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

I went to 1 TT with 3 arms, I don’t have room for two TT’s, and 1 SUT with 3 inputs to 1 Phono Stage, and PASS for MM thru the SUT to that favorite MM Phono Stage.

I’m gonna assume two arms means you will get into MC cartridge. And 1 arm could be fixed cartridge, but the second should be removable headshell so a variety of cartridges, i.e. MONO, MM, Elliptical. Advanced Stylus could be acquired over time.

MC Low Output means a SUT to get up to MM signal strength.

SUT with PASS for MM.

SUT with two selectable inputs; out of SUT to single Phono Stage.

.......................

My Fidelity Research FRT-4 SUT has 3 selectable inputs, PASS, and 4 optional x-factors/impedances

this one is over-priced, but shows it’s features, they often show up for around $700.

Entre ET-100 has 3 inputs, PASS, and 3 optional x-factors/impedances, usually cost a bit less that the FRT-4.

Note: FRT-4 has internally connected output cable with old simple connectors

Entre ET-100, rca jacks: you can use your own output cable, better connectors, I may modify my FRT-4 one day.

This 7 layer JVC Victor CL-P2 Plinth is what I have.

Two Removable Arm-boards, normally 2 arms.

It fits JVC Spinners: TT61, 71, 81, 101 (don’t go there). I chose TT81.

Three Arms:

1. rear 9" Removable headshell, various cartridges, MM, MC, ellip, shibata, ML ...; Arm has VTA on the fly for easy cartridge height changes.

2. right side can be long (mine is 12.5"), best MC cartridge, fixed..

3. Then I found a compact Mission arm with a short counterweight section and ’squeezed’ it in, for MONO ready to go.

the mission arm is made by Jelco, there is a Jelco matching model, and you do not need the mounting plate, just mount the round base ring, 3 screws.

Luxman Two Arms, PD444

I just helped a friend acquire and set up one of these

He looked at this PBN GrooveMaster

I talked to Peter at PBN, he will make a second tonearm board and metal cap for it.
