| Turntable upgrade recommendations: SME vs AMG vs Technics vs other @mijostyn "with modern machining bearing tolerances can be very close to perfect" Agreed. It’s the "close to" that tells the story. In the old days, bearings were machined fairly closely, and then rotated against each other in situ, with fine g... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other You may find more bang for the buck in a quieter TT than in signal processing. Ralph (of Atmasphere fame) often suggests spending a lot on the phono stage to the same end. As a general rule, every active device (transistor or tube) in the signal ... | |
| Interesting information from Analog Planet on Stylus Cleaner Onzow Zero Dust. @rickd1225 Thank you! Expertise over speculation 100 times out of 100 ! | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other @mijostyn After reviewing my earlier posts, I think that you were quite right to criticize them. Sorry for the aggressive tone in my response. | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other @mijostyn "Raul mentions the heavier the platter the higher the resonance frequency and there is no practical way to dampen an air thrust bearing. All you can do is adjust the frequency it resonates at" Not so. A properly designed platter does ... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other @rauliruegas "Any body in movement develops internal vibrations/resonances " Almost true. But those resonances must be excited by vibration. Where does that energy come from? Not the air bearing - you are thinking of a conventional bearing, per... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other @alexberger I had a similar experience with a NA Spacedeck compared to an upscale NA, the Mentor. Happened gain when upgraded the Mentor to full NA Dais specifications. Happened again with the modern power supply. Happened again with air bear... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other @mijostyn True, a resonance can develop. But this is easily controlled with a massive platter, a well damped air supply, and tuned air pressure. There is no reason to think that magnetic suspension is quieter, but there is good reason to be susp... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other MODS - attention please. When trying to post, I am sometimes asked to prove that I'm not a robot. But the last inch of screen is obscured, and the page will not scroll. Could you pass this bug along to the systems people, please? | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other @rauliruegas "SME has nothing to envy against those air bearing TT designs." Not even a completely silent bearing? | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other @mijostyn Thanks for your input on air bearings. I agree that air in all directions is important - how not when I can hear the sleeve bearings of my 2W precision motor? Even through a belt! Didn't know that air in all directions was so rare. T... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other To complete my thoughts, bearing noise in a turntable is not always recognizable. In a quality turntable, it can manifest as high frequency distortion on top of the signal, which appears to be clarity in the triangle or the harpsichord. But this i... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other Air bearing tables are many and various - but all of them are expensive. Mine is a DIY with air in all three dimensions. I did this with porous graphite bearing surfaces from the US company New Way, using the larger of their so-called thrust bush... | |
| Bully pulpits Kruger-Dunning on tiresome display. | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other OMG, I agree with MC. Anyone know a good shrink? |
