Acoustat 2+2 : CJ 2500A or Simaudio W 5 ?

I love the cj 2500 A but I'm looking a little more firmness and impact in the low frequencies. Both my preamps are sweet enough. Just want something that will show a little more what the Acoustats can give me.

I'm probably aiming for the same level but I've got somebody who wants my 2500A and a guy almost next door is selling the W5. He's on a hurry and not willing to give a few days try out in my system.

If you really want to hear your 2+2's for all their worth, try one of the new Sanders Sound System's ESL amps. Monos are the cat's meow, but the stereo version is plenty.

Or if you have $650 to spend try a used PS Audio HCA-2. I'm amazed how well it works with my Acoustat 2+2's.

I have owned the Acoustat 2+2 with the MK-121 transformers for some time. They are now sold (Big Mistake) but experimenting with many different amps I found for the money the Moscode 600 worked better then most, tight base and great mids and highs.
You need an amp that can run very low impedance as the Acoustat’s with the high frequency resister adjusted the speaker can run at 1.5 ohms and the Moscode can handle it with no problem plus it is a great match for the speakers you have.

I haven't heard the combination myself, but Threshold was reputed to work well with Acoustats.
