Thanks, they most certainly do. I've said time and time again and will continue to do so, the LCD3 and HD800 are both excellent to me with this setup.
Sorry for the late response. Before I say anything, some headline notes for readers to take into account before reading my feedback.
1.I didn't compare the two DAC's side by side so my impressions are separated by a week or two
2.The source both times was a laptop running USB to the DACs. The BDA-2 is supposed to have a better USB implementation (Async 24/192). I never tried any of the other inputs. USB cable used was stock quality both times, nothing fancy
3.Both DACs were only demo'd with the BHA-1 via cheapish Audio GD XLR interconnects and LCD3s on Audeze stock 4pin XLR cable. Power cables were all stock
4.If you believe in burn in, all the gear is less than 50 hours old so do take that into account
5.I am not an educated/highly experienced audiophile and am barely passing on my subjective, relatively uneducated opinion on what I believe I heard
Given the above, please take my opinions with a grain of salt.
What I'm reasonably confident I heard
Bass/lower frequencies seem better defined and controlled
Mids seem a little pushed further back as the overall soundstage is improved from both a width and depth perspective
Separation of instruments is improved
What I'm not entirely sure of
The highs extend further with better definition
A darker background (have seen some graphs somewhere out there showing that the BDA-2 measures very well in terms of having a silent background)
Given all the parameters surrounding my opinion, I believe the BDA-2 is an improvement on the BDA-1. I wouldn't say that the difference is night and day but at the same time, please remember that the BDA-2 is "only" $200 or so more than the BDA-1; IMO, a no brainer if you plan to use USB or value DSD support in future. If you own LCD3 or HD800 headphones and use a PC/laptop as your primary playback device, I very highly recommend this Bryston stack.
