Hi, although I started this post already in another forum I´m really curious if some of you have (or had) the same problem I´m currently facing with my Touch (which I bought a couple of months ago).
While I was testing some speaker cables I recognized some annoying supply noise. I didn´t recognized this earlier due to the reason - my explanation - a) that I was not focussing on the music and/or b) I wasn´t listening to a similiar song before. So this annoying "phenomenon" occured when I was listening to Susanne Sundfør´s song "Diamond" (from the Silicon Veil Album) which starts only with her voice. The first seconds of the song are silent (and the noise is audible even at lower volume) and then she starts singing...no instrument at that time being. And that was the point when I first recognized the noise. And this noise gets more intense the more I turn on the volume. Even when no song is played the noise is audible and gets more audible dependant on the volume. So I checked if there is the same noise with the other devices on my HiFi unit which consists of the following devices: Pre-amp: Proton AP1000 Amp: Proton D1200 CD player: Pioneer PD 7500 (Source "CD" at the pre-amp) Speaker: KEF Q5 All songs are stored on a NAS which is connected to a gigabit switch. Touch (Source "Tape 2") and Pioneer are conneced via Analog RCA cable to the pre-amp. In addtion to the above mentioned devices a PS3 as well as a Sat receiver are connected to the pre-amp, too (also with Analog RCA). The noise is audible with the Sat receiver (Source "Tuner at the pre-amp) as well as with the PS 3 (Source "Video"; even if the PS 3 is "off"). But the noise is not as "loud" as with the Touch. Interesting thing is that I don´t hear any noise with the CD. And it doesn´t matter if the CD player is off, on and/or playing some music. Therefore I tried to hook the Touch with the CD source but with no change for the better. Switching the Touch to "Tape 1" and/or a 180 degree turn of the Touch´s power plug in the multiple socket outlet didn´t change anything either. Before I started the cable testing the guy from the HiFi store recommended a better power stripe than the one I bought several weeks ago (it´s an APC outlet with surge protector). Maybe this could be the solution for getting rid of the supply noise?? But we´ll see. Due to the fact that the noise with the Touch is more audible that with the other two devices (PS3 & Sat receiver) I´m wondering if this is related to the Touch´s power supply and/or the Analog outs? Would any optional power supply be beneficial? Or in addition to that the purchase of an external DAC which is then connected to the touch via optical out?? Hmmm.....don´t know....based on your acknowledge what would you recommend?
