Speakers for string Quartets

Before I gave up listening to speakers and going on to headphones I used to Have ATC SCM 40 speakers and they were ideal for string quartets. I truly love chamber music with Quartets being my bread and butter and The ATC's being absolutely brilliant being a very accurate speaker and able to handle any amp put to them.  

I have been a musician nearly all my life and also a HI Fi nut. I am very into string quartets and have had various ensembles to play them back. My first real forage into chamber music playback was a pair of Stacked Quad ESL 57s. They were much more dynamic than a standard pair of speakers and that midrange was magical. They certainly were no good when they were trolling the depths of the cello ( Fried a few panels and cost a good few Quid.) I got rid of the quads and then went to Rogers LS35As along with a REL sub which was much more successful albeit the Rogers needed lots of watts to give a decent sound and perspective. After a few years with that setup I then scraped up enough to purchase a pair of ATC SCM40 speakers and that was when happiness set in at last the cello shone. To put a bit of perspective on things I am very acquainted with live string quartet playing having gone to the Edinburgh festivals for 40 years and heard many many quartets, Amadeus, Alban Berg, Edinburgh, Tacacs, and many more and the ATC's seemed to capture that special sound of quartets and also the intimacy of them.
