Whats the FATTEST sounding Tube amp to warm up Lean speakers?


What would you say is the fattest, warmest fullest sounding Tube amp to fatten up
Merlin VSM's?

They are 8 ohm, and easy to drive. 30wpc would do.

From my understanding, through reading here, the Famous match with AtmaSphere s30 actually doubles up on the natural detailed and spacious yet lean character of the Merlins.

Which Amp would do the opposite - be a little forgiving and sweet in the higher mids and fatter and fuller in the lower mids?

Thanks

The Mid Monos are designed around EL34 and that's what I'm using now...

KT 88 does sound "fatter" ,  but it's always best to have a speaker that appeals to your listening tastes rather than trying different gear to "tune" them 
Thing is this speaker appeals to me in many ways but not all.

Since this is the biggest most cumbersome piece in the chain, im trying to adjust to it before i give up and continue schlepping more speakers that may or may not work in my room... But essentially of course you are right...
I've been to many shows and always very impressed with the Merlin's... I've heard them driven by Joule and Atmasphere and would not venture from those two brands based on what my ears told me.

Good luck.
