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.

I have the 2496 in my system. Eldartford, what kind of cables did you use to go from Balanced to Unbalanced? I am using something called a 'Clean Box' from Art Accessories to convert the Balanced inputs/outputs on the 2496 to the Unbalanced In/Out on my preamp. It works ok, but I am thinking about removing the Clean Box and going 'direct' - but don't know how.
Eldartford: Yes, I agree. And I would be willing to give the DEQ a fair shot. But I must admit I would go into this with low expectations.

Like anyone else, I have had several events, a few with local audiophile buddies, where I came out highly impressed from an auditon/test that started with me expecting very little or no positive outcome. And from such times, I am quick to give high praise to such a product. But I have also had enough auditions where the result was terrible, whether I expected it or not and the unit was immediately removed, never to be given a second chance.....it indeed was that terrible.

In the case of the DEQ, I have no doubt the benefits that it would bring. What would concern me here is what harm might it cause in the process. Surely it degrades the sound to some degree. My gut feeling is that the degradations would be in areas where tube-based systems excel.

Interestingly, the line stage and its cable to the amps have proven time and time again to be a VERY critical link in the chain ... and this is exactly where the DEQ or PARC would be placed. Any direct experiences or insights here to this specific concern of sonic degradation?

What accessories do you need to use the DEQ? A microphone, or does one come with it?
Used Tact 2.0s are selling at a little under $1k. Factory refurbs go for $1.5k. They are far superior at room correction and measurement than the Behringer and they include measurement mics and software. In addition to the room correction frequency and delay correction the Tact also includes a 10 band parametric EQ. To put it in readily understood audiophile hyperbole, it's in a whole 'nother league than the Behringer. If you're going to try digital room correction/EQ you're better off spending the incremental dollars for the Tact. The downside to the Tact is that it requires a Windows PC and setup is definitely not intuitive.
