| Tonearm mount to the plinth vs arm board vs rotating arm board vs isolated tower Atmasphere"Or you could use a mirror mounted on the item under test, a laser and a sound source to demonstrate how a separate arm pod will not vibrate the same as the plinth onto which the platter is mounted, even if both use the same construction... | |
| Tonearm mount to the plinth vs arm board vs rotating arm board vs isolated tower CoolHow much weight can the Herzan carry?Cost?Self noise generated by the action of playing a record.What do we do with this energy?Sink it, dissipate it in the TT structure, both. Cheers | |
| Tonearm mount to the plinth vs arm board vs rotating arm board vs isolated tower Halcro.Quite a number of people have reported on the efficacy of the Herzan stands and their equivalents.Out of curiosity what do the three graphs, V, H1 & H2 represent? Velocity and frequency?How does the stand reduce self noise in the TT str... | |
| Tonearm mount to the plinth vs arm board vs rotating arm board vs isolated tower Yes, while Mark and I have taken significantly different paths in our designs, we both agree on the fundamentals. We just approached them from different perspectives. | |
| Tonearm mount to the plinth vs arm board vs rotating arm board vs isolated tower I echo Lewm's comments re the Helix TTs.Mark Doehmann's design is innovative and unique. Way cool. I have heard them a number of times and they are exceptional. I have also met Mark twice. He is totally open to sharing his extensive knowledge abou... | |
| Tonearm mount to the plinth vs arm board vs rotating arm board vs isolated tower Amateur? Hmm. I would point you to this post..... OMA (Oswalds Mill Audio) Debuts K3 Direct Drive Turntable—An AnalogPlanet Exclusive Michael Fremer | Feb 28, 2020 | |
| Tonearm mount to the plinth vs arm board vs rotating arm board vs isolated tower There is an interesting conundrum at play here.I quoted Einstein quite deliberately.”Does the Station stop at this Train?Looking at this another way, if the Station and Train are rigidly coupled together AND moving. A passenger in the train lookin... | |
| Tonearm mount to the plinth vs arm board vs rotating arm board vs isolated tower I think that it was Einstein that said “Does the Station stop at this Train”Now I know that I’m stretching the point a little but as Atmasphere said, to paraphrase..Relative movement between the arm mount and the platter is a bad thing. We can h... | |
| VPI's new "Vanquish" Ultra High-End turntable is a STUNNER! OKThanks for the explanation.Interesting drive design choices Cheers | |
| VPI's new "Vanquish" Ultra High-End turntable is a STUNNER! Phoenixengr.”.. encoder with 90 poles... “Or perhaps run with a higher interpolation multiplier?cheers | |
| VPI's new "Vanquish" Ultra High-End turntable is a STUNNER! Hi phoenixengr.i assume that they are using encoder interpolation to get the count up to 2560 P/R? Cheers | |
| Stylus-Drag..Fact or Fiction? Hi phoenixengr. VPI have made interesting choices in the controller and motor. You would think that Thingap would make a motor with low speed/power windings ( higher resistance ) making for finer speed control from the Elmo.All that said, the TT... | |
| Stylus-Drag..Fact or Fiction? Hi phoenixengr. why do you think VPI use trapezoidal commutation?Surely this is not optimum if they want to minimize torque ripple. Cheers | |
| Stylus-Drag..Fact or Fiction? Mike.Exactly. This is what I was trying to say with respect to dynamic speed stability, (steadiness)The level of granularity we use to measure TTs is simply too crude to show us what is going on in real time under dynamic conditions. But we sure ... | |
| Stylus-Drag..Fact or Fiction? chakster.I said... "I don't claim to be able to hear this difference"You seem to be agreeing with me?. |
