Re: [SlimDevices: Touch] Linear Power Supplies
Quote from the producer: Well the UltraCap LPS-1 is unique in being an extremely low impedance unit with cascaded ultra-low-noise (4uV rms from 10Hz to 100kHz) regulators. And most importantly, as a bank alternating supply whose active output is 100% isolated from the charging side, it completely blocks the path of AC leakage currents, a important part of removing whatever it is powering from the "leakage loop" in that part of one's system (ALL audio systems have leakage loops happening between components with power supplies). The LPS-1 is a bit like a battery supply in this respect--without the several disadvantages of batteries.

Download LMS 7.9 from here: http://downloads.slimdevices.com/nightly/?ver=7.9 2. Login to your account on mysqueezebox.com My guess is that option 2 is your present configuration. Right ? If you have a local content you like to play, you have to do option 1 If you have an iPad (or iPhone), I can recomend iPeng app to control your Touch.

I'm getting the message "no content available". But the old Wimp works. The Tidal interface that used to be Wimp is also working, but as the menues offered are very limited I'm not normally using that option any more.
