(I helped my friend burn in the unit lol)
-How kind and sacrificing of You (lol!).
No, I don't use DI20HE and MC3 in serial. I have too much gears.. I let the DI20HE feed the R7, I2S via HDMI. The MC3+USB feed the TDA dac via AES/EBU and also spdif to R7. My Gustard U16 feeds the NFB27.77 via I2S/HDMI they all via Master 1 (pre) and via Gradient active XO to Master 3 (mid/treble Quad ESL) and 2 x Master 2's (Bass <110Hz, Gradient SW63's)
-Confusing? Not really...I don't play it all at once. One positive thing with both the DI and the MC3 is the multiple outputs simultaneously active.. You can crossfeed the dacs with the same stream so it is easy to alter and compare

I thought you have a regen iso before your di-20.

on another note I would appreciate a full report on the mutec clock. These oxcos increase transparency and detail noticably but the sound is thinner and perhaps a bit clinical. I understand the ref10 is very full sounding, which is to my liking and I am curious if the 120 is also full bodied.
I will report my finding here in this thread.

FWIW, Kingwa has just announced a new beta firmware for the DI-20 in audio-gd Chinese forum. One can email Kingwa asking for it.

I don't own the DI-20.

So, I ordered a Mutec Ref 10 too. It will feed DI-20HE and R7-HE 2020 together. Any new consideration about maturation? What kind of 50 ohm cables are you using?
Congratulations. For the moment I use a pair of mililtary spec. (RG223 from 1966) 1.0m. They are TRUE spec but a bit too long. I will replace them later with shorter ones (~0,5m). A RG400 based cable with true 50 Ohm connectors should be fine. Cybershaft sells semi rigid RG402-based cables with individual measure graphs with each cable.
For 75 Ohm I have Mutec's own 0,5m cable.

The manual recommends two weeks but I expect a month to be fully matured and stabilized.

Could anybody help me to confirm this: I have an old (but good sounding) Wadia 15 DAC with only BNC coaxial and AES port, and support at maximum 48khz sampling rate.
Can it run smoothly with DI-20? And can I disable the DSD upsampling function of the DI-20?
Thank you!

Hi there.
Your dac will work flawlessly with DI-20, just using a part of its immense potentialities.
One thing has to be remarked: DI-20 doesn't upsample files in any manner. It just "unmount" and "rebuild" in the best way possible usb or AES signals feeding it, either pcm or dsd independently. So, if you use just pcm in, you'll have just pcm out to your dac whatever output connector you need to use.

Here's the DI20HE with one of the earliest r2r7. 2ft Belden HDMI. No clocks. Passive pre is connected to the amps over 30yo Japanese single ended litz interconnects (Audio Tekne ARC-500). The mics are getting 48v from a single USB3 connection. I ordered something I can power from an LPS tap for my next video.


Next up is my evening walk and Quarantinis!
