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.

Concerning the Rives, I have playing with one between an Aesthetix Callisto Signature and either CAT JL-3 or Wolcott P220 amps. IC's to/from the Rives are Purist Dominus. With simply using the Bypass switch on the Rives, there is a significant improvement with the unit in the loop. The reduction of the bass peaks brings on a huge clarity especially in the mids. However, when I remove the Rives and the one Purist Dominus IC from the system, there is a substantial increase in dynamic contrasts. I can only imagine the far greater losses with other less resolving ICs. Speakers here are SoundLab A1s.

In the context of a top-notch music based system, the Rives is a tough sell in the final analysis unless you have no other options to resolve the bass peaks with room improvements. In the context of a home-theatre based system, the Rives would be very welcome as it cleans up so much of the mids and the final last bit of loss in dynamics would not be an issue for me. Highly recommended but very system dependent.

Could there be a correlation between the "reduction of the bass peaks" and the implied loss of dynamic contrast? Just wondering........

Presumably he's comparing the Rives in Bypass mode with the Rives out of the system altogether. Or maybe not.

Well...just a an impression or fear....I love the way Meitner does SACD and concerned that any digital processing requiring conversion into PCM would rob some of the unit's unique merits. Rives as an analogue parametric device is potentially more interesting but if Jafox is to believed then I am not sure either...as always probably will have to experiment.

Also note Zu Cable's Definition speaker and the Pro-version which both have bass parametric equaliztion built in and which is adjustable. If you download the catalogue you can read some interesting things they have to say with room attenuation etc. I am auditioning them this weekend.

I would not be without an equalizer because I value quality sound reproduction. I do not use it more than half of the time. Got to be honest though, some of the Redbook CD's are unlistenable w/o the equalization. Likewise with some of the vintage vinyl. Even the 200 gram Rolling Stones "Exile On Main Street" benefits from the equalization I have. And that lp is one of the most poorly engineered that I know of. I am a purist, meaning that I seek a natural sound. But the equalization certainly "saves the day" in a good number of instances.

I do not understand why admiting that one uses equalization from time to time makes them a candidate for expulsion by the "bad taste" police.
