Thank you very much for the detailed answer. I'm afraid I don't have budget for 2 separate devices and I use only headphones, no speakers whatsoever. Well, since there is no mk3 on the horizon, I'll buy R2R-11 mk2. From what I understand it's still a good choice for headphone usage in its price...

Yes, this model is now at this page http://audio-gd.com/Discontinued.htm It's still in stock and it's still possible to buy it but it's a bit concerning for me.

It seems R2R-11 mk2 was discontinued. Are they cooking mk3 version or is there another reason? Is R2R-11 mk2 still a good choice now or is there something superior for the same money? Or similar in specs but cheaper? Wanted to join r2r club, read a lot of glowing reviews for this model, but...
