Please help - 3 top-of-mind choices for Avantgarde

I received the Welborne 300B (Laurel) amps and sound great with my UNOS, the best option comapring in the same system with five different amps, some costing 5 times more.

Glad.

I've heard duos with a wide range of amplifiers. I think that they are pretty forgiving, as far as amps are concerned; they sounded good with a wide range of amps, including those I normally don't like (e.g.,Cary 805). I particularly liked them with the Art Audio PX-25, the Viva Solista and Joule OTLs.

Larryi-I would love to trey my amps with the Viva or Art Audio amps, as well as Wavac, currently I am focusing on matching the welborne with a good preamps since I am running direct to the amps via the variable output of the Accuphase CDP I own.

Thanks for sharing your thoughts.

I use Viva Aurora monoblocks (845) with my Trios 2.2. It is a lot of power for Trios. I tried an Atma-spere M60 MKII and it was not so good. The high frequencies were very rolled off and the overall sound was a little dead. There must be an impedence dip in the Trios tweeter. I did not here this in my Silverline speakers. It sounded quite good, but the OTL is no SET. Even playing rock music when I throw a party, the SET sound is still more engaging on my Silverlines. The bass is a little less tight though. The Duos might not have this problem that I noticed in the Trios. This was in a direct comparison with my Vivas.

I really like the sound of the Viva, but want to try something else also. I have in mind the ART Audio px-25, lots of talk on this with Duos, and the Wavelength Cardinal X-1. Has any one compared or have comments on these three with Duos or Trios.

I am a big fan of biamping, the Avantgardes are already biamped, since they come with the active woofers (subwoofers would have to cut lower than 250 hz!!)
I think SETs would sound great on the top (with both horns).
The lower freq would have to be cut from entering the SET amp though...
Anyone biamping? Active XO, Passive Line Level XO? Etc.
