Wyetech or Coincident Frankenstein IIs

I want to try some some different amps to power my Avantgarde Unos. I am currently using an Audio Zone Amp-1. I want try try tubes. What are your thoughts on the Coincident Frankenstein IIs, Wyetech Onyx or Wyetech Sapphires to power these horns? I know there are other choices but these amps are currently available to me. I have heard nothing but good things about Wyetech so I am leaning that way. However, Arthur Salvatore considers the Frankentein IIs to be a great amp and the price is not that high.

Let me know your comments please.

Cheers.

Wyetech Topaz the best- does leading-edge transients like nothing else (have owned it- still have another SET 211 amp- love that tube), but then more $$ than the rest of your choices, plus you need a preamp with some 'body' to it. Frankenstein VERY transparent- be aware of that- not 'typical' 300B lushness...

Thanks for the replies. Sounds like Wyetech Onyx are not the best match. My big concern is that I avoid an amp that results in speaker hum as the Unos can amplify any noise.

Has anyone tried the Coincidents, Topaz or Sapphires on speakers that are >100 db of sensitivity?

Another thought, the UK importer of Avantgarde makes his own line of amps, Tron. You may have seen the name on Gon threads. I am not a fan of horns, a defect in my character I am sure, but they certainly made a nice sound with his amps at a recent audition of a turntable. A deathly quiet background, no sound even with the volume turned up. You would not easily get to audition them of course, but he a nice chap to talk to, look up GT audio on the web.
