Better DAC or better Streamer

I believe the Nagra streamer is the same as the PlayBack Designs streamer that I had. The low end one for $3k. The Nagra DAC is also a PBD DAC design but with different boards than in the PBD DACs Andreas Koch of PBD mentioned the DACs in an interview and I read something about the stream online.

DAC for sure. There was someone comparing my $3k PBD streamer to the $13k or $20k PBD streamer and they could not tell the difference. Most likely because fibre was involved. PLINK in the PBD case but you can use something like a OpticalRendu for similar non-proprietary results.

Spend $2k less and get the PBD lower end streamer which seems like the same as the Nagra. Mostly likely because Nagra licensed it from PBD.

A fibre cable did not sound the same with 2 of 3 fibre streamers that I had at the same time. The Lumin X1 and OpticalRendu were fibre optical, and the Playback Designs was SPDIF in my test (though it supported fibre). All were great but very different sounding.
