That is actually what I think too an Audiodiffmaker test would be a good thing to do, iPhone did extensive test on the SB3 and could measure that the outputs was always the same regardless of power-supply used . Or a dbt. I have no detailed info on the Touchs design re internal suplies but if it is similar to SB3 the incomming 5v gets transformed to different other voltages by internal switch-mode supplies anyway. There is a quite real possibility that the switch-mode wallvart can disturb other components, an indirect influence . Many audiophiles own very strange equipment it sensitivity to such things can vary greatly. Then this switch vs linear thing is bogus anyway. there are good and bad powersupplies of both kinds . The original slimdevices SB3 220v Eu supply was very shoddy it even have a burning smell around it ;) and was very feeble and cheap ? Linn and Meridian uses switch-mode supply and are not regarded as shoddy designs So their we have the weakness of our discussions OP may have had (or not) some sucess with his PS he thinks so , he shares his experience. We can read and take notes if we ourselfs should want to get another supply. But from this none can really conclude if it works or not it is especially impossible to tranfer to our own situations . I use an CIA 5v supply I used with my SB3 I let it be in the hifi rack when i got my Touch (my SB3 uses the Touch PS ) Can I recommend it ? I don't know, it is not bad that's what I can be certain of and it does transfer to you, it would be not bad for you too. Technically it looks solid. I could not tell you if you get "blacker blacks" or better "midrange separation" in your hifi with such supply ? -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
