Tried the T2 firmware upgrade on an iMac running the older MacOS El Capitan and it failed after I dragged the file into Terminal and pressed Enter. Thought it had bricked the DAC initially but it was fine after unplugging it and plugging it back in. I got some errors in Terminal but assume it failed before the upgrade had properly started. Will try the upgrade on my Windows PC when I’m feeling brave enough.

FWIW I did the upgrade on my T2 with a Windows 10 laptop and it worked exactly as advertised.

I tried both, the update process worked perfectly, only extra and important step needed for PC is to disable WINDOWS SIGNED DRIVER ENFORCEMENT. My problem is updated T+ is not compatible with my version of Iris DDC via I2S connection. I had to revert back to V1.0 while waiting for Vinshine to provide fw update for the Iris DDCTried the T2 firmware upgrade on an iMac running the older MacOS El Capitan and it failed after I dragged the file into Terminal and pressed Enter.

Totally agree, NOS with 1.4 is fantastic!I agree, I'm loving NOS with 1.4 and so far so good. I won't go crazy with this firmware thing, as soon as I want to get a warmer presentation I'll take 2 minutes max
Loving my Pontus since I got it and never looked for any other DAC and it's over 2 years already

I have just updated the Terminator II DAC to the v3.7 firmware using Hermes DDC I2S connections.
The procedure was quite involved but with the insightful & quick help of Vinshine on a couple of stages (resetting of the clock sync & out) it was completed successfully.
Thanks to Vinshine's support and great products!

I had to adjust both clock sync and I2S pinout.

After 48 hours burn-in of v3.7 on my T2 + Gaia I'm very happy with the new firmware. The sound is more transparent, present and detailed. Probably a little less warm. It is like getting more revealing cables. FWIW I was using NOS before the update and continue to use it now.
Upgraded my T2 firmware with Windows 11 tonight. Bit of a fiddle to disable Windows Driver Enforcement on Windows 11. Several methods I tried from the Run window and F8 on boot-up didn’t work but this one did.
https://pureinfotech.com/disable-dr....,Disable driver signature enforcement option.
I also had Windows SmartScreen and Defender issues but shut those down so the Flash file would run.
My favourite test track, Alicia Keys - Rock Wit U from her album Songs in A Minor in 24 Bit 96.0 kHz has never sounded more transparent and peppered with percussion detail on my Susvaras. The T2’s slightly over-polite treble has been gently sharpened a tiny bit closer to perfection.
Great job Denafrips and Vinshine. A new high water mark on an already excellent product.

Yes, as stated by CAJames I had to 'adjust both clock sync and I2S pinout.'I had to adjust both clock sync and I2S pinout.

I think that's whats cause the biggest problems for DDC users... People think they "bricked" it when it's just you need to reconfigure both clock and i2s to have it working again. Alvin should state it clearly on the info like in bold or something

Agreed. They should also mention some old version Iris DDC is not compatible with the new DAC fw update (at least not for T2/+ V3.7, can't play both PCM and DSD files correctly). Wait for a new fw update for the DDC...I think that's whats cause the biggest problems for DDC users...
