Yes, all sample-rate conversion involves compromises, especially if done in real time. Some converters are measureably superior to others. http://src.infinitewave.ca/ has tests of many software sample rate converters, including SOX 14.2.0. The conversion used for this test is from 96kHz to 44.1 kHz, the opposite of what you're interested in, but the FAQ says "At other sampling rates SRCs may behave differently. However in many cases they actually behave similarly." No measurements of hardware sample rate converters are included, but I, along with Phil and others, think the RCS 2.2X sounds better with 96kHz input than 44.1kHz. I'm currently using a GW Labs DSP between my SB3 and RCS to convert to 96kHz. And, in anticipation of receiving the always-next-month Touch, I'm also doing offline upsampling of everything to 96/24 using iZotope 64-bit SRC, one of the best according to the posted measurements (compare it with SOX at the infinitewave site) and recommendation from a discriminating recording engineer in another group. I have not tried the SOX upsampling since my SB3 can only pass 48/24.
