Does anyone run 2 or more turntables...

I have Kuzma Stabi Reference with Reed 3P and Triplanar VII
in my main system. Both arms have fast headshells while I own many carts. For quick and easy cart change I have the Ikeda 345 with removable headshell on the SP 10/II in my second system.

That's why the Aesthetix Rhea phonostage has 3 inputs (not the least of its charms). I have two arms (one dedicated to mono) on my replinthed Lenco and use a separate Empire 298 turntable for 78s. Yes, I know, the Lenco can play 78s too (just as the Empire can play LPs) but whoever suspected record-playing fanatics of being logical?

Just added second TT, Kuzmz Stabi S w/ 12" Kuzma arm, platter upgrade and outboard power supply Dynavector XX2 Mk II  to Pass Xono phono Still have Linn LP12 ( just overhauled - 1988 vintage) w/ Lyra Kleos to Manley Steelhead . Tight bass SS ; Lot of air, midrange to die-for Tubes

Just to keep your thread alive, I now have 5 turntables up and running, although only 4 of them get even occasional use.  My Victor TT101, mentioned above, was finally fixed by a genius in NYC, JP Jones.  If you have a "broken" direct-drive turntable, JP can fix it. So, in my basement system, I use a highly modified Lenco with Dynavector DV505 and the TT101 with FR64S tonearm.  Upstairs, I use a Technics SP10 Mk3 (Reed tonearm) and Kenwood L07D with its built-on L07J tonearm.  My Denon DP80 is up there too, just sitting. I had promised myself I would sell the Denon if the TT101 ever got fixed, but I don't feel that urge any longer.  The market value of the DP80 is too low to make me feel compelled to part with it.

Does anyone run 2 or more turntables at the same time? What is your purpose?

Sure, I have two.  Besides just being fun, here are the practical reasons...
* One is manual and the other is a semi-auto.  The advantage of a semi-auto are obviously when is one is doing something else while listening.
* One is belt driven and one direct drive.
* One is modern and one is vintage.
* The above two points helps me avoid two classic debates in the world of vinyl because I don't have to take sides.
* Having two allows for two entirely different cartridges and both sound different.
* And back to my opening statement - its just more fun!
