First of all, I think your short list is great... these are really outstanding choices. Any would be great choices. But I think, given the efficiency of the speakers I would go for the Conrad Johnson. All the choices you mention are known for the characteristics you speak. Efficiency points to the CJ.
ProAc Response 2: CJ CAV45, Cary SEI 300B, or Cary Rocket 88?
Looking at the amps listed in the title to pair with my newly acquired ProAc Response 2: CJ CAV45, Cary SEI 300B, or Cary Rocket 88
Looking for the best tone and most in-the-room presence possible. Also want tuneful/rhythmic bass vs depth/authority.
Any feedback from those who have heard any of these, especially with ProAc would be appreciated.
Thanks!
