As an owner of the MT30, I can state you will not find fault with it. Also, the 1575 pound RRP is quite flexible, and others here have even got the price down to 1150.
The 606 has just been knocked off the top spot by Denon's 1909 receiver, but it is 50 quid dearer, and the 606 still retained its 5 stars.
