Sorry to be late in responding - but - I am using a Rowland Continuum 500 integrated amp on a pair of Eggleston Andra II speakers and the results are excellent. Clean, pure, good soundstaging, great depth, plenty of power (to say the least).
I am very pleased with this combination - the Andras and Rowland are in my "second system" - my main system is Avalon Eidolons with Spectral electronics - and I find nothing whatsoever to complain about with the Rowland integrated in comparison with the Spectral.
I have tried many, many integrated amps and prefer the Rowland over all. The last two I tried - Moon I-7 sounded wonderful but was a little underpowered for the Andra II speakers. The Gamut DI-150 was the most beautiful piece of stereo gear I've ever owned and sounded absolutely fantastic, but I sold it in favor of the Rowland because of its lack of a balance control. Seating in my makeshift listening room (for the second system) requires a slight shift in the left to right balance - otherwise, I would have kept the Gamut - although I am not sure it sounded any better than the Rowland.
