I have the B&K Pt3 preamp/tuner. I have no real complaints about the preamp section. Much better than the NAD I replaced. Warm sounding, not bad. I feel that the tuner is weak. It pulls in stations poorly and doesn't sound good. The only advantage is the remote for both. I'd go separate, if I could. That would probably mean not being able to control the tuner w/ the remote, depends if you mix brands of components.
