know what I am talking about no need to correct. I too could use terminology but why do that becuse others can benefit that are not technical.
He's not using complex terminology. He indeed is a professional in the industry, and also happens to be a very interested consumer/hobbyist (trust me, a lot of the pro's don't really care).
He's just trying to help. While opinions do vary regarding any certain feature or product, I will share mine regarding this, ahem, room correction. IMO, it is by far the most value-laden feature available in a midlevel receiver. Now, instead of playing the refutation game, you
could simply either use search functions, read a bit more, or kindly ask him to expound a tiny bit. There is really no need to bite the hand that feeds you. Ok, that's out of the way:
Room correction devices are NOT substitutes for poor speaker design, poor speaker placement, poor listener positioning, lack of treating the acoustical environment, whether absorbing primary reflections, or trapping bass, etc.
But IMO a good one helps a lot still. An advanced products like Audyssey MultEQ XT (please note the XT) is had on my refurbed Onkyo 805 for way under your budget. I was so impressed what it did for my HT that I wanted to couple it to my multi thousand dollar stereo system, but the economies of scale in the much smaller 2ch world prohibit affordability. I basically would have to either use an HT receiver acting as pre, or I buy a $2,000 SEQ.
Why did bandphan mention Denon and Onkyo? Because they sport Audyssey product, as does Marantz and NAD. He himself uses a Pioneer, and some folks really enjoy that MCAAC can be fiddled with post calibration. You can't quite do that with Aud below the pro levels, but certain products come with more target curves than others.
Such a product will be more accurate than your SPL meter, it will measure the reverberant field with consecutive sweep bursts, finding and applying, ahem, correction to even secondary reflections, and perhaps most importantly, dial down modal ringing. Again, it's NOT the end all, but a great tool to have in your arsenal. For, IMO, the acoustical environment is by far the most important thing to consider in audio. Just as a Panasonic in a light controlled environment will outperform a Kuro with terrible ambient lighting conditions, a mid level speaker in a well prepared environment will outperform high end speakers without any thought to said environment.
If you don't want to hear it, just say so. Put us on ignore, whatever. But, we are only here to help, and not to confuse. Note that bandphan didn't mention modal ringing, or secondary reflections, but just simply "correction". He was indeed talking as simply as one possibly could about these products that you will undoubtedly find on any receiver you choose. Better to know now, than after you bought already, no?
