Gimbal vs unipivot tonearms

@rauliruegas:     "You are rigth but the unipívot behavior is way similar in between this kind of design."

         I would never deny that fact, BUT: nor would I ever categorically state that the design could not function very well, if not excellently, if properly incorporated with an appropriate cart, base/suspension, etc.

          You mention having tried to purchase the Unitrac I, on eBay.    Obviously, then: you're familiar with what they can bring, even if just for parts.   Especially: in Japan

           Some out there appear to share my opinions, regarding the arm.

            "...you are happy and this is what it counts: rigth?"

            Whether when I had my business, the contract work afterward, or running sound for a band; the customer/musicians always got the sound signature that pleased THEM, whether I thought it sucked, or not.

            My philosophy, there: "The customer always thinks they're right!"

             Happily: the vast majority were open to learning and, subsequently, very pleased.

I have a 3D on my Classic 3 Sig SE.
I’m one that tries to turn lemons into lemonade. After I had VPI get the S2P distance right and the addition of the dual pivot upgrade, I’m happy with it. In addition, what made the dual pivot much quieter, is my PEEK film upgrade.  Next is having it rewired with a continuous run of Audio Note silver.

With all due respect and appreciation for the knowledge and experience shared here, the inclusion of an Audiomachina V8 Broad-Spectrum Cartridge/Tonearm Vibration Absorber between the cartridge and tonearm will likely far surpass any difference between a well set up gimbal or unipivot tonearm.

I have the Origin Live cartridge enabler in house.

no worries with a warped VPI....they send a new one.
