EQ's... why doesnt everybody have one?


Just browsing around the systems on this site, i knoticed that very few have equalizers. I realize some claim they introduce unacceptable noise but i would hardly call my Furman Q-2312, at %>.01 20Hz-40kHz, unacceptable. This $200 piece of equiptment ($100 on sale at musiciansfriend.com) replaces several thousand dollars in assembling a perfectly linear system in perfectly linear room, and in my opinion, accomplishes the task better than any room design could no matter how well engineered. It brought my system (onkyo reciever, NHT SB-3 speakers and Sony CD changer) to a level i could not have dreamed. It extends the SB-3's frequency response by at least 10 Hz to a satisfying 30 Hz without any rolloff or sacrifice in clarity, but the greatest improvement was definately in the Mid-range, around the SB-3s crossover frequency of 2.6kHz. The clarity of vocals, strings, guitars, brass... anything in this range rivals that of uneq'd systems costing well into the thousands of dollars... my total cost; $800. One of the more supprising differences is a marked improvement in immaging, it think this might have to do with eliminating several resonances in the right channel caused by my back wall (the left back wall has a curtain over it). The second my dad heard the difference he got on my computer to buy one for himself, he couldnt even wait to get back to his own, he then kicked me outa the listening chair and wouldnt get up for the better part of an hour.

Everyone...My computer has been down for several days. Just two final comments.

1..People who have not listened to the DEQ2496 should not comment on its sonic qualities. The price means nothing. (I forgive you for this sin because I once thought that way too).

2..Noone should put out incorrect comments about features that the DEQ2496 does or doesn't have. (Like delay). For those with no hands on experience, the 22-page DEQ2496 manual can be downloaded from the Behringer web site. (Can I do that for TACT?).
Eldartford, can the Behringer delay one channel versus the other to compensate for small differences in speaker distances? If so, is the adjustment done automatically as part of the room correction process? What microphone do you recommend for use with the Behringer? Does the Behringer calibrate to the mic or are mic frequency response deviations left uncompensated. Also, what is the bandwidth of the narrowest response peak/dip that can be corrected by the Behringer?

It may sound like I'm anti-Behringer, but that's not really the case. The Behringer represents an outstanding value in terms of features and performance. My point is that there are better units out there for room correction especially if you go beyond bass EQing). In absolute terms the sonic differences between these units is not that great, but in audiophile terminology, the differences are not subtle, huge, shockingly dramatic, unbelievable, jaw dropping and possibly the single greatest advance in audio in the last 30 years.
