5.1 connection vs coax


I have both 5.1 analog input and coax output on my pioneer elite dvd player and 5.1 input on my B&K reference 30 preamp.I dont know which connection would give me better sound.Whats your opinion??

thank you for the advise.I am going to purchase some Signal cable analog 2 cables next week and give it a try.
Kal is right. I have Denon 5910ci and a McIntosh MX135 that I pass two channels thru a LS26. And I find that on certain codecs I get better diminsion on 6 channel input and others I do better using the MX135 processor. I would use both if possible. On SACD and DVD-A 6 channel is best hands down.
Try them both. It will come down to two issues. First, which device has better bass management (if needed) and, second, which device has better D/A conversion.
