For Leyla, nothing to say on the qualitative aspect of the music but if the audio blu-ray is supposed to best reflect the original master, recording Leyla is simply bad.
No dynamic due to excessive compression, Leyla is one of the worst editions qualitatively. Obviously, Universal is not or could not leave the Downmix (the latter may be unavailable or sabotaged because of drugs taken during the recording sessions, see the history of the album). Wonder is the opposite quality level. This is an example of Loudness War before the time when the sound studio. So we will say that the style is wanted.
This version can therefore fill Clapton fans will bring nothing but an audiophile point of view. It's big sound very heavy FM, nothing more. Barbara editions, Brel, Supertramp are seen above a qualitative point.
