Thanks for the feedback. With no load, I measured the wall wart's voltage at 5.18vdc.
I've build/modified a number of power supplies, both linear and SMPS, and my experience has been that they do improve after being powered up for 48 hours or more. For example, the makers of Black Gate capacitors feel performance improves after 30 hours of use, see: http://www.blackgate.jp/english.htm My linear psu doesn't run "hot." If I put my ear right next to my linear psu, I can hear some noise, but I can't hear anything in my very quiet dedicated listening room's listening position. You can also hear noise, if you place your ear right next to the stock wall wart. I'll bet you can also hear noise with your ear right next to your Arcam amp, or any other piece of electronics that has a power supply linear or SMPS. I agree that some people may not hear any improve when they try an off the shelf linear psu. Be well. mick_w;171641 Wrote: > Yes I did test the voltage (spot on 5V), yes I did wire the unit > correctly, and yes I did have it running for over 4 weeks constantly > before I tried the A/B test. > > (I don't want to start a flame either, but running in a power supply > shouldn't really make any difference if its working correctly to start > with...) > > Like I've said above, I couldn't tell the difference even though I > really wanted to believe the linear PS was better.
