Does anyone run 2 or more turntables...

I have one optimized for superior fidelity and the other rigged for records that are not in the best condition.

I run two turntables and a microphone, that's where it's at my friend. ;^)

Soon to have a second TT so I can have one for MM and one for MC. I also have two CDPs cuz "sometimes you feel like a nut...sometimes you don't". Happy hunting!

I have one turntable with two arms so I can access different cartridges. Many times I’ve had two turntables in the system, typically short term to test one against the other to determine best performance.

I would like to have two “best” turntables with different high end tonearm and cartridge combinations.

I've got 4. Three are always set up for listening, two in my "upstairs" system, and one in my "downstairs" systemm. Yes, two complete high quality systems always at the ready. If you count my Victor TT101, which may never be reliable enough to listen with, I actually have 5 turntables in fact.
