Some phono stages afford multiple inputs (e.g. EMT, Lamm, Io with volume controls and optional second phono input).
But when an audiophile has two (or more) cartridge/tonearm source options and likes to switch regularly between (among) them what does he do if his phono stage does not have multiple inputs?
It is the old manually unplug source A and plug in source B or source C?
I think you are going to want a second phono stage for a second arm. I don’t think you will want to plug and swap behind the Io each time you want to use a different arm and cartridge. You could ask ddk to bring a Lamm LP2.1 when he sets up your AS.
I am using a Manley Skipjack. I bought it used. I believe they will be available again from Manley soon. Just bring all of the ground wires together with something so there are no grounding problems and your good to go with a press of a button or several bottons You will need an extra cable in this whole arrangement, but I find the losses minimal at best if any. I also think that most phono's with multiple inputs have you going through switches with probably even poorer quality so in my opinion it is the same thing for all the "nay sayers" out there that switches are "bad"
my friend and i was in the same situation last year. when my friend had just one input in his PS and i was with two.
he wanted to add one more and i needed the third,
we ended up buying switcher.
i bought something OEM from some Japanese web site, silver wiring, a decent pot and aluminium casing. no leds, no power requiring.
my friend bought his switcher from luxman http://www.luxman.co.jp/product/as-4iii
i think he was doing the best decision between us, mine was ok, but i was struggling with HUM issues with it.
the Luxman worked perfectly to my knowledge. though i didn't care much for his plastic buttons. but it just an OCD issue, not sound one
either him or me using our switcher now days... just FYI.
