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

You should checkout the Bryston page on audiocircle dot com. People have posted their experiences there. Already 35 pages on BDA-3.

I have the bda-3 but I bought it particularly for the DSD and have not heard the predecessors.  From my reading of the forum and Greenhill's review in Stereophile, the 2 and 3 sound similar and the main difference is the HDMI.
  I also have the Mytek Manhatten, which is a clear step up from the BDA 3, and is going for around $3K used, and will play MQA.

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.

@rockyboy, there's a fellow named Pete, who just compared BDA-3 with his BDA-1:

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
