@audphile1 -
"if your favorite dac is a tubed AC, the odds of you liking the imersiv are near zero."
That is exactly my concern. Even considering the groundbreaking S/N and all the over-the-top accolades I have read from owners/reviewers of the Imersiv D-1 DAC, I am wondering whether its clean and detailed sonic signature is too different from the naturally organic and rich tonal characteristics of the Helene and other R2R DACs I have enjoyed, or even the Merason DAC1 MkII that I also currently use in my main system.
In his Twittering Machines review, Michael Lavorgna indicated that the Imersiv D-1 displays immediacy and excitement, and presents music "up close, personal and unadorned." He found it to improve on his reference totaldac d1 unity but he then compared it to two other DACs known for clarity and detail, the Grimm MU2 and Weiss Helios DAC. However, he did also write "the Imersiv DAC doesn’t give up the rich, warm, and lovely naturalness that I so enjoy with the totaldac."
Based on what I have heard and read so far, and on my previous experience owning the Mola Mola Tambaqui (another DAC known for clarity and detail), I suspect the Imersiv D-1 may not be a slam-dunk for me and so, as you say, I need to hear it for myself.
