Just connected the st-10 to the dac-10, must say my biggest fear, (harshness and brightness), is ABSENT, what a relief. It's just a touch edgy, if you know what I mean. But it's doing a good job now, thanks to Mr. Jye, the dealer for running it in for me. He has clocked about 50 hours, which normally will take me months. Let's give it more time and see if it improves. Thanks to all that encouraged me on.
