Whilst we await a reply from Pabelson on the crux of his stance-should be very interesting.
I stumbled upon a very very detailed analysis of some of the Dylan set.
For those who don't want to read the whole thing despite what Pableson says the author here believes only 2 of the 4 Dylan albums he talks about are remixed.
These were only remixed because in those 2 instances the original finished mixes couldn't be found/used.
Since these are older albums and Blonde On Blonde has a notorious reputation (when first released it came out in all kinds of different mixes worldwide)it is logical to conclude from Sony/Columbia's mission statement(only remixed because the original mix couldn't be used) on the remastering that only 2 of the 15 Dylan albums were remixed.
Even if we throw in a few others for the sake of argument that is still daming evidence on Pableson's statement that ALL the Dylan albums were remixed.
For the record I have all 15 of the SACD hybrids.
If you go down the page of this link there is a lot of detail on the SACD releases.
