Move on from my Bryston BDA-1?


Given the advancement in DAC technology would I achieve a noticeable (started to say significant) improvement in audible performance by upgrading from my current (but early generation) Bryston BDA-1? I am hesitate on the assumption that the internals of the Bryston (e.g., power supplies, output stage) are still hi-grade but understand the CS-4398 chips have been surpassed. I should mention in the system I stream from a Bluesound Node 2i (and in another use an identical streamer with a Topping D90 DAC).

Interesting comment about the R-2R style docs. For the cost I am  interested in the Ares II which seems to be well reviewed. Regarding the comments regarding tube or tube-like sonic quality, when reviewed against other similarly priced DACs the Ares seems to be the most 'full blossomed", i.e. less analytical.
Be interesting to see what a BDP-1 would sound like as the streamer using the MPD.  You can pick those up cheap now.
I think you may easily find a DAC that provides a significant improvement to the sound quality, depending on what it is you listen to and prioritize when listening to music. The BDA-3 would be a big improvement over the BDA-1, in my personal opinion. But there are lots of other DACs out there that you may prefer.

I will get this delivered tomorrow. I will compare this to my 2 existing DACs, Benchmark DAC3B and Audio Mirror Tubadour III SE (mentioned above). The review above says it is a step up from the DAC3B which I am sure is better than the Bryston BDA-1.
