From tubes back to SS?

Sort of.  Ran Manley Mahi Mahi mono blocks for years and they are terrific.  EL 84 is very quick with great bass control compared to many other tube designs.  

Ran Merlin Black Magic monitors.  Then...... traded out Merlins for ATC SCM 40 which are tri-amped with AB solid state amplifiers.

Really, an apples and oranges thing, but the unbelievable control of quality SS matched with drivers and elimination of crossovers is the real thing.  All driven by a tube preamp.

I'm planning to check out a Schiit Aegir just from curiosity, and it's one fifth the cost of a Pass XA25 which was another amp I was interested in (still am). My little Dennis Had SEP is a great sounding amp but, again, curiosity, and I'll keep the Had amp anyway...I have 99db efficient speakers so I can use anything.

@wolf_garcia I've heard good things about the Schiit----even better at the price range too. I eventually ended up with the Modwright SWL 9.0 SE tube preamp to go with my Bel Canto amp. Beautiful sound---great synergy. I absolutley love it. And it's not even broken in yet. 
Please keep us posted as to what you decide and what you think about the Schiit vs the Pass.
