I just bought an M4000D mini. I also have one of Markus' Mk. VI's.
I did an A-B comparison recently and there is a difference. The MK. VI has a bit more "presence" if that makes any sense. The difference isn't vast but it's there.
Having said that, the M4000D still sounds really great. It operates well and certainly feels nice when I'm playing it.
I simply have neither the money nor the storage space to continue buying all the tapes I'd ideally like for the MK. VI. Also, I use the tron a lot for recording and having to continuously swap tape frames on a piece with multiple tron sounds is a bit of a pain on occasion. I also can now gig with good sounding "tron" - hauling the MK VI around simply wasn't viable.
So for all those reasons, I'm very happy with the M4000D.
Let me know if you have specific questions.
