Power amp around $3000 for C-J Classic preamp

I would think very hard about the Quad 909. I think that with the classic would be a dream. Underwood hi fi sells those at a great discount, and it has gotten rave reviews. It will drive most anything at a conservatively rated 140 per side solid state. Reliable too. Good luck.

Retails for $1500 or so, but sold new at a discount at name above.

I'd suggest a used Spectron Musician III.

I would seriously consider a used cj mf2500a ....... Or McCormack DNA 250

You have a broad choice of speakers with different needs. The Totems need a high quality solid state amplifier with a lot of power to sound their best. I used a 100 watt Krell amp with decent results.
With either the Vandersteen 3A Sig or the VMPS you can use a tube amplifier, but for best results it will have to be fairly high powered.
I personally do not recommend the Quad amp since my personal experience is Quad does not work well with other brands.
As I always recommend, for best results Amplifier and Preamp should be the same brand. The is always a rightness to the sound.
Decide on the speaker first then the right amplifier to drive them properly.

I was recently chastised offline by a Vandy dealer for recommending 80 watt amps for the 3a's. So, whatever you get, make sure it is fairly potent and doubles down to 4 ohms at least.
