Pete, you lost me :wink:
what was the test setup?
Vivaldi ----?-----Router?

Interesting
In your case, I believe you’re using a Melco?

23

Currently router feeds a Melco S100 switch to Melco N5. PS for the switch is Plixir Elite and the DC wire is Plixir’s reference, surprising how worthwhile ( I have the standard cable here too). Various Melco cables used but NOT to Vivaldi which is Belden Catsnake CAT5E UTP.

As I can find no technical justification for any of this ( except UTP) I regard it as irrational. Very effective subjectively but irrational.

Thanks Pete,
so your setup is Vivaldi—USB—Melco N5—S100----Router?
Do you use a clock as well?

25

Yes, the dCS end of things is Vivaldi DAC, Upsampler , Wordclock and Rossini Transport . I use a pre-amp which is EAR Yoshino 868 PL with NOS Tungsram tubes.

did you try to attach the Melco direct to Vivaldi DAC without going through the upsampler?

27

No as I use Melco in its role as NAS not as a streamer, that requires network connection and a streaming board.

Not quite. I so not use USB. Connection from Melco to Vivaldi is network. As I said elsewhere in this thread I do not use Melco as a streamer but as NAS.

Pete,

I found this post about using your Melco for a NAS. I was wondering if you ever tried using a non dCS network streamer such as an Aurender N20 instead of a Vivaldi Upsampler?

Thanks,
Brian …

No, as gains were made moving to Melco N5 as NAS and improved LPS to S100 rather than attending to Vivaldi streaming. It satisfies me to the extent that I have no interest in further changes.

Edit: The improvement noted was to local files , streaming from Qobuz and internet radio where N5 acts as a pass through for the latter two .No idea why though as it should not make a difference.
