Why Would a Turntable Need More than 1 Arm ?

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 ... :-)

Yeah, Syntax is right. I have Rhea for my 2 arms TT. Then I have it upgraded to Signature. I was able to borrow Tron but with only one input. Somehow I don't feel complete. When you're already there, it's hard to go back again.

You may have only one arm, for instance with an EMT table, an EMT 997 or Ortofon RMG 309 you can switch easily from Stereo to Mono carts without alignments at all. If you are going to be happy with one tonearm in this constellation you have my respect.

However as stated above there are so many more options if you decide to go for more tonearms and many different carts. It is on the other hand the entry into the ongoing discussion what makes sense? Believe me it makes sense if you start becoming addicted...
