I have some Django tunes with realy poor sound quality, non-remastered.
I`ve heard that the HMV 6 CDs are digitally remastered

How does it sound?
Are the 20 volumes of the Integrale as well remastered?
Each volume in the same way? (I realise that is quite impossible, because at the time they recorded him with a technology that was improving, thus constanty changing) but i mean did they "roughly" treat the tracks the same way inbetween volumes?
And how is the HMV quality in comparison to the Integrale?
Thanx
