Hi chaps,
Just wanted to say thanks so much for your prompt responses. Really kind of you to respond - very insightful.
Guess the question for me now is whether I just go with 818/808, or try and stretch the boat out (a Lot) further to Ultra DAC $.
I would love to hear of anyone here who has heard/owned Ultra DAC vs the above but, I acknowledge I can't be fussy ; it was originally v. expensive and noting analogue only, I understand most M owners here simply can't use it (not for use with DSP's).
Fair point above though that one would assume based on cost alone of the Ultra DAC (vs. 818/808) RRP, gee you would think it would "have" to be better. The quantum of improvement though (for the $) I guess is unknown, and I might just need to be the guinea pig on that if I take that leap.
Thanks again

Andrew
