    Do we need another high-end turntable? The Ars Machine M1

    Russ, another thank you from me. I am delighted that you are enjoying the BM1 so much.

    Three no trumps when vulnerable

    I find this approach to a cartridge very interesting. I know strain gauges very well from my work with milling machines. I have often wondered whether this principle would be suitable for cartridges. I am pleased that this idea has already been realised. Maybe I can listen to one soon?

    Tone arms that doesn´t need a mounting hole

    Right now Gary has an BM1 and a Lignum L for demonstration. We are now building two BM1s. One of them is going to the East Coast. Please contact Gary (gleeds in the forum) for more details. Feel free to contact me for technical questions.

    Considerations in turntable development

    Sorry that my answer comes so late. Attached you will find a file showing the most important innovations on the M1 turntable. The text in the attachment is in German. Please pay attention to the drawing. Here is the translation of the text for you: Platter: The parts of the turntable are...

    Auditioning a turntable is kind of ... impossible?

    Yes, exactly. The table of the TM1 fits only the M1. With the BM1 it is exactly the same

    Considerations in turntable development

    In another thread we came to the question of what considerations and experiments are made in the development of a turntable. Specifically, it was about the design of platters. In order not to deviate from the topic there, I was asked to open a new thread. Therefore, I would like to describe my...

    Auditioning a turntable is kind of ... impossible?

    If that's okay in WBF, I'll be happy to open a thread explaining my findings on platters. Whereby these things apply in principle also to the other parts of a TT.

    Auditioning a turntable is kind of ... impossible?

    No problem for me. I have the impression that the others are also interested when I explain my theory further. If you are aware of the effects of the parameters mass, stiffness and damping, you can look at a platter and judge its vibration characteristics. The most common design in high-end...

    Auditioning a turntable is kind of ... impossible?

    It was not my intention to draw attention to the Ars Machinae turntable through my post. In German forums such a thing is not allowed at all. A direct comparison with another manufacturer would also be problematic. If it is allowed and desired here, I would of course like to answer the questions...

    Auditioning a turntable is kind of ... impossible?

    May I bring in a completely different point of view here. I am referring to the original question. A record player is a technical product whose properties are usually clearly visible from the outside. Its sound quality is directly related to the vibration behavior of its components. Therefore...

    VIV Laboratory Rigid Float Tonearm, first experience.

    I am sorry to tell you that you have misunderstood something here. Overhang, offset angle, P2S, effective length and the position of the two points where the tracking error angle is zero are the parameters of the tonearm geometry. These are all directly related. I spent many hours studying these...

    VIV Laboratory Rigid Float Tonearm, first experience.

    From the geometry, there is a clear relationship between the offset angle and the skating force. If the offset angle is zero, the skating force is also zero.
