NEED HELP WITH DAC UPGRADE

you might try out the DAQX item before moving away from Bryston - this looks like nirvana to a lot of folks and makes good engineering sense besides

Opps! typo - should be DEQX

thread with little real info here:
https://forum.audiogon.com/discussions/is-deqx-a-game-changer

their site:
http://www.deqx.com/

some people have complained about the manual & setup - Google deqxpert bad reviews

maybe wait for the next version(?) - I think it might be the next place to toss $5k at in home audio, tho it is not clear why it cannot be done for $500 with some mass production...

I really like the solid warranty on all Bryston products, but with limited ability to audition you will have problems.

Some mail order places allow audition & return.  Oppo, which will have a new DAC out soon, is one.

Also start looking at mail order retailers who allow returns.
