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.

Coincident is far purer (less grit) and engaging. Sapphires have a SS-like edge artifact that is not appealing. I am an ex-Topaz monoblock and Onyx owner so am quite familiar with Roger's offerings.
