The UK importer of Avantgard, Graham Tricker, is a great enthusiast for the speakers and of course, is Tron Amplifiers also. I don't know that Tron amps were voiced with Avantgard in mind, but they did sound very good together, when I went to pick up my turntable.
Tron are well respected anyway, try googling the name or GT audio is his UK website
