Room Correction Systems and Electrostatics?

Yes, you will be amazed. I use the Copland DRC-205 with my electrostats and it is great. Go for it!

Good Luck

I have ML Summits, and my room adds some nasty bass nodes. I happen to have a Denon 3808 (for HT use) and tried the Audyssey MultEQ XT with my Summits. To my ears, it did an admirable job in taming the bass, with little loss of musicality. Ultimately, I plan to add some bass traps and acoustic panels, and hopefully won't need to employ EQ. I suspect Tact, Lyngdorf, or DEQX would likewise work for your Quads, but optimizing acoustic treatments first is what I would suggest.

Yes. I used, among others at different times, Soundlabs and PK restored stacked 57 Quads, driven by SS and tubes at different times. A Tact 2.2 XP helped tremendously. REmember, too, that the TacT, Lyndorf types correct for phase and arrival times, too. With phase correct speakers (single drivers included), you'll almost certainly be well pleased , more likely, amazed at the level of articulation and tonal balance.

I don't argue with the religious zeal of the analogue fan, I have nice analog and if I could avoid the DAC issue, I'd love to, but that's a necessary evil with TacT/lyndorf. With that, I have an uneasy truce. Rives, anyone?

However, in my system, in my room, I wouldn't even want to hear it without High quality EQ. I know what music sounds like and have over $90k in a sytem. Trust me, without EQ, my room sounds terrible.

Some of us don't have rooms that will work with us, dimensionally or otherwise, and that CANNOt be corrected with traps, panels, etc. Electronic treatments are just necessary at that point. Maybe I'lll have a better room one day (my equipment is just fine, thanks), but for now, I swear by room EQ. It doesn't matter if it's di-polar or not (I'm using Lowther single drivers now and it still sounds pretty good).

If your only problem is in the bass region, you should consider a Rives Parc.
It can attenuate 3 different frequencies, and is completely analog.
Disclaimer: I will be putting mine up for sale in the near future.

As has been stated--no EQ is the best EQ if you can get away with it. However, problems in the bass sometimes require large, heavy and expensive devices to deal with the bass problems. Sometimes, there is no passive solution for the bass at any expense given a room's size and dimension. If that is the case, the Rives Audio PARC is the best solution as it has no A/D or D/A conversion. It works only in the low frequency and is designed with 118 db signal to noise to have the least possible effect on the overall signal.

Buy Carl's PARC--he takes great care of his equipment. And if he already sold it--well, we will sell you one.
