Thank you all for the advice. 
musicdre:
1.  I like the sound of tubes but I'm not opposed to SS at all.  I should say I'm not sure what would work best for my musical tastes.  Here's some of what I listen to:
>> Portishead, Yes, Pantera, Rage, 2Pac, the Beatles, Al Di Meola, SRV, Pink Floyd, Tool, Kate Bush, Porcupine Tree, etc.  And lots of progressive rock....  

 Lately, I've been going through a yacht rock phase.....
2.  I'd probably lean towards new because I'm not confident that I'd know what to look for in vintage (and I'm impatient!).
3.  Phone input? I don't think so (but never say never....). Everything would go through my PC at this point.
4. DAD - I have a Micromega that I'll be replacing with either a Schiit Modius or Cambridge Audio DacMagic (opinions on these are welcome!).
I'll check out the Cherry STM.
