From my own limited experience with these two speakers: The 5A is better than the P10 in terms of excellent ultra low bass, overall bass impact and integration with the other speaker's drivers. IMHO the 5A is very special in that it has no readily identifyable flaws unless you directly compare it to other excellent design super speakers (that excell in a certain sonic charactaristic). Even with direct comparisons, the Vandersteen is still one of the few speakers that does more right and so little wrong (as compared to so many super speakers). The P10 on the other hand does have a unique magical sounding midrange and treble that is on a level which is virtually unatainable from any speaker that uses cone drivers (such as in the Vandersteen) IMHO. I'd love to see a speaker with the Piega's ribbons and the Vandersteen's 5A woofer. Now that would be the best of both worlds!
This is really a hard comparison because both of these speakers are on my "short list" of very special speakers that would get someone out of the "upgrade madness" altogether!
