I have two iPods, one is a 4th gen Touch, the other a 6.5 gen Classic (120gb)
I have a Fiio E01, a iBasso D-0 and soon a Sony PHA-1
I believe that both the iPods can't go beyond 16-bit 48kHz playback, while iPads can do 24/96.
The PHA-1 can go, when connected to an iDevice, up to 24/48, but from an iPod will never get that, just 16/48.
My iPod touch, and rockboxed Classic can play alacs and flacs coded beyond the 16/48 limit, can feed 24/192 and it plays.
On the Touch things sound ok, I think, however on the rockboxed Classic 24/192 flacs start hissing.
Now, because I am going to use the PHA-1 with the Classic, I have to get back to the original Apple firmware, and therefore to alacs.
Question One. Will there be any difference in SQ between;
"Convert flacs, like f.i 24/96 to 16/48 alacs beforehand" or "Let the re-sampling be done by the iPod (classic) to 16/48" ?? (I guess that happens)
(for the rockboxed classic it surely is better to convert to 16/48 beforehand,as it seems)
Question Two. Is there a difference in quality of the various down samplers, or is it a simple algorithm nobody can make mistakes with?
I now use TAudioConverter (easy to change bitrates/sampling freq) or foobar with qaac.
Thanks for listening!
