I've said it before but don't mind saying it again: Tubes are more fun. These days I use an original version Schiit Freya into a Dennis Had Inspire "Firebottle HO" (12wpc more or less depending on tubes) with 99db efficient speakers. The detail this rig digs out of recordings, the physical beauty of the tubes themselves (no user biasing with these components, but my previous amp, a great sounding Jolida 502p, had user biasing and I liked doing that), tube rolling (unlike transistor rolling which isn't a thing for most people) to change things a little sometimes...all fun...with a couple hundred watts of (2) REL subs to assist. There are no tube subs (or ARE there?), but RELs do use the tube amp signal so there's that. Having said all this I am planning to get either a Pass XA25 or a much less pricey Schiit Aegir to see if I'm imagining all of this so called "fun." The Aegir got a great review in Stereophile recently so that got my attention.
