Ok but why ? Was it you that always had a constant upsamling going on or was it some other member . Or is t to defeat potential intersample overs ? I have for the last months tried to find out if I can produce any awerse of positive effect by not running the volume on the Touch at 100% when using its digital out to my Meridian system , just for these intersample overs . My processor is designed in 2004 so circuits for upsample may not be the most modern ( it samples everything to 24/96 before applying volume and DRC , dithered volume ;) ). But it I have not done the most rigorous testing so it's still a null result I'm yet to hear any difference on any recording . Nb this will only manifest if a recording is such that it would provoke this issue in the filter and if my over sample filter is sensitive to this . Another effect , I'm now also personally convinced that the squeezeboxes volume control is transparent for human listeners at least at the higher volume settings regardless of how it's actually done in the software :) depending on total system gain it's probably fine all the way down ! on CD material the "problem" of no dither will probably only manifest when reaching bit 16 of 24 that's probably at a fairly low volume . ( cd stuff is padded with 8 zero bits by The player to make it 24 bit ). I'm ofcourse open to be totally wrong , that would not be the first time ! Anyone with more insight on the squeezeboxes volume control . -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
