Avantgarde Duo 2.2 Amplifier Match.

Hi all,
I'm currently running my duos with an Arc VT100mk11. It sounds very nice after a bit af wailing and Gnashing of teeth at the start(I had tube problems at first). Anyway, I'd like to try the Lunatic Fringe that is SET's. Has anyone tried the Yamamoto A-08s with the Duos. I'd be very interested if anyone has. It seems to be very good value for money at around 2,200 usd. I'm probably just going to order one without hearing it. So if anyone thinks that this would be a major mistake then please let me know.

Thanks for your time and advice.
