I would probably burn with the house. I have too many guitars to carry out with the amps. (they are all Carvins, reason why my pictures are there) A Favorite?, hard to say. The RA100 with the original V30's from the Mesa cab sounds awesome. The EV in the Mesa cab and the Mark V has its own awesomeness. Not to leave out the Mark IV. Fane Studio speaker, and the extension cab just adds so much depth (just two speakers and it nearly puts to shame both the MKV and RA100). Not pictured is the Carvin V3MC, that comes close to the Mark IV in sound, and kick with the extension cab in parallel. That is not a bad little amp, for $600 bucks, it was worth it.
I like all of my amps the same, also they are like my guitars, some may look similar but they sound completely different. There is no one amp that does it all and sounds good doing it. The Mark V comes close but does not get the classic tones that the RA100 can dish out. The Mark IV is quite different too, sounds nothing like the V or RA, just different. Also it is the only amp in my collection that can run an integrated quad (EL34 + 6L6GC at the same time). Can't do that with RA100 or the Mark V (original manual had some errors and said it was possible, that was changed shortly thereafter).
I like the CH2 Hi of the RA, but the clean channel with some edge dialed in, -3db power soak and single coil bolt neck guitar and WOW. I spend a few hours with the amps and a few guitars. I got lost with the Carvin Bolt (similar to Fender Strat) which has a Floyd Rose. I never really cared much for bolt neck guitars, but this one just sounds amazing and plays silky smooth. I never like Floyd Rose tremolos either, but that guitar would not be so great without it. I prefer my Kahler bridge guitars, but why do I like that bolt guitar so much is beyond me. Sometimes I can't believe it is me that is playing when I play with that guitar.
