Why Would a Turntable Need More than 1 Arm ?

Many of my customers have more than 1 cartridge.

A single table with dual arms saves space and offers a degree of flexibility not found in a single arm configuration for the hobbyist who wants to experiment with different tonearm/cartridge combinations.

Dealer disclaimer.

or why a phono stage has more than one input or why a preamp needs so many inputs? "Elementary" Watson said.

Birdliver: a mono cartridge will give better results than summing the 2 channels of a stereo one but the switch is worth using if you have one. The mono is doing the job it was intended to do while the stereo cartridge will have movement in a plane that does not exist on mono records, it will work but not as well. Also added complexity is always best avoided, i.e. single channel to stereo signal back to mono.

I agree with Audiofeil and Mesael but my primary reason is
the circumstance that I prefer some kind of music with one
cart and the other kind with the second cart. BTW it is relativly easy to add a second arm to nearly any TT.

Regards,

- One for Stereo Cartridge, the other one for Mono
- one for this color, the other one for that color of cartridge
- one for Cartridge without, the other one for cartridge with body
- first one was not expensive enough, the other one is
- one 9" Arm and a 12" Arm
or the second one, because you don't trust the set up from the other one
or ... :-)
