It’s Stereo!
Don’t let the IMERSIV moniker fool you; we’re not talking Dolby Atmos. We’re talking about an incredible 168 dB of headroom.
The IMERSIV D-1 is a full 28-bit stereo DAC in a class of its own, thanks to Millennia’s HDR-A Multi-path technology. HDR-A stands for High Dynamic Range Audio, and the results are astonishing.
Retailing at $16,799, the IMERSIV D-1 is positioned as a critical-listening mastering DAC suitable for the world’s top mastering studios.
In A Nutshell
John La Grou and the team at Millennia go into extensive detail on the IMERSIV website and in AES papers, complete with measurements and graphics explaining how the technology works. We’ve included reference links at the bottom of this article, but here’s the short version:
The D-1 HDR-A intelligently combines multiple stacked signal paths into a single audio output, dramatically improving dynamic range and lowering distortion at every listening level. The diagram on the right outlines the D-1’s Multi-path processing architecture.
“The first thing you notice isn’t hype or coloration, it’s depth, space, and an almost unsettling sense of realism. The mix seems to almost be breathing.” - LM Pro Producer X
Just Stop and Listen
Here at LM Pro, we’ve connected the IMERSIV D-1 directly to our ATC SCM150 monitors using our DLX Series cables with Amphenol XLR connectors to ensure the least possible signal degradation.
And thanks to our resident recording statesman, Jim Zolis, we now have a fantastic collection of high-definition audio files ready to demo the unit properly.
We’ll have the D-1 set up in the shop for the next couple of weeks, May 10-24, 2026. If you’d like to book dedicated listening time - or simply make sure the DAC is still here (because yes, it’s for sale!) - give us a shout at 416-928-6434.
Feel free to bring your own high-resolution audio files as well. We also have Apple Music connected and configured for maximum-resolution playback.
As always happy recording!
