About testing a cartridge 2016-06-01 22:11:21 I'm repairing an original needle for my Technics EPC-205CMK3 cartridge and was going to try few alternatives to replace the original (now damaged) damper material to find the best possible choice. My aim is to run some tests to help choose the final material. For testing, so far I have got one test LP (Vinyl Essentials) and have ordered another (Ultimate Analogue Test LP). My test setup is: Technics SL-Q2Technics EPC-205CMK3 (now equipped with 205CMK2 stylus).Pro-Ject phono pre-amp EMU-0404USBI'm in a learning process with this type of testing so suggestions regarding software (excl. recording software) and testing techniques are wellcome. I did ran three tracking ability (40µ - 100µ) tests (using my current setup listed above) from test LP and recorded them. Example 1st tracking ability test (files: 20s/FLAC 24/96/6.5MB each)): 40µ 50µ 60µ 70µ 80µ 90µ 100µBy the test descriptions there should be 'buzzing' noise when the tracking ability limit is past. For my ears there isn't buzzing in any of those recordings (i.e. all three tracking ability tests was passed) but, ... Am I listening these 'by the book' ? Why I'm checking this is just because of, IIRC, cartridge I have wasn't among the best with tracking ability and now the stylus is even worse than the original (boron vs titanium cantilever).
