To add to Rashmushorn's observations, I have a similar setup (Stagedac, Concerto and Classic) with T1 and LCD2.
Unlike Rashmushorn, I find the LCD2 has great synergy with Stagedac + Concerto and even better with Stagedac + Classic.
I like the T1 less with the Concerto or Classic than with my tube amp. So, two experienced head-fiers are split both ways on the synergies!
I think we can conclude the gear is very competent and it all comes down to preference in the end.
Concerning the Daccord - which I have not heard - I expect it to be similar in character to the Stagedac ("excellent") but better, because of Jan's great added attention to jitter reduction.
