Parasound vs B&K vs Acurus


I currently have a B&K ref 70 preamp and PSB Silver speakers with an Acurus 200 watt amp. The sound is quite nice.

I'm wondering if there is much advantage to moving into a B&K or Parasound amp, or all the three about the same in terms of sound quality?

Anyone with experience comparing the above amps please post and let us know your thoughts.

Thank you everyone. Great information so far.

Bdgregory: I can attest that the Acurus is NOT a bright amp at all. If anything it might need to be a little more open in the highs, but thats just my experience with my decent/ok equipment. Bryston was quite bright and felt thin in my opinion. Nice punch but not something i'd listen to all day.

So if a person was to upgrade, what 'hi-fi' brand will sound warm and detailed without breaking the bank? I'm going to avoid Bryston.
Mar- Maybe odyssey audio might work for you;I would give Klaus a call and talk with him about your system and goals;he will give excellant advice and like Ralph from Atmasphere will not jam his gear down your throat to make a sale.
I don't know about the other brands, but I bought a used B&K 200.2 a few months ago and I love it. I switched from Carver and the B&K is a much more nuetral sound. I'm driving Paradigm Studio 40's which tend to be bright and this helped calm them down. I got it for $650.00 and have seen them going for less than that on here.
If a person wanted to step up from B&K/Acurus etc, what is the next best thing for the money? Classe?

Are classe amps neutral/warm?

I'm using PSB Silver speakers with a B&K ref 70 preamp with a sony ES sacd player.
Classe will have a smoother sound. Other option is to add some bypass caps to your current amp, to tame down the harshness you are hearing fro mthe filter caps.
