First off, your speakers are magnificent! I heard the smaller Horning Aristotle with the New Audio Frontiers Ultimate 211 SE amplifier and it was a religious experience for me. The combo was magnificent. I also heard the Wolf Von Langa Sons on the same amp and the combo was once again stunning. I would put NAF on your radar as they make beautiful sounding amplifiers. Just beautiful. The sound is built from the bottom up with addictive body and tone. Great build quality to boot. They make 300b and 845 amps also.
Did I say your speakers are magnificent? Good for you!
Colin of Gestalt Audio Design in Nashville sells Horning, NAF and Tron gear. He is great to work with should you want to visit on NAF or Tron’s first class 300b amp.
