Sorry about lowering the tone of the joint with a Hi Fi thread. Has anybody close to Liverpool got a cartridge protractor I could borrow please?
I have been unhappy with the Lyra Helikon that came with my Clearaudio Ambient. I spent a lot of time setting things up again today and am a bit happier but it still doesn’t sound right. I can’t find my Dr Fieckert (last seen in Melbourne nearly 5 years ago) and the Clearaudio protractor is £185 + P&P.
I don’t really want to by one right now if I need to replace the Lyra too. If I can convince myself that the setup is correct and it still isn’t sounding good, then I’ll finally spring for a new cartridge. Matters are not helped by the impending purchase of a new DAC either.
It’s worth understanding how tracking error works.
Using graph paper, you can measure the angle of error at different points. This doesn’t actually give you the distortion - distortion is higher towards the centre for the same angle error, due to record speed.
To minimise the overall tracking distortion, you end up with two points where the cartridge is perfectly aligned - the two point systems work this way (unfortunately, they don’t actually tell you what adjustment you need to make, but that’s another story). The difference between the two point systems can generally be understood as how much high end of side distortion they allow (which you may never hear) to reduce distortion in the middle (which you certainly will).
Really, try measuring using graph paper and plotting the displacement from the radius for the cartridge to be parallel onto said paper. It’s good practice, if nothing else.
