Need a power amp for a pair of ATC SCM 11's


Hi,
I'm new to this forum, but have been lurking a good while and finally I'm in need of some sage advice!
I'm in the process of purchasing a pair of ATC SCM 11's and I can't figure out what the best power amp would be.
The preamp is an RME ADI 2 DAC, which I love and is so customisable, so I'm kinda commited on that front.

I've seen recommendations here before for the Quad 909, there's a few of them on ebay at decent prices.
Another amp I've seen recommended is the  Wyred 4 Sound ST-500 mkII. 

Should I push the boat and spend the extra on the Wyred 4 Sound, or find a nice bargain on the Quad 909?

Any other recommendations or advice is extremely welcome!

Thanks a lot :-)

ATC is very revealing and inefficient from what I've heard. My current class d sounds absolutely great in 2 out of 3 of my speakers. My current mains which are very revealing and also happen to be the least efficient not as much. AB much better..
Also was running a Lyngdorf TDIA 2170 last year which I hold in high esteem as far as class d amps go. Sounded phenominal with efficient speakers. 4 ohm low efficiency not so much.  Ymmv.
 Had a Wyred dac one time but never one of their amps.
