Walk-in soundstage

Coupled with his Weiss DAC 204 and T+A DAC 200, Mr. Steve Huff claimed to have experienced the so-called "walk-in soundstage" when using the Lumin U2 as the streaming transporter. This refers to a deeply immersive, three-dimensional stereo image where the listener perceives the musical space as so realistic and spacious that it feels as if one could physically walk into the soundstage.

This level of presentation is notably different from the more common “layered” sound field that many average listeners or reviewers report—where the sound is merely projected in front of the listener with some layering or spatial envelopment.

I'm curious how many of you have also experienced this effect in your own systems and listening spaces. If you're open to sharing, I'd love to hear about the components and setup that helped you achieve it.
