Pass Labs amps and Avantgarde speakers

Sorry for being a bit of topic but I hope you will not mind my little story.

A few months ago I have attended an Avantgarde demonstration. I had about 1-1.5 hours till the shop was closing and my plan was to listen first the UNOs and then the DUO Grosso speakers. The dealer was king enough to switch the Audio Note integrated initially used with an Accuphase E-560 class A integrated amplifier (I own the previous Accuphase class A integrated, i.e. the E-550). I was so blown away by the Accuphase E-560 – Avantgarde UNO combo that I could not stop the music and go upstairs to listen to the DUO Grosso – I had to listen all the material I brought with me.

Since the Accuphase E-560 integrated (and the E-550 too) deliver 30 class A watts into 8 ohms you may also want to consider these integrated amplifiers.

Good luck!

I tried a 10 watt amp and I have to say... folks who use less than 20 watts for Duo's are simply not doing them justice. They send very anemic and simply cannot keep up and higher volumes such as electronic music, rock, or movies.

10 watts is more than enough power for any Avantgarde speaker. The meters of my Accuphase A-65 power amp (which are very accurate) show that very often I use less than 0.01 watts, i.e. less than a hundredth of a watt. This is actually the problem, very many amps are not design to play music properly in the centi or milli-watt regimes. It is like expecting a car to operate at optimal parameters when driving it between 0.05 and 0.5 miles per hour.
