Amp for Vandersteens 2ce sig 2's

I've beem using the Audiable Illusions Modulus 3A with a Music Reference RM9 MK II for about 15 years. I've settled on 6550 tubes but the KT88 is tempting. I like the Chinese 6550 as much or more than, the Winged SED 6550 when listening to overly vivid recordings... but then, excellent recordings sound a bit muffled. I hesitate to upgrade to the Modulus 3B and the RM200 Mk II because I'm afraid I wont like them as much. I've used NewForm,Maggies,Totem and now, modified NewForm's...Tiare, with great success. Hope this helps.

Classe is very fine with Vandersteens. I used to have them with my CAP 151, right now, they are hooked to a NAD 50 watter in the den with tv/movies and really, they sound quite good.
Ayre is also very nice, my dealer uses this with Vandersteen a lot.

I would go Vincent Audio sp 331, or 331 mkII hybrid amp,would take large amounts of cash to beat this amp for the price.

Recently puchased used Belles 150A Hot Rod from Audiogon.
It's really my first soild state amp as I have several tube
amps. The match with the Audible Illusions 3B is awesome.
Makes me wonder what the Belles 150A Reference sounds like?
I do like tubes..but, this is a great match.

Might be a little over kill but, I now have a pair of the McIntosh MC601 mono block (600watts ea) all I can say is WOW! my 2ce sig 2 really woke up. Bass got tighter and deeper, soundstage got deeper and wider, and way more cleaner and clearer. I'm also using the McIntosh C2300 tube preamp with Telefunken tubes. I tell you, the 2ce Sig 2s are way underrated. I had compared them to speakers that cost 5 times the cost and the 2ce sig 2s are either sound better or just the same. I also noticed that Vandersteen speakers are amp friendly, any good amp will make the Vandersteen sounds great.
