One turntable with two arms, or two turntables with one each - which would you prefer?

@noromance  Brian, you are very kind. Hopefully you are enjoying the warm glow of tubes in great health. Perhaps i shall return in some depth…after close of fishing….. perhaps….

Push the button, drop in a CD, hit play…voilà! No tonearm or phono amp required. 🤣🤣🤣

I've seen Steve at VAS change his beloved Uni-Pivot arms on his VPI. It seems easy, until ....

change arm: pull out mini-din connector from the VPI junction box: that mini-din connector now dangling from delicate tonearm wires. Simply lift arm up, put down in safe location. 

Pick up spare arm from safe location, with alternate cartridge pre-mounted, pre-aligned. Place on the arm base spike, plug in it's mini-din connector.

NOW, cartridge body height might be different, reset VTA as you mentioned. Cartridge weight likely different, it's recommended tracking force probably different, and thus anti-skate should be re-adjusted.

VPI arms used to skip anti-skate, they said "put a twist in the wire" from tonearm to junction box (oh that's precise), then they started making aftermarket anti-skate devices, VPI now offers them

I have changed arms on my friend's Technics B500 base, no delicate wires involved.

Changing a headshell with pre-aligned cartridge, then the same VTA/Tracking Force/Anti-Skate is needed. 

Second or 3rd arms, very carefully aligned, ready to go is much preferred if alternate cartridges are used.

A true Mono cartridge DOES make a difference, slight or a lot, varies

Same here. I’ve one turntable with 12” and 9” arms going to a solid state phonostage, and another turntable with a 12” arm going to a tube phonostage. Very nice to choose based on the music!

One tt with two arms is perhaps more economical. One platter, one motor, one motor controller, one footprint, etc. And this scenario also allows for a mono and stereo cartridge, both with precise positioning/tuning. (Single arms with multiple headshells and bayonet mounting, or multiple unipivot wands do not offer this.) Not to mention compliance matching limitations between cartridge and tonearm choices. My Brinkmann Balance achieves this nicely. But I also have an AVID Acutus SP that I just can’t seem to part with. I love the ease of set up, that it will hold its set up, virtually forever, and it’s still punches way above its class imho. And just love the way it looks, a beautiful industrial design. So this second turntable and third tonearm offers the opportunity for experimenting with other cartridge ideas while maintaining a rock solid mono and stereo set up with no fuss. All of this runs through a Aesthetix Rhea Signature phonostage that accommodates the three separate inputs. Again, one piece allowing multiple functionality. It’s nice to have choices. But to each their own. It’s all good.
