Sound quality of a Bryston BDA-1 vs the BDA-2 or BDA-3


Been happy with my Bryston BDA-1, but wondering if the BDA-2 or BDA-3 have improved sound quality over the BDA-1.  Can any owners of Bryston BDAs share their listening experiences? I have no interest in DSD.  (fyi - using a Bryston BDP-1 with cd library loaded on thumb drives)

Went to Audiocircle and saw comment from James Tanner (Bryston engineer) that the SQ of 2 and 3 was same, although a few folks disagreed.  
Not sure I fully understand and appreciate MQA, DSD and HDMI capabilities. I have no SACD player or SACDs and have no desire to play video. However if DSD and MQA are game changers and available now or in future via downloads, I will have to reconsider.

Appreciate you bringing that to my attention. 
Think I want to start looking for a used BDA-3 or Manhattan or even Brooklyn. 
Thanks again
