I'm not sure what kind of music you're into, but my speakers of choice have always been JBLs designed for live use.
That's a cool idea, and I agree with you that big speakers give you a little extra something, but if I went big I'd have to do it right, and I don't have the space in my room for big Tannoy corner speakers. Also, considering that a Japanese diplomat offered Abu something like ten grand for his older-than-my-parents'-marriage Tannoys recently, I doubt that I could afford new ones.
When it comes to amps, though, I think everyone should agree w/me. Ditch the all-in-one units and get a dedicated, two-channel power amp.
Actually, I do have a separate amp. I miswrote earlier. The switching part (i.e. the preamp) is part of the CD stacker/tuner, not part of the amp. (Both components are mini-sized, and together they're just a little bit wider than my PowerBook.) But I'm not replacing any of that stuff. It still works fine, and the remote has a solid-feeling aluminium case that feels better than the plastic remotes that ever some high-dollar stuff is shipping with. Besides, I've also bought two cars and put a deposit down on a third, in the last month, so cashflow is a real issue. Going to stereo shops makes one realise that quality hi-fi has its own bizzare little culture, kind of like decent clothing. They have their Paul Smiths and Etros that no one outside of their little circle has heard of. I was inundated with strange names, like Krell, Mark Levinson, Cary, BAT, and Anthem. I'm going to hit some different ones today, and who knows, maybe I'll come home with something. Peace, JG
