In response to Mijostyn: I do tune my room using both home-made absorbers and diffusers and also commercial products that do the same. I aim usually to eliminate any nasty peaks that are inherent to the room, and that's about my only goal. But to paraphrase Joe McCarthy's famous question, I am not now, nor have I ever been interested in electronic methods to shape the frequency response of my amplifier/speakers. I do modify my electronics and in one instance a speaker crossover, in order to improve upon the interaction between electronics and speakers. The goal there is always compatible with a flat response at the level of electronics. As I mentioned elsewhere, that was particularly important with respect to the Sound Lab 845PX crossover. In general, my opinion after 45 years as a hobbyist is that if your own choice of room/speaker/amplifier/front end equipment does not already get you 90-95% toward your own audio Nirvana, no amount of tweaking per se will get you the rest of the way. That includes ICs, power cords, NOS tubes, boutique parts, and various add-ons that closer to snake oil than to common sense. The ICs, power cords, etc, can embellish, but you can't turn an audio sow's ear into a silk purse with gadgets.
What interests me is that in some posts you sound like you have been in the audio business, but from other posts I gather you are a physician, likely a pediatrician. Since those to professions are quite different, I wonder which is correct.
