I have had virgo's since the day they were bi-wired and have tried many amps,solid state and tubes. first I have a vac 30-30 tube amp it does a great job but delivers a great deal more of power. I have used the plinius 100 watter the art audio 24 watter and a few more.this speaker needs plenty of power due to the 4 ohm load and this speaker also is speaker wire dependant. also one of the responses that you got referred to alan levinson as the importer,it is alan perkins at immedia.have fun listening
