P2 or P3
The motor upgrade has been said to be noticable but not that great a leap as an upgrade,I think it has more to do with pitch stability problems with the Planar 2 and 3 generally,which can be cured by a couple of lengths of electrical tape around t...

Sorry, I meant to say the RB250 has a brass stem and a plastic stub,whereas the RB300 has a steel stem and steel stub in their stock form.You get rid of the plastic stub on the RB250,replacing it with the metal counterweight of your choice,there a... 
P2 or P3
There are reasons that a modded RB250 can better a modded RB300.Firstly the RB250 still has bearings on both sides unlike the RB300 where they have removed 1 bearing to put a seemingly improved Bias adjuster in.The RB250 stem is brass as opposed t... 
Frequency Response of L.P's
The frequencies in the ultrasonic area of LP's do not seem to "wear out" after repeated plays.The article by Stereophile's editor-in-chief John Atkinson called "What's going on up there" found in their archives section on-line is absolutely essent... 
Frequency Response of L.P's
Yes,Mr.Neve says that he does not really know what makes us perceive sounds the way we do,but is a firm believer in wide bandwidth for commercial recordings.Anyway what goes on an LP in terms of bandwidth which was my original question and we seem... 
Frequency Response of L.P's
The story about Geoff Emerick is true I have seen 2 Rupert Neve interviews online where he repeats it,and a discussion on a Pro-Audio forum talking about it and how well thought of he is.Anyway in a transcript I have,Mr.Neve talks about his 5106 C... 
Frequency Response of L.P's
There is the old story of Geoff Emerick the Beatles guy calling Rupert Neve in to suss a fault on a console,that he designed,and Emerick's "golden ears" were not happy with.It turned out that Emerick could hear a fault in 3 panels generated by a 3...

When I had a look for this cartridge Audiocubes online had the best price.stefanl 
What to do with Acrylic Platter?
I think my mistake was not taking the original platter in for proper measurement.The machine shop said later they could not guarantee exact size,I got 2 platters and have settled for using a rubber O ring from a hardware store which gives a tight ... 
Goldring 1042 or Rega Exact
That must be correct reference,sorry.It was off the top of my head from a thread I read on acrylic platters over at Vinyl Asylum, someone said that he had discussed the subject with Mr.Conti,who seemed to like the material.stefanl 
Goldring 1042 or Rega Exact
I do use a form of mains power filtering I must admit, and have sat for some time with a stopwatch counting revolutions.My table deviates maybe, by about 3/10ths of a second per minute,perhaps with stylus drag it is right on spec.as the strobe loo... 
Goldring 1042 or Rega Exact
Psychicanimal,you are correct when you say the weak link is the turntable,but there are ways around this.Firstly check the speed with a downloadable strobe from Extreme Phono's site.Planar 3's are usually 1-2% fast.To correct this, 2 equal spliced... 
OK, I said it...
The resonant frequency of your Ortofon Kontrapunkt B is about 9.8hz with the 11g Rega arm.This is too low.You must accept 10hz as a basic minimum on a table of this quality because you are going to hear it.This has been discussed in the thread on ... 
Damping Rega Table
Having considered my immediate options I put together a slap-up job of a 2inch concrete slab on pointy rubber feet as an isolation platform.Should I later try sorbothane feet on this? It is quite heavy and might be too much weight.stefanl 
Need help with Ortofon stylus force gauge
Yes,you seem to have grasped the gist of it.I have an Ortofon gauge and I use it to approximate the weight.It only has 1.5-2.0g given on the scale.So you set it close to 2.0g i.e where you think 1.8g should be.Then you iterate around this area unt...
