I have 2 of their 180gram vinyls. The 45 reissue of Getz/Gilberto and the Louis and Ella.
The Getz/Gilberto is an amazing recording on vinyl! Just as good or better than the SACD version that I own.
The Louis/Ella is good, but just not as good as I had hoped for. Likely, that comment is more for the material rather than the sound quality (IMO).
Concerning a Hybrid SACD--That's exactly it, it has SACD encoding AND CD encoding on the same disk, so any CD player can read those CD encoded layers.
I have never tried to verify that they really went back to the original master tapes. But, as far as I can tell, I'm pretty sure these guys started this company as a passion project, so I have no reason to suspect their info that they provide.
