I actually don't currently have any such thing (my guitar amp is a Silvertone 1484 Twin Twelve & my bass amp is an Ampeg Rocketbass B-50R), but this is a common question around here, and I stopped lurking and joined 18 years ago just to say the following:
The only power amp I would spend my own money on - and the only one I'd spend your money on if you let me decide - is a Yamaha. In my soundman days I used Crown, Crest, BGW, Traynor, QSC, Peavey, and probably some I'm forgetting; the only one that didn't color the sound, and the only one never crapped out on me mid-gig, is Yamaha. What goes out is exactly what came in (but a lot louder), and they do not quit!
Your turn, Wolf.....
Peter (who is willing to trade the Silvertone - now a hot item, it seems - for a good small Fender.......)
