If anyone can explain why one might intentionally have two turntables, I'm curious.

I currently have two turntables in my main system. One costs about ten times as much as the other. I use the "nice" turntable and cartridge with my better records. I have some records that are less pristine that I still enjoy mostly for the music and would rather not wear the stylus on the expensive cartridge with those. Others have more than one because they sound different and may prefer one over the other with certain types of music. As someone else mentioned, some like to have a separate table for mono. I'm sure there are other reasons. 

One can own 4, really.  2 operational, 1 owned for grins, and 1 in 2 parts; table and arm.

All tangential.... Go figure. *L* ;)

Hats off to anyone that has the passion, and means, to build a listening room such as this, and fill it with outrageous gear. I'm in awe. That being said, I'm glad that when folks enter my listening room we concentrate on the records and CDs, as they are worth 10 times my decent sounding equipment.

Recently saw youtube video where guy had something like seven systems throughout his mansion, expensive equipment in every one, and it appeared he kept all powered up 24/7, the electric bill alone!

I don't begrudge anyone for following their passion.
