The dac is great. Not tda1541aDC class but what is?
I don't have a ESS dac to compair it with, all my stuff is old.
Used to use airport express optical out to a Sony es MD DECK as a dac
Female vocals are fab, it has coincided with my renascence for Sade's discography (16bit FLACs then now on 24/96 vinyl FLAC's )
I do feel that the metal coating on the drivers has lead to my uptake of more music this year.
The bass holds better, compaired to the "saffire coated" 40mm drivers on the cd900, an the larger 50mm drivers on the 7520 can take a louder input but the 50mm LCP drivers sometimes sound they have "break up"
Where as the metal coated drivers on my z7 an 1aDAC don't have this perceived "break up"
For what I got them for (£150ish $220ish) they are def worth very penny.
I always liked how Sony stuff gets discounted so aggressively
Heck I got my walkman a15 for £99 ($150) day after Xmas
