Have you ever found some easy to understand conversion tables for compliance specs for TT's?\n\nSo far, I found that US manufacturers have been known to list static compliance numbers. Japs use the n x 10 to the power of -6 but it's at 100Hz and the EU measures at 10Hz and it is μm\/m N and not the nx10-6.\n\nMy head is spinning from trying to convert these. All the numbers I got when trying to find a good cartridge were actually wrong due to these different standards.\n\nI DID follow the link in our TT buying guide:\n\nhttp:\/\/www.resfreq.com\/resonancecalculator.html\n\nBut here it says to multiply the Japanese numbers with 1.5 – 2. which is casual enough to buy the wrong cart. Also, our guide says “Conversely, if the resonant frequency is too high (15 Hz-20 Hz range) music, warp, record noise, etc. in the lowest of audible ranges will resonate with the arm\/cartridge, also causing huge speaker excursions. If a note coincides with an audible tonearm\/cartridge resonance the cartridge can mistrack or at the very least, you’ll hear an exaggerated boom in the bass.” but the linked web page says: “It is interesting to note that Poul Ladegaard of 'Bruel og Kjaer' determined empirically that the 'best" resonance frequency would be much higher (15Hz to 18Hz) than what is normally considered desirable. See his excellent AES paper published here.”\n\nSo the ideal and mismatch overlap.
