As long as you don't get drop outs any of them are fast enough and the quality will be the same if the file can be read .
If there is a difference ( which is unlikely ) the explanation must be something else , power demand on the 5v for USB , noise from the USB drive . Noise from the USB drive PSU ? That effects the hifi as a whole ? If the Touch can't power the usb drive you get failed scans and possibly buffer underuns when playing ( that's a difference it's gets totally silent ) . But before hunting for an explanation or test listening SD cards ? Do a reality check and do an ab or abx listening test or if you are technically skilled an audio diffmaker test ( very cool software if one has a good soundcard ,it enables you to make high quality measurements at home ) with an abx test you can determine if any one can hear it at all, with the diffmaker test ( or any other good measurement ) you can find if it's difference at all below the threshold of human hearing . The AB or ABX listening test will remove the perceptional bias , the "in the head factor" . In can be tricky to set up maybe you have to use two Touches or make a symlink on one of the media IF the onboard server does not crash when two media are inserted :) a simple not super scientific AB test is to make a playlist with 10 of each test file and then press shuffle . -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
