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.

Its been a long time since I heard the Nak, but I thought it was a little on the bright side. Its been a long time, though. As stated above, the DNA-1 would probably work well for you. Rotel and Emotiva would be worth looking into, as well.
I am about to buy an amp tomorrow and would like an opinion. What is the best $800 dollar amp available used with at least 150 watts per channel? Thanks!
McCormack DNA-1, Odyssey Stratos would be better choices for a high powered amp. You can find either amp for your price and both can be upgraded in the future to bring them up to amazing products through SMc Audio for the McCormack and through Klaus over at Odyssey. Can't go wrong with either one.
+1 to Digepix suggestions.

I took a look at classified listings right now on A'gon and at $800 I'd look at the Aragon 4004 or the Marsh A400S. They more than match your criteria. Support for the Aragon is still available but for the Marsh no.

If you are thinking new I would say really take a look at the Emotiva XPA-2. Emotiva has a storefront on Amazon and are also having a warehouse sale so give them a call.
