I just wanted to let you know that I could not be any more pleased with my ST 1000 Mk2. It current has about 250 continuous hours on it and is such a pleasure to listen to. It does not sound like a solid state amp, it does not sound like a tube amp. It simply sounds like music and that is the whole point. It has so much reserve power and lets the music breath. I know it is possible for it to get even better over time but I just can't imagine how that is even possible. It runs so amazingly cool too. I must admit I was a little hesitant to trust a Class D amplifier in my system. At this point I don't even think about the engineering of the unit hearing is believing. Thanks for a worthy companion for my Dac2 DSD se and my B&W Matrix 800 monsters they sound way larger than their 6 foot three inch height and their 250 lbs weight each. Keep up the great work.
