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

Thanks melbguyone!  I'm having a lot of fun rediscovering my old music collection and a whole lot of new stuff on Tidal.  I've already pushed in to my 40's but I'll take what I can get :-) 

I was wondering about break-in so I appreciate the input there as well. Magico apparently  won't comment on the matter for whatever reason.  Hell, then don't even include a manual or setup instructions.
YW Jake. FYI my S5 Mk2’s also didn’t come with a manual, but I contacted Magico who sent me a PDF copy via email. A bit late to read the instructions re: removing  the speakers from the crates, but  helpful & appreciated none the less. Just email Peter Mackay (VP Global sales & Marketing) & he’ll email you the manual. Will PM you his email address.
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.
