My system is only circa $1,000- and the Power One external linear regulated power supply made my jaw drop. The most notable improvement for me was bass response. I had the hardest time placing my sub, and always had the gain on the sub amp to max. With the external supply there is some headroom for the sub amp, and bass is placed where the recording dictates, not where the sub is sitting. The soundstage itself became the whole front wall, rather than the area directly surrounding the mains. I can't locate my mains with my eyes closed anymore, on decent recordings anyway. Sibilance was reduced to the point of being able to enjoy cd's I had written off, but with no noticable loss of high frequency extension. Audience clapping used to sound like it was coming from 'onstage'. Now it sounds like the audience is behind the performers on some albums. As you can tell, I can't say enough about the improvement. The differences between power supplies are more dramatic than when I went from a cheap Sony DVD player to the Squeezebox analog out. I spent eight dollars on the surplus power supply, so I have no reason to *justify* my purchase. I use the analog output unmodded, so there is still tons of room for improvement. I'm even starting to question my desire for an external DAC. However, I can't see how one would worry about a single switching supply on your mains when there are tons of other devices in most homes that run on switching supplies. Perhaps it would be different if you had a dedicated circuit and ground for the system? -- Skunk ------------------------------------------------------------------------ Skunk's Profile: http://forums.slimdevices.com/member.php?userid=2685 View this thread: http://forums.slimdevices.com/showthread.php?t=21175 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
