IMO Not much diff between PA7 and HCA2200. The Nak is a tad more detailed, the Parasound a bit warmer and looser in the bass. The Halo A23 series would be a step up though.
I have owned a Nakamichi PA7 amp. How would you
compare it to B&Ks sound or Parasound like the HCA 2200II. I have Kef 104/2 speakers and I would not describe them as bright. I would like a little more forward sound than I had with the Nak amp powering the Kefs. What amp would match up well with these used under a grand? Amp and then what affordable used preamp with remote control? Thanks.
