Since my Cyrus CD8X stopped working the other day I have been using my pioneer dv-565A as a transport fed into the DACXP using a cheap toslink cable. The CD8X was connected using a Chord Signature digital so there is no comparison in the qualiy of cabling. The CD8X has a PSXR attached to it too.
The DVD as a transport sounds flat and lifeless and there is so much detail missing from the music. Dont get me wrong, it sounds quite good, but not a patch on the using the CD8X as a transport, cables aside.
If you are planning on using a DVD player as a transport, audition well, as for the pioneer being one of the best transports around, my ears tell me that is complete tosh.
