| Tracking error distortion audibility Dear Jloveys, agreed. Bob Graham is one of the - very few... - who has done literally all his homework. His tonearms are - in the very sense of the word - "complete". With his clever pre-set-up alignment he provides a tool which will enable even t... | |
| Tracking error distortion audibility Dear Axelwahl, BTW - I know Dirk Sommer - and honestly, he is NOT into tonearm geometry at all (noone of the staff at Image-HiFi is really into tonearm geometry - they are all happy if they do NOT have to mess around with that ...). The tonearm/ca... | |
| Tracking error distortion audibility Dear Axelwahl, dear Feathed, you should check and read (for inspiration...) the thread about "oldskool tonearms...." from last month. During this thread the problem of tonearm geometry was discussed in length. Inner groove distortion is either a p... | |
| Tables That Feature Bearing Friction Dear Frank_sm, if you look real close, you will find that almost ALL bearings in turntables ( not just the old Well Tempered Turntable ...) AND gimbal bearing tonearms as well as ALL pivot tonearms do indeed consist of two surfaces contacting each... | |
| Tables That Feature Bearing Friction Dear Ebm, it depends - bearing friction doesn't necessarily means increased noise. In some of the smarter designs bearing friction is introduced by oil bath, eddy current and the like to increase speed stability and damping of platter. But some of... | |
| Tables That Feature Bearing Friction Dear T_bone, I totally agree with Syntax and you. For the love of music - we do not need high end gear at all to appreciate music. Beethoven string quartet op 132 will have its impact via an MP3 player or the car stereo as well as via a million do... | |
| Tables That Feature Bearing Friction Out-of-center record hole. An important point. Still on holiday, but just a short note:I solved that problem in my earlier design in 1992. Not with a complex motorized approach as Nakamichi did, but with a total mechanic approach - very simple and... | |
| Tables That Feature Bearing Friction Dear Rhljazz, a fascinating idea. This is something really worth discussing. You happen to have any links to technical exploration and the required periphery? | |
| Tables That Feature Bearing Friction I do have a file - 3" thick and 8 lbs heavy - of extensive test and data sheets to about 5 dozens different materials which at one moment or another were part of the turntable design pre-thoughts (some finally made it). However I remember that one... | |
| Tables That Feature Bearing Friction Indeed Berlinta, you did not get a direct response. You did not ask for it either. I layed out all the points the days before. I could again answer to all the points in your last 4 posts. But I do not see any attractivity to repeat myself over and... | |
| Tables That Feature Bearing Friction The "air-pulse" drive (no pulse would exclude a problem) has some considerable problems while looking close to a theoretical ideal first. It not only will require considerably (really serious...) periphery, but indeed a "assist"-motor to bring the... | |
| Tables That Feature Bearing Friction Please take into consideration in all discussion about what drive and platter weight that is is not alone about constant speed.There is the "2nd system" (mentioned before ) and its energy transfer into the platter: - the act of extracting informat... | |
| Tables That Feature Bearing Friction Dear Dgarretson, before I get off for holiday, - first of all: very nice set-up you have done with your modificated TNT. There is much more insight and mechanic knowledge displayed in your set-up, than in many comments posted on that topic here in... | |
| Tables That Feature Bearing Friction Dear Raul, if this were a contest (a contest about what ? Knowledge ?) - it would be fairly boring.Aside from this there is nothing in your last post which requires any response as there are again (as so often..) no facts and nothing which has to ... | |
| Tables That Feature Bearing Friction Dear Raul, well we get from you what we got before - loads of technical facts, loads of IMHOs.....Yes, I can tell you what building materials in what part of the TT are most likely the best to contribute to an excellent behaviour regarding vibrati... |
