Avantgarde Trios, SETs, and Impedance Curves


Has anyone ever seen an actual impedance curve plot for the Avantgarde Trios? I am about to acquire a 3 year old pair and need to find a great amp to drive them. I suppose conventional wisdom would be to use an SET of some kind. However, to perform their best, SETs really require a relatively flat impedance curve. So, I guess what I'd like to know is how badly does the Trio impedance fluctuate with frequency, and/or, empirically, what amps have Trio owners used that have rendered awesome performance?

How about it, Trio owners, any advice for a new Trio guy? Any feedback would me most appreciated!

Dean,

I presume if you're buying Trios, your budget isn't too tight. With their 107dB/W efficiency, the ampifiers will have to have minimal circuit noise, or else you'll hear it in the quiet passages of the music. Some of the amps which I know work with Trios include
Audiopax 88
Tom Evans Linear A
TRON 300B (Cantata) or Jubilate amps
Shindo

The Trons are designed to work especially with AG horns and are essentially bespoke amplifiers made in the UK to order. The US distributor is Jeff at Highwater Sound. If you can, have a listen to them. They may look expensive, but sonically they're a bargain.

Best wishes and good luck

Dean,

The Tron 300B is about 15-20k USD. The TEAD Linear A is about 8-9kUSD
