I own the Callisto and Cary products seem to be a great match for GMA. I use a Rocket 88R and I am very happy with the results. The Europa should sing in the same manner.
I have used europas with a carver lightstar, aragon palladiums, and an MF trivista integrated, and they all worked well. The carver had the most bass, the MF was the most detailed, and the aragon was in between. I think they are pretty forgiving, just don't underpower them.
Buy an Art Sla 1 on Ebay for $160. Put a decent power cord on it and some decent footers. This Art will floor you. Yes, I said $160 new. I own three of them and love them. I also own a Mcintosh 402 and the Art is not as good. Ha! But it not far behind. Nor was it far behind some other big buc amps I have owned.
Most interesting little amp! Feel free to email me if you want to talk on it as most folks will just dismiss it on price only. To bad! 100 watts per channel with dual volume pots and XLR's only. Can use a 1/4 inch to RCA adaptor also.
