Given that the needle is following the track, there will be some amount of friction, which means wear. No exceptions. While a good turntable will minimize that wear, it won't eliminate it. The only turntable that didn't have wear was one that used a laser to follow the tracks.
Rubbish. You know nothing about turntables and vinyl replay. Please explain how a needle can follow a track without any friction whatsoever.
Indeed. Michael seems to have found a way around the basics of physics.
Friction means wear.
My knowledge of the laws of physics is about nil.
Wheras some of here are not only very knowledgeable in that area but also electronic hobbyists who grew up to work in the profession.
I didn't say there was no friction between a stylus and a record groove. What I'm thinking about is how detrimental that is to the record and how long it might be before it becomes audible. I do not accept that it's a big problem for vinyl replay. I've played lots of records for many years and never worn any of them audibly. Microscopes would no doubt show the degradation between plays of any given record, but so what ?
Trying to reproduce music by means of audio equipment is pretty much looking for some sort of Holy Grail and by definition unachievable. So you use the tools available, in my case I get the best results from vinyl. I am not anti digital per se I just don't find it as musically satisfying as vinyl.
My prejudice is for a pair of 1970 era 104-A/B speakers. That 'last mile' was always the weakest link in the audio chain. Japanese speakers always seemed 'brassy' to me. Amplifier? Quad published details of their 405 feed-forward power dumping amp in Wireless World while I was studying for my EE and a group of us debugged and 'improved' (the published circuit had deliberate errors) and produced such amps for our own use and that of friends. There must have been about 50-60 of them around the campus; we just gave away the PCBs and a parts list. I managed to blow up a couple :-) One of us built some BIG speakers, about 5' high, filled with sand. Each speaker needed a pair of the 405's back to back in push-pull mode. Six of those blazed out at the Queen's Silver Jubilee. -- /"\ \ / ASCII Ribbon Campaign X Against HTML Mail / \ -- The bitterness of poor quality lingers long after the sweetness of meeting schedules is forgotten. --Kathleen Byle, Sandia National Laboratories -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
