Hello. Not at a reasonable price. Real upgrade only on R-27 ( MK-2, RE, HE ). I think in the future to change.

Can't remember the details any more, but it might help, read my brief review of the DI20HE reflash: https://www.dastereo.ru/t/usb-konverter-audio-gd-di-20he-chto-za-zver/66288/548?u=igor375375

Оптимальный выход DI20HE через интерфейс I2S.

Maybe someone will be interested in my experience. Comparison of ACSS/XLR interconnects on Audio-GD R-28 ( 2022 ) / Audio-GD A1. ACSS or XLR ? https://www.dastereo.ru/t/czapy-i-konvertory-audio-gd-audio-gd-r-28-r2r11-audio-gd-sa-2-r7he-as-1-i-drugie-strannye-zaklinaniya/31586/2674?u=igor375375

.... 4.076, edit the post. :relaxed:

That's not true. I have the LHY OCK-1, no complaints about sound quality.

I left the firmware version 4.076 as well. :vulcan:

I used this link to update.

Found it online: "ISO - input and output 'masses' are galvanically isolated. GND - input and output masses are galvanically connected directly."

Congratulations. I own an OCK-1 ( 50Ω all outputs ), really like the way it works with the DI20HE, the DAC has no BNC input. For the future the OCK-2 version with impedance switching is very interesting. Looking forward to your impressions, interesting. p.s. please tell me, what is the...

I've spoken to Kingwa- no they don't. And there is a universal 50/75 GUSTARD C2 Clock BNC cable.

DI20HE has an external clock resistance of 50Ω. Designed to connect an external clock, I use the LHY OCK-1 square wave.

Reflashed it to 4.076. The sound is indeed a bit more interesting, perhaps you're right - smoother. I'll stay with 4.076. Thank you.

Thank you. I'll try 4.76.
