Solid state to tube

I bought one of these a few years ago and it’s been a pleasure to use. Not a rebuild, but a brand new replica using the Latino VTA driver board.  Built by Chris Keller, a very fine gent, in NC. On the other popular resale platform…
FOR SALE: Dynaco ST-70 - New - Custom Build - Beautiful!

There is also this: FOR SALE: New build: Dynaco Pass 3 (M) preamp (reduced price)

These will get you into tube sound without the inflated pricing, but with the quality of sound.

can somebody tell me the absolute worst kind of music/sound recording to play through tubes?

It's my opinion that small signal music seems better handled through tubes though there may be some tube noise in very small signals like LO moving coil cartridges amplification. 

It seems to be more of a toss up as the signal strength increases through amps.  Then it's how good the designer is and how their equipment is voiced.  My preference is for a particular type of solid state amp design.  But my preamp is all tube and phono stage is hybrid.    

Quicksilver is great equipment.    I just pulled a pair of Mid Monos out of service and they were one of the best amps I've ever owned.   Seriously good stuff for the money. 

Cannot say enough good things about Quicksilver. I own Mono120s using KT120s and drive them with either his Line Preamp (6922 version) or my AI M3B, and this is an end game set up for me, period. The power, dynamics, and naturalness of instrumental timbres (woodwinds, cello, French horn, lute, piano, etc) are just "right" sounding.
