Preamps suitable for CJ ACT2 Series 2 preamp.

Hi Vmhf,

that is a magical combination, so you may find yourself hard-pressed to improve it. Query what speakers you use...somepeople like to match the amp to the speaker. In your case, 350 is capable of working with many speakers.

But that might help. I used my ACT 2 series 1 with Gryphon Antileon (Pure Class A SS) and really enjoyed it. You could of course go tubed using CJs older LP140/275, or the newer ET250...or ART amps!!!

The 350 is a great amp that will drive a wide range of speakers. My tube owning friends love it; I am using it with an Audia SS line stage.

With my ACT 2.2, I have used a variety of amps. Pass XA.5's, Bedini 45/45, several SETs, push pull tube, even a Tripath based Red Wine Audio 30.2. All have worked fine.

The ACT's 500 ohm output impedance (average) is pretty low for a pure tube preamp so it should interface well with most amps.

Like Lloydelee mentioned, I view the amp/speaker as a whole. Some amps will "shake hands" with a speaker better than others. Your 350SA will be a lot happier driving far more brands of speakers than my SET would. So consider the speaker when/if you decide to change amps. Don't worry too much about the ACT 2.2 fitting in.

If you have an ACT2.2 - cj350 combo IMHO it is not easy to find a better amplifier for this preamplifier unless you want to go with cj tube amplifiers.

The choice of an amplifier always depends on the speakers, but unless you want to spend a lot of money or if there is an incompatibility between your current cj 350 and your speakers better spend the money in better cables or source :-) !
