For my TRIO Omega with a pair of Basshorns, I am using a pair of Antiphon Monolith 300B SET monoblocks. The Antiphons produce 7.5 perfect watts with lots of current reservoir (its power transformer is 600 watt capacity) Due to its enormous power reservoir and huge damping factor, it can drive a speaker with a very difficult impredance curve. I have directly and indirectly tried many amplifiers for Avantgardes, but nothing comes even close to the performance of Antiphons when it comes to driving a highly efficient speakers with huge drivers (15 inches or larger)such as Tannoy Westminster Royal HE, etc.
One of my friend is also using the Antiphons to drive his pair of Wilson Watt/Puffy speakers(known as a very difficult impedance load despite of its good efficiency at 92dB). The Antiphons surprisingly replaced his former amplifier, Boulder 2060 stereo amplifier. My other firends are satisfactorily using the Antiphons for Avalon Eidolons and Rockport Technology Antares.
As you can denote from the above instances, the Antiphons are outstanding at driving a speaker with highly fluctuating impedance curve.
If you want more reference or photos, please let me know.
