| Source of Fremer's "1 arc second" claim? Guys I think that we need to cut MF some slack. In my conversation with him, I said something to the effect that a change in controller motor command in the region of one arc second resulted in an audible change in the sound. While you could arg... | |
| Source of Fremer's "1 arc second" claim? @oberoniaomnia Yes, it is an interesting trade off. We did not need to go to the max averaging available, so I'm happy with the hardware design choices I made. . The change from no averaging to averaging of 2 counts was astonishing, we all heard... | |
| Source of Fremer's "1 arc second" claim? @pryso I designed the OMA K3 and K5 turntables. Jonathan then used an industrial designer for the aesthetics. My company provides the machined rotating parts and the K5 chassis. The cast iron chassis is made in the States. Both TTs are assembl... | |
| Source of Fremer's "1 arc second" claim? Gentlepeople Michael's arc second comment probably came from a conversation I had with him about the speed sensing architecture in the OMA K3 turntable. The design sends a little over 1.3 million pulses, counts, to the motor controller every revo... | |
| Straight tonearms without offset angle I have zero experience with underhung arms but, have followed this and companion threads with interest. Some of you may have seen the talk given by Jonathan Carr to a group or audiophiles in which, amongst other topics, he talks about underhung ar... | |
| Discuss The Viv Lab Rigid Arm As Lew points out, AS is set by the user at a constant magnitude. Those who successfully opened the Youtube link I posted (the second one) will, I suspect, be surprised at the significant variability of stylus drag, and at times, its "violence".... | |
| Discuss The Viv Lab Rigid Arm Ok obviously that link didnt work...you may need to copy and past on the youtube search box lets try this Скатывающая сила как измерить (youtube.com) | |
| Discuss The Viv Lab Rigid Arm Ok I have a theory... On a conventional arm with offset headshell..if you draw an imaginary line extending the cantilever, past its suspension point, all the way backwards to the plane of the arms pivot point. Viewed from the front of the cartrid... | |
| If I could afford, I’d purchase 100% Oswald Mills Audio gear @dover. You keep track of my qualifications and my alleged transgressions on A'Gon. Really? For the record. I hold a New Zealand Certificate in Engineering (electrical). Back then it was a 5-year part time or 3-year full time qualification from ... | |
| What is the “World’s Best Cartridge”? Dover The point I was making is that, contrary to what you said, properly set up SUTs do not exhibit problematic phase errors. Nothing more, nothing less cheers | |
| What is the “World’s Best Cartridge”? Here is an interesting article on SUT's. As can be seen from the plots, they are sensitive to loading on their primary and secondary windings, including capacitance. Get it wrong and their frequency response and phase curves aren't pretty. But get... | |
| What is the “World’s Best Cartridge”? Obviously this is an impossible question to answer in absolute terms. None of us have heard all the possible contenders. But...In your opinion, what is the best cartridge you have heard?' That can be answered. I have recently started using a S... | |
| Direct Drive As I said. "The new Technics" this includes the SL-1200GR. slotless, coreless, 3 phase. Some versions available right here in NZ for $3000. The reference class Technics SL-1000R is available here in NZ for $31,999 ( Under US$20,000 ) The Pione... | |
| Direct Drive A heavy platter like that used on the Final Audio, will lower the rates of deceleration, acceleration. High inertia reduces the magnitude of speed changes, it does not eliminate them. The connotations of the words "immediately and "suddenly" are... | |
| Direct Drive I just knew I should not have hit that bee hive with a stick😊 Correct, it is not cogging, as Lew and I have already explained. “ the problem is pulsing” let’s get this out of the way..,, An 8 pole motor would be 2 phase. This is not a linear tor... |
