The Dollars trilogy on LD has the original English dub audio WITHOUT all the noise reduction and severe EQ that severely cut the atmospherics and detail.
They sound as good as vintage prints but clearer due to a proper transfer and not being degraded optical tracks. There is some intrinsic noise to the sources here and there, but it is beyond putting up with due to the uncut dynamic range. Even the Morricone scores play generally without distortion!
The only downside is that FAFDM is cut in little bits all over the place. The new German uncut BD is supposed to have the English dub in DTS. GBU is overmatted and uses some kind of Italian-US hybrid source. I've got the rarer reissue and will do a comparison later.
