Good quality RCA TT switch?

Thanks Albert, but the Skipjack is priced at $1650 new! That's more than I am willing to pay for an A/B switch.

Have you considered 1 table with 2 arms? Also, many phono pre's have inputs for mm & mc. You could run one of each per table?
Personally, I'd avoid anything that might add hum to a table.

Like you, I looked at the Skipjack, saw its price, and said "you gotta be kidding me." At the risk of being pilloried by my fellow A'goners, I'd suggest trying a Dynex DX-CVS4, which will cost less than $50.00 (it can be bought at Best Buy) and has a wireless remote (Logitech remotes can be programmed to work with it, as well). I use one to add extra inputs to my Krell preamp for a tuner and CD Jukebox, and it seems to work fine. If you try it and feel it causes "sonic damage" you can return it to Best Buy. If not, you've saved $1600.00 and have a wireless remote, to boot!

Incidentally, there doesn't seem to be much between the two options. I looked for other solutions, and there doesn't seem to be much out there.

Well, after a couple hours trying to make Google my friend, I'm inclined to agree. There doesn't seem to be much in between the two options you mention Rdavwhitaker.

Amazing that there isn't a simple high quality stereo RCA A/B switch on the market ...?

Niles makes what you are looking for.
