I have the T5p and Daccord and have used them together, but I've never done A/B comparisons with another DAC. My general impression is that while the Daccord is a bit less than ideal for the LCD-2.1 (especially when using the Lyr, smooth + smooth + smooth ends up being too much of a good thing IMO), it works very well with the T5p. FYI, I use an M^3 amp when listening to the T5p on this setup, which is a very competent amp, but I sometimes think might be just a slight touch on the dark side.
The generally smooth and inviting sounds signature of the Daccord seems like it would lend itself well to any highly resolving, treble-tipped cans-- and the T5p fits snugly into that category IME. Wish I had some more detailed impressions for you, but this is all I have at the moment. If you have any specific questions, let me know and I'll try to answer them!
