Lots of variables. Depends on the electronics. There will be a sonic difference just in using different cables. In my experience comparing same brands of cables (1m lengths) RCA is just fine, no benefit from XLR balanced cables.
RCA vs XLR which would say is the BEST?????
Here is the system:
1. Merlin TSM-M (right/center/left)
2. Axiom QS 8 rear channels (right/left)
3. (2) Earthquake Supernovas MKIV
4. Satori Shotgun Bi-Wire Speaker Cable (right/center/left)
5. Arcam DV 27 (no xlr connection only coax/optical/analog)
6. Bryston SP-1 Pre/Pro (coming with XLR connections)
7. Bryston 9BST amp (coming with XLR connections)
Now I need to connect the SP-1 to the 9BST so do I use RCAs or XLRs? I can do the in either .5 or 1 meter. I have enough RCAs to do the job now and I would have to buy the XLRs. I only want to do this once (right how many times have I said that in this hobby) so your advice will be welcomed. Which should it be?????
