I'm curious about what MFSL does to digital files for their CD reissues. Does anybody know?

Some of it sounds like there is less grunge, but for rock less grunge isn't always the best idea...


* not the LP's but the CD's

For replay of the tapes they used special RTR machines modded by Tim de Paravicini. Also claimed to be using the original master tapes but that isn't as easy to determine as it seems sometimes. Way back when prior to SACD they monitored results using Ultra Analog based 20 bit DACs which I think were VTL tube units. I think most of the gear was from TdP.

Something I've never seen referenced prior to their SACD issues were which ADC they used.

They also used those Gold discs. I always thought that a marketing thing. You hold them up to the light and the gold is so thin it is mostly transparent. On top of which all I've ever seen had lots and lots of holes where the plating wasn't uniform. As in dozens of such holes.

I have much preferred their discs to the originals. I don't know who was doing the remastering for them, and I doubt it was as simple as get good gear and play the master tape direct and record it though maybe it was. That was the story they put out anyway.

I'd analyzed a few where I had both the original CD release and the Gold MFSL at one time. Should do that over since we have pkane's Deltawave to work with. What I found were gentle differences in frequency response, and more uniform speeds on playback of the MFSL tape machine. Some regular releases had rather widely varying tape speed and sometimes had some low level tones that were artifacts of the tape machine or something else in the chain.
