Planning to buy Grimm MU1 streamer

Support
#1

Good morning, I’m a happy owner of a Vivaldi DAC and Vivaldi UPSAMPLER connected to a Mutec REF10 and 2 MC3+USB and planning to buy a Grimm Audio MU1 streamer.
I was told I won’t need the MUTEC Clock and Vivaldi UPSAMPLER anymore because the MU1 must be directly connected to the DAC (how do I’ve to connect them?).
In case I’m left with a spare UPSAMPLER, may I connect it to an EAD DSP9000 pro DAC in my second system ?
I’m confused and, please be kind, let me know your expert opinion on the subject .

HI Gianni, Yes you could.

Connect the AES or SPDIF output from the Upsampler to the EAD AES/SPDIF input - it’ll have to be just a single AES/SPDIF, so the maximum upsampling PCM rate available to the EAD would be 176.4kS/s or 192kS/s, not DXD.

It should otherwise work quite well. :+1:t2:

Hi Anup,
Thank you very much for your suggestion.
I’ll try and let you know.

Nasty question:
What can the Grimm MU1 do better than the Vivaldi Upsampler ?
(Except may be for the optional built in SSD.)

My guess is the Grimm MU1’s Upsampling algorithm framed over AES/EBU streams imparts a different flavour to sound quality - not more accurate or any better, just different that some people subjectively prefer.

May be.
However, upsampling is limited to single AES (i.e. 192kHz), no DXD, no DSD.
But then the price is only about half that of a Vivaldi Upsampler.
