Which is the best amp for Silverline Sonata?

I'm using a pair of the Sonatinas II with a PrimaLuna Prologue
2 integrated amp 40 wpc tube amp with very satisfing results.
Primalunas are about $1300 new, $1100 used. Excellent value.

I have Sonata III's currently driven with Quicksilver Mono 100's. This I beleive is overkill with 100 watts of power but they sound great. I am going to go with a 300B SET monos not sure which ones. Possibly Wellbourne Tereplane, Ladyday or ??? I would like to hear from Silverline owners using 300B SET amps. Quicksilver has the Mini Mite Mono 25 watts for $998 I believe these would sound great.

Pass aleph series amps sound wonderful with the Sonatas
