To date that has always been my reference and, to my knowledge came from the first DBX decoded transfers of the show. All priors were not decoded and had more tape noise, as well as, unbalanced frequency response.
It will be interesting to compare the two and hear directly what the plangent processing did to improve the prior transfers.
One thing of note is that there has always been an intermittent low rumble for a few songs earlier in the first set. It was low in level but there for anyone who listened closely. It will be interesting to see how the handled that. I'm sure cutting out anything below 40hz could manage it but at what expense?
