New CD Player or Existing CD Player as Transport to a DAC?

I have a Bryston BCD-1 and Bryston just came out with the BCD-3 for $3500.00

So my question is: would I be getting a better listening experience if I sell the BCD-1 and buy the BCD-3.
Or would the playback be just as good or better, if I kept the BCD-1 for a transport and bought a new DAC like a Benchmark, Berkeley Audio or Mytek and connected my Bryston to that?

Thank  you for reading this.
