Why do turntables sound different?


Let's consider higher-end tables that all sound excellent. Same arm/cartridge and the rest of the chain. Turntable is a seemingly simple device but apparently not quite or not at all.
What do members of the 'scientific community' think?

Interesting thread. We all know table/arm combo's will sound different. I liken it to global climate change. We all know its going on but it is difficult if not impossible to distinctly say why. There are a lot of factors. I tend to like the high mass tables with air bearings in both the platter and arm as i "think" this helps isolate or protect against sound effects from non-groove sources. How much is caused by what mechanism but every link along the chain from the source (ie groove) to the speaker impacts. Even the wire choice on a moving coil is touted as having an impact on the sound. I tend to agree with the crux of many of the responses in that vibrations caused by a variety of sources will impact the sound. I know that bearing induced sound from my old Michell occurred and changed as i tried different bearing types and oil types. Even the air bearing system will have a faint sound, though much less than any other table i have heard, as i rotate the platter as even with these there still is a centering pin that does provide some contact from platter to the table base. I do also agree in keeping the table if possible in a separate room from the speakers. is this a huge impact, not sure, but i do it primarily to keep my electronics in a more controlled environment. 
Obviously these are just my opinions and not based on scientific measurement but rather from 40 years in the hobby with many different tables
