You are extrapolating too much from your experience with a few systems with also very few recordings. IMHO you are mostly judging
system matching, and extremely focusing on some micro details in detriment of others. The level of differences you refer involve a lot of training - you are becoming the Sean Olive of the 60's orchestras - we must congratulate you on this, but IMHO your comments are becoming too personnel to be of general use to valuate speakers to most audiophiles.
Telling that every recording played in the Alexandria X2S2 has the same stage, depth, etc. only tells us that the person who set the system did a very poor job. I have owned it for some time, but fortunately it is a speaker that is well known in the audiophile community, who has experience on it. It is usually considered an example of how large speakers can be chameleon like, having a 3D soundstage with a size that adapts to what is encoded in the recording.
IMHO if we want to compare speaker type we must focus on the best we have listened with each type, not look for the poor experience with one of them to highlight our favored.
BTW, can I ask why Rockport and Ghia, deservedly very praised speakers in the forum, never get your attention? Are they exceptions to the compression rule or are they just
"etc" ?
