Danlib, if you hear differences with different transports then one or all of them are bad transports. The bits on the CD are precise (most of the time), and the transport's job is to read and stream them accurately. If they do, all will sound the same. If not, then one or all are introducing random errors into the stream which cannot produce a predicatable audible change. The DAC decides what to do with the erroneous information and produces the sound. There are some common effects with streams that are specifically faster or slower than 44.1 khz, but really, why in the world would this be desirable when the music was encoded with precision at the specified frequency?
When you find several transports that sound the same on your DAC, its likely that they're good transports and are producing accurate streams. Hearing differences only indicates that problems exist. The same argument applies to cables, but that's another discussion.
