Power amp around $3000 for C-J Classic preamp

If you decided on Vandersteen 3As and you want good sound forget about CJ and go with Audio Research. There is always plenty of used Audio Research available and once you've heard Audio Research with Vandersteens you will have no regrets.

I called C-J and the Classic's output impedance is 200 Ohms. If, as general rule, the amp's input impedance should be at least 10 times the output impedance of the preamp, all of the amps mentioned in the thread should work just fine with the Classic. Even though the Classic has a higher impedance than most solid solid state preamps, any amp with impedance of more then 2k Ohms would comply with this rule. The lowest impedance of 22k Ohms for the Odyssey is still over 100 times higher than impedance of the Classic. How is that "lowish"?

Actusreus,

Good to know and a good point. While I have been told and/or read that the PrimaLuna pre is a bad match for amps like the Stratos, I cannot see that impedance mismatch alone could be huge problem for pairing the cj Classic with any of these high value solid state amps given an output impedance of 200 Ohms.

Audioconnection's point about sticking with tried and true combinations may more appropriately apply to speaker/amp interactions in this case. I tried to suggest the amps I like below or around three grand new that could drive the hungry 3A's. These should all sound "good". Whether they will sound as good in combination with the 3A's as many here suggest ARC gear will sound, I cannot say but doubt it. In many cases you get what you pay for. ARC pre's and amps are listed here all the time used, and sell faster than pretty much any other brand.

No matter what direction you go, good luck, the Vandys are nice speakers.
