While my background is in engineering, I am not a metallurgist either. But I do know that 316L is considered an non-magnetic material (see https://greenwoodmagnetics.com/resource/what-is-the-difference-between-304-and-316-stainless-steel/). But even ...

The Manufacturer told me, the Model 3 has a lot of identical parts from Model 1 (Motor-management, Materials, Vacuum, Air bearing, Glass platter...) and they want to serve more customers, Price is 50% of Airforce Two.One of my friends owns the Airfor...

Thanks for detailed answer. I'll go for 316L. So I would not worry about magnet issue, especially because also I use CU-180 or Audio Technica AT-666EX mat (air suction type).
As my taste is closer to steel I have plan to make also the 316L version...

Thanks Romy, your comment above cleared some of the questions I had regarding 50/60hz midbass horns.I found some info on the driver after digging through Japanese sites. I don't know if these info will help interpret wither the woofer will be go...

That is a whole another subject all together. I truly have no strong opinion on the subject but I do hear a lot of talking noise about the “quality” of motors for heavy belt driver turntables. My idea is that with a sufficiently heavy platter and pro...

[quote user="Romy the Cat"]Hm, I took the anti-RIAA signal converted and run CD player into the phonostage. The RIAA curve was fine and the effect of the HF volume and frequency-depended quantization did not expose itself. So, it looks like the p...

People asked me: Romy why don’t you try to transfer some analog to digital and see what happen. I was queries myself and I decided to try tonight.
Whatever I did was in a way half-ass but I was interested in “as is” result. Although the attem...

Paul,It would be improper for me to write down what I have worked on over almost 40 years in the telcoms business. WRT a CV for example, I have in the past written it all down and the reviewers do not believe it. Eventually, i stopped bothering abo...

The Rockports have a very light platter and a carbon Arm....the one I listened to was the latest, it had simply no Bass reproduction, nada, nothing and the Arm resonances are also inferior to any energy transfer from any cartridge. The lead wires are...

[quote user="Serge"] It's silly because the minuses outweight the pluses. In order to suspend the heavy disc constant magnetic field should be strong. This field will easily travel through the platter, since the platter is by definition non-magne...
