Amp suggestion for Merlin TSM speakers

Signature Sound services Merlin speakers and imports Ars Sonum tube integrateds which I think Bobby was originally importing and using with his speakers.

That said any good pushpull amp in the 15-25 watt range should do just fine with those plenty of choices out there. Synthesis from Italy is another brand worth checking out.

For the past 12 years I’ve used a Manley Stingray II with my TSM MME. They mate beautifully.

A buddy of mine recently passed away and we are liquidating his audio system. Bobby’s last Black magic VSM MXM with master Bam and an Ars Sonum Filarmonia integrated as recommended by Bobby. 
For a medium sized room this is a great combo. Liquidating for the family and the combo will be very reasonable. 

 I heard them  a few years back being driven by a Rogue tube integrated. The sound was beautiful.

I second the VTA/Tubes4hifi amps. Currently running twin M-125 monoblocks and their SP-14 preamp. I built the amp kits and had them build the preamp while I was in the process. Very rewarding listening to something you had a hand in bringing to life, but don't kid yourself, these are solid, powerful and musical regardless of who built them. I'm extremely satisfied with the investment, getting ~125 watts of tube power from each of these is awesome.
