After all these years of owning the BluRay, tonight I finally watched it (new 55" screen, I picked the restored English mono track this time). I thought the image quality was great, but not perfect. Totally fine though. The audio had some kind of beeping in a few moments, not sure where that came from. I will try the DTS Surround track some other time to compare. It is definitely a huge step up from the old DVD. When the menu comes up I pick the restored version over the theatrical version, even though it’s still not the definitive cut, I know. To me however still - after rewatching it I feel even more so - the most perfect of all spaghetti westerns.
