Which is the best amp for Silverline Sonata?


Recently purchased a pair of Silverline Sonata.
NOT having good sound at all with my Marantz PM-17.
Blurry, no focus, lifeless...
Its like a speaker with a blanket over them.

Heard the Silverline Sonata are better with tube amps.
Want to know if you guys have some recommendations for me...
Any inputs are greatly appreciated! Thanks!

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.
I am using Atma-sphere M60 MkII.3's with a passive preamp. Superb clarity, imaging and soundstaging. Previously Manley 120 watt tube monoblocks - softer, warmer, tubey. Not as quick or authoritative in the bass department but clean & satisfying.

I guess I am saying perhaps your speakers are showing weakness upstream and yes-tubes!
Silverline voices all their speakers on Pass Labs gear. The X series......X250.5 would be magical.
They do like watts folks. 100 watts really opens them up and brings them to life. Any good tube amp will make these sing. 70 watts or more are better. Yes they sound good and even great with 10 SET watts, but 70 watts or more from CJ, Bruce Moore or Mcalister Audio will floor you.

Blue Circle or Monarchy hybrid amps work great with this speaker also.
