Pre Amp + Amp to run B&W 803S


my budget is $2000 for both the USED preAmp and USED Amp together.I did some research, still novice in this Hifi knowledge.

I am not sure of exact spec's a preAmp should have or even what they are, but I am to some extent aware of the AMP, min 200W in 8 ohms, I am unsure about its Hi current transformer VA values, should be enough to power the 803S.

I am thinking about used Krell KAV250P or 280P as preamp and Classe CA200 or CA300 as the Amp. I will be running this setup as 2 channel only. Your suggestions and Comments are most welcome. Please correct me if I am wrong.

Thank you Mlawitm
More on this. Did more research. As cosmetics are not of any priority, Saw the Yamaha P3500S Amp. heard great reviews about it as well, and costs much less than the british makes. Any input on that. and any suggestions on the preAmp that Pairs well with the Yamaha to power the 803s?

I don't know about yamaha but I do know that I have heard MF with 802's and B&W owns Classe and Rotel. I know that for B&W most run Classe or Mac some Rotel and I chose Pass. It really comes down to your budget and what sounds good to your ears.
To keep costs to a min i chose the following setup,
I know mac's, classe, rotel are best paired with B&W's, but to keep my spending under 2K
i decided to go for Parasound - Halo P3 + Yamaha P3500s + bluejeans cables.

thank you all for the advice
Scorpious,
It looks like the Yamaha is a professional amp--like those found in nightclubs. What drew you to these amps? It looks from the spec sheet that these amps don't even have a single ended input. How are you planning on connecting them?
Just curious.
