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

Note that Alon Wolf recently noted they primarily listen to "Red Book" level digital sources at Magico. 
May want to consider McIntosh MA9000. A true heavyweight and it will hold it's re-sale value very well. 
Check out the Wyred for Sound integrated STI 500 or 1000. We have separates and they are outstanding. High damp factor, pure liquid sound, nothing quite like it. More addicting than good food or beer. Soundstage....check, Bass energy tight and very extended, way more than many much larger systems get....check,  Awesome performance and STILL pay the rent. Check mate. The STI 1000 I believe the last time I checked is a TOTAL sleeper at $2499. You can definitely spend way more and get so much less IMHO
Sinewareon is correct in a dealer showroom with over 10 ft ceilings and like 17 x 23 room avg watts is 6 on Sonus Faber speakers.
