Power amp around $3000 for C-J Classic preamp

you are offering i am sure well intended but misguided info.((Cambridge Audio 840W - unique design inside, great result.)) Nice amp but Lowish input imp so so match with a CJ tube pre amp

((Odyssey Audio Stratos Mono Extreme - My favorite Sleeper product - in this case the hybridization is German engineering and built in the USA))
Also nice amp
Also Lowish input imp so so match with a CJ tube pre amp

((Musical Fidelity M6PRX - latest 260W offering from the company that thinks power is almost everything.))

Please dont take this the wrong way but Perhaps you could stick to tried and tru endorsements instead of ......

Unsound really offered the most sound advice. The OP seems to be headed toward a wholesale system change over the next year or so.

Decide on speakers first. Then the appropriate amp. Then the preamp.

Choosing a preamp first before speakers or amplifier is really going about it completely backward, and frankly it's a recipe for disaster.

Again, thank you all for your advice and input.
Tvad, you're correct that that's the direction I'm headed, but it seems to me I should still be able to match an amp to the Vandys and C-J preamp. I've wanted to own both the 3As and a C-J preamp for years (C-J even more so), for a variety of reasons. The Classic fits the bill perfectly and even if "unsound," I don't want to discard the idea of owning the Classic just because as a generally accepted rule, I should start with the end. We have the speakers, we have the preamp, now let's choose an amp! I realize the $3000 budged might put some limitation on the choice, but that should still get me something decent, shouldn't it?

CJ doesn't list the output impedance specification of the Classic preamp, so matching with an amplifier becomes more complicated. You should call CJ to get an answer to this important question.

You might be best off with a CJ amp to avoid the matching guesswork.

Whether the CJ amp is the best choice for the speakers you choose is another question.

Good luck.

Tvad, I did notice that as well, which I think is disingenuous on the part of C-J (or any other company that doesn't provide essential specifications for their equipment).
The C-J power amps tend to be very expensive, offer rather low wattage for the price and the top models are unfortunately beyond my reach. Seems the mf-2500a might be an exception, but is no longer in production.
As much as I'd like to own the Classic, I'd perhaps be willing to look elsewhere for a preamp, but I just don't see anything below $2000 that would seriously compete with the Classic. I'd love to own a ModWright preamp, for example, but they cost too much for my budget. If anyone has sugestions, I'd love to hear them. Thanks.
