Preamps suitable for CJ ACT2 Series 2 preamp.

I have a CJ ACT2, Series 2 preamp with a CJ Premier 350SA poweramp.
I am genuinely very happy with the sound but want to hear what other poweramp options others may have used with my CJ preamp.

Thanks in advance.

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!!!

CJ tubes to start with? If the big boys are too much, you can get the older big boys and have CJ replace with teflon capacitors...'Downunder' here on AGon has done this to great success. Or you could monoblock a pair of older MV60SEs.

For example the SF STrad was 4ohms nominal...but actually 2.7 through 2/3rd of the spectrum below 700hz or something. CJ does not quite double down thru the impedance range...600Watts at 4ohms as i recall...but that is still reasonably powerful. in any event, you may find the higher powered tubes have very high current and are able to really drive the YGs. In the end, SS Class A (Boulder, Vitus, Gryphon) are probably some of the most powerful amps that come to my mind. I am told Vitus is closer to Gryphon than Boulder in character. good luck and pls keep us posted if you hear the CJ tubes.

In any event, 50 totally normal for me. The power amp should not be fussed by the preamp either...the power amp will be more fussed by the low impedance of the YG, and my guesss is that the 350SA is up for it without much problem. Good luck and enjoy! If you really want to know the truth...speak with Ed at CJ directly. He is super quick and very knowledge and friendly.
