Integrated Amp to match with Magico A3


Have just ordered a pair of Magico A3, and looking for integrated amplifier to pair with it. As I heard once which had a very disappointing result to pair with Gryphon 300 in a local Hifi show in Hong Kong. Reallly looking for recommendations on matching amplifier. Planned to get a Marantz PM-10, but worried that the single box may not be powerful enough to push the A3. On the other side, some said Hegel H360 with 4000+ damping factor may suit even better.

thank you in advance

Power requirements for the A3 are 50-300 watts. I'd look at the Perreaux 255i and the Luxman 509x. 
I think 300 is just a minimum reference. Since the construction and design of the driver are rather demanding, I think high damping factor amplifier is what I think required.
I evaluated the S5's in my search for a new pair of speakers.  My local Magico dealer had the S5's attached to a powerful solid state amp with an extremely high damping factor, when pushed hard, the S5's "came to life".  When their "high end room" became available, the moved the S5's into that room and attached it to a tube power amp, and the speakers sounded MUCH better, had more bass, smoother highs and didn't seem to be driven as hard (as with the solid state amp) to "come to life".
Go for a Rogers EHF 200...Lifetime warranty, so there is the extra pressure to stay alive. Another note...a pic from someplace of a Magico factory tour showed a QSC GX3 300 watts PS pro power amp on a shelf...I wonder what they use that thing for. I have one of those for live stuff I do, and it's amazing...cost less than 300 bucks new.
