Ceejay- I thought about this some more and came up with a way to test for this. If the stock power supply is throwing off RF that effects the other components, disconnecting the power supply while listening to the other SB should reveal a difference. To test this, I had played my favorite test track, Hotel California, through the SB3/Elpac/Lavry and asked my wife to randomly unplug and then plug in the power supply from the wall. We did this ten times and I could not tell the difference in any test. To go one step further, knowing that I have very clean power and a dead black background I played a test track of all zeros representing silence. I turned the volume up all the way and as usual I heard nothing, absolutely nothing. I plugged in the stock SB power supply and I heard no change. Thinking about this some more I wondered if the RF interference might be a problem for some systems and not for others. I run balanced from the DAC to the preamp to the amp. Maybe my system is immune? Then I remembered that I'm running standard interconnects from the SB/Elpac to the preamp and I was testing the digital black with the Lavry. So, I switched input and repeated the test. Still however, no difference. At least on my system, the power supply makes no difference. -Ben -- Ben Diss 'SB3' (http://www.slimdevices.com/pi_squeezebox.html) -> 'Lavry DA10' (http://www.lavryengineering.com/productspage_da_10.html) -> 'BAT VK-31SE' (http://www.balanced.com/products/line/Vk-31SE/index.html) -> 'Halo A21' (http://www.parasound.com/halo/a21.php) -> 'B&W 803D' (http://www.bwspeakers.com/index.cfm/fuseaction/products.models/label/Model%20803D) ------------------------------------------------------------------------ Ben Diss's Profile: http://forums.slimdevices.com/member.php?userid=4289 View this thread: http://forums.slimdevices.com/showthread.php?t=33986 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
