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!
