Peter, there is no need to change the supply on the Touch. I have measured both the analogue and digital outputs (via a DAC) and there is no measurable difference at all with either between the stock PSU and a very expensive medical grade 5A Linear supply. The only reason for changing the supply would be if you had an AM radio (?) nearby, as some of them can be susceptible to the RF. However, all other equipment should have adequate AM rejection. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
