If a voltage range is given, it usually implies a poorly regulated (or unregulated) output, and/or insufficient power (an inability to supply a higher current at the same voltage). You shouldn't get one which will not supply at least 1.5A at 5V. You can get one which supplies any amount of current in excess of this, the only downside being that the more current it can supply, the bigger (and more expensive) a linear PSU will be. > > Is linear or Switch mode the way to go?

A new PSU is arguably only better if you can 'hear' the difference.. so do a blind test and see if you can! This rather begs the question of why you are looking to buy a new power supply anyway? > > I have found a few labatory power supplies that appear suitable but > these are between 30-40% of the cost of the SB itself, perhaps second > hand is an option here I expect these have a well regulated supply I > notice one has Ripple & Noise <1mVrms , which my very limited expertise > seems good. It is good, and that's what you pay for. You probably won't find even a cheap one for less that 50 AUD. -- Khuli http://www.last.fm/user/khuli ------------------------------------------------------------------------ Khuli's Profile: http://forums.slimdevices.com/member.php?userid=851 View this thread: http://forums.slimdevices.com/showthread.php?t=25446 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
