I have been running a SB3 via co-ax into a Topping E30 DAC with no issues. over the weekend I decided to do a comparison with a Touch running co-ax into the E30 and that worked well. Howver I notice the E30 'auto power off' function does not work with the Touch in standby mode but it does with the SB3 and I an't think of any setting that should be changed to make it so. Anyone with a Touch and E30 experienced the problem or am I missing something obvious?

It is as though the Touch is still outputting a signal over co-ax even when in standby (clock).
