  • New Plinth with 1 or 2 tonearms?

    If you were to build a new plinth for your turntable, how many tonearms will it support?

    I have a plinth with two tonearms but it is so big... it is difficult to find a rack with big enough top shelf.

    On the other hand, as a fickle audio gearhead, if I were to get a plinth build... someday I might need to sell it to get something different. Then having a plinth that supports two tonearms might be more interesting to the next person.

    two...one for my stereo cart of choice and one for a mono cart/arm, if you have a mono record collection.

      It always seemed to me like an accident waiting to happen.

        There are plenty of racks with a large top shelf to fit the VPI TNT size. I'd definitely want 2 tone arms, one stereo, the other mono. Most phono amps come with 2-3 inputs anyway!

          I'm in a special situation. I WANT a table that can handle three arms. Those three arm positions must be identical in mounting however and that's where some tables fall short. Ken's table can handle three arms easily. I think the AF accommodates two and the mounting is identical.

          But then you want a phonostage with three inputs right?

          Two arms so I can set up two cartridges essentially side by side for review, adjust the SRA and not have to remember where I set it when switching arm wands. Then a third position for any arm that might come in for review.

          I understand the mono thing but my records start with the stereo era.

          It might be interesting to have a separate thread listing the tables that can really handle (not some klugey setup) more than one arm.

            Myles why would the arm mounting positions be different on a table that was designed to accommodate two arms? I have seen tables with adjustable mounting points that I am assuming is to adjust for arm lengths?

              One example is the VPI TNT, HRX or Classic series. Yes they can take two arms but the "back" mounting is not the same as the side arm mount.

                Myles please clarify the mounting point not being the same. Thanks

                  Some tables don't have identical geometry for two arms. For example, on one mount you maybe able to install a 12" arm and on the other mount only a 9" arm.
                  Micro Seiki SX-8000 table with flywheel, SME 3012R arm, SME 312S arm, Lyra Etna SL and Dynavector XV-1S cartridges, ARC Ref 3 phono stage, Otari MX-55 tape deck, Ampex 350 repros, Roon Nucleus Plus server, PS Audio DSJ DAC, ARC Ref 6 pre, ARC Ref 75 amp, JBL 4345 speakers, and Def Tech Ref subs.

                    Thanks Mark for the explanation. Myles I didn't know you could install two arms on a VPI classic series table? I have heard VPI is working on a second arm mounting for the Prime.

                      That is exactly what I saw on the early VPI Classic tables. One 12-inch and one 10-inch arm. That's why in part the back mounting isn't optimal even on the TNT. The Avenger is another story. It's built from the start to accommodate three arms.

                        Two max for me. When I had 4 at one time as Johnny says, it felt like an accident waiting to happen. Left and front right positions were very awkward for me. A different story if my table was on a rack I could walk around but that was not the case.

                          What table did you have four arms on?

                            My AC-3 Myles. I had a TW, two B-44s and a TriPlanar on it.

                            I like the TW a lot. I put it up for sale but withdrew a few days after. I decided to keep it for a second system for a vacation house I'm planning. Does the AF1 do things it can't? Sure BUT that doesn't take away from the fact that the TW is every bit todays as the day I bought it. A very capable table that is for me first and foremost musically engaging especially with classical music.

                              My table will take 4 arms after this many years and I count up the number of arms it comes to ONE. Just lazy I guess so one Tri Planar thats it. And a SME V in the back room on a SOTA
