I'm aware of the different DACs Sabre vs. Wolfson. I'm more partial to the Sabre DACs but more importantly the Amp cards in there play a big role. What card do you have in yours? When I had the 901 I was using the Balanced card.yes 802s anytime. but if you like about details with 802s 8740 is not able to compete with 901, with the mod to 8741 it won even 901s in term of detail while preserving good organic sound sig.
watch out 802 & 802s are total diff beast, dont just look at the dac
I also want to thank you for all your input!
