Tube Amp for GR Research LS-6

So, I am looking to sell my current SS amplifiers, and move onto to something tube perhaps...

I feel like I am overly sensitive to SS sound; even the slightest bit of glare or edginess drives me crazy.

I am confused about tube amplifiers, and how they relate to performance goals...

I like to listen to music pretty loud; 90-95 DB average with peaks in the 105-110 area...

My speakers are 90DB/1 W/M.

I am assuming that I need something in the 200 watt area to achieve this goal via the math on paper correct?

So, that limits my choices based on budget correct? Looking to spend around 4K.

Any suggestions would be greatly appreciated.
