Thank you all for your responses!
@ Brf: I like the simplicity to and would go for both upgrading tubes and caps and resistors. Cary offer some upgrades - have you tried these? http://www.caryaudio.com/upgrades.html
@ Martykl: Good point but I prefer the 845 tube with my Avantgarde speakers and I will not be changing to other speakers for years - only upgrade within the Avantgarde Duo line.
@ Lewhite: I have the dCS Debussy dac and use the 6V output which works fine with the 805C. But plans are to get my hands on a Cary SLP 05 :-)
