I just got my r2r 11. I played music through the toslink input outputting to my he-560. Good open sound but not much sub-bass control yet. A little too thin as well. Then i tried the amanero input, with about the same results. Needs some burning obviously, But then... I decided to test the rca input using a Haliday Bridge i had in hand, which is fully burned-in. The sound was holly f. cow good, bass and mids and highs and everything. The amanero needs to burn, but i am far from being sure it will beat the Bridge once burning is completed. The Bridge sounds so full. And it makes my he-560 sing! Just love the sound. How a unit costing as little as the r2r 11 can sound so good is beyond me. The amp is more than adequate for the he-560 and it will sound, combined to the he-560, like whatever the dac will play. And with the Bridge, to use a euphemism, i does play.
