I recently purchased all 3 of these Santana SACD's even though I have the SQ vinyl and Q8 conversion's. I feel the best mix is on the debut and this might be because it was the last one to be released. Many tracks on the earlier released Abraxas & III in my opinion suffer from being too gimmicky. And yes I do like immersive mixes but some of these are abusive like the sonic kitchen sink was thrown in just for fun. For comparison look at the highly rated Doobie Bros. mixes which are immersive but don't scream "look at me I'm quad". Unfortunately this was a problem with many early mixes and I think unfortunately Abraxas & III suffer in this regard even though they seem highly regarded in the surround poll.
