B&W 800 series speakers love power. Add Pass Labs X600.8 mono amps to your list. Also, I am sure the MSB preamp section is decent but if you want better layering, better soundstage and more natural sound, consider adding a good linestage in the future, solid state or tube.
New to the B&W 801D4
Just took delivery of the 801's and looking for amplification ideas. Currently using BHK 300's with MSB Discrete running direct into the BHKs. Overall relatively pleased with this combo but looking to gain that last bit of control and imaging. I have a reasonably large listening room i.e. 30 x22 with 8ft ceilings. Having researched the various online threads / reviews seems all I see are the usual suspects .. Classe Delta, Mcintosh etc. I auditioned with MSB S202, and smaller Vitus integrated. Any other owners out there have good experiences with SS or tube gear in the $30k range?
