Just for the record :). My new external clock mentioned above was by mistanke set to 3.3 v output which is out of range for firmware 3.32. It is now changed to 1.8v. And it have to have a chance to burn-in - I got it 2 days ago. We will make another listeningsession within some weeks where I...

This is because these units uses the 5v USB power in some way. My former Matrix x-spdif 2 also needed 5 v from USB even though I powered it by a LPSU. You are only able to use the vbus2 with the "A-end" of a USB-cable. https://www.sbooster.com/sbooster-tweaks/vbus2-isolator/

Hi. I have not been as much in zen with my set-up as earlier for some time. Friday I upgraded my DI-20 from v. 3.9 to v. 4.07 and had the same feeling: it has been better. By a sudden impulse I shifted back to firmware v. 3.32 and found this was much better - my set-up played with an effortless...

The USB/SPDIF mentioned below is a Matrix 2 with an Uptone ISO regen and external LPSU (which in all are more expensive than the DI20!). The Gustard U16 with external clock was better than this combination. I have bought a DI20 which is even better. My friend (who also are active in this thread)...

Oh yes the do. Google is your friend ;-) Search for “ audioquest carbon lan” and my cable is hit 1: https://www.futureshop.co.uk/audioquest-cat7-carbon-rj-e-ethernet-cable-custom

Thanks - just the clarification I needed. After approx. 2 months I still can feel what is missing from my short experience with the Gustard U16 with external clock!!! I will probably go for the DI-20 - using a power conditioner I think the DI-20HE will be overkill.

I made an A-B test yesterday between my iMac and Innuos ZEN as source. It took some time to shift back to the iMac, and I thought it sounded pretty OK and wondered if the ZEN was overkill. But shifting back proved I was wrong. Less distance to the music, less flat, voices and bas better defined...

I used to have my music stored on the internal SSD harddisk in my iMac (with good fancontrol) using Audirvana or Roon as player and an USB/SPDIFF converter between the iMac and my dCS Upsampler and DAC. I was quite satisfied with this solution – but shifting to a Innous ZEN MK 3 was a quite...

Hi I had the first Audio GD DI for several years and consider the DI20 or DI20HE. Right now I have another USB/SPDIFF converter, which I have compared with the Gustard U16. My currrent USB/SPDIFF is clearly better than Gustard U16 – but with external clock (oscilloquartz ocxo) the U16...
