A lot of haters making comments on their website. From my knowledge of working in the audio biz, mixing down from the original multi-track to a 1/4" half track tape results in a master.
So they are selling masters, but what is not mentioned is that the original multi-track is digital and is most likely coming from a DAW and not tape. IOW, they are mixing down a digital file. Vigo finally does mention this in the comments section.
So, I'm sure the master you buy is very high SQ, but their sales pitch is misleading if you are expecting the sonics of an analogue reel to reel recording. Whereas, The Tape Project sells a copy (a dupe or dub), transferred from their 1" master tape. Their recordings are entirely analogue and will have that distinctive reel to reel sonic signature.
