Witam. Mam prosbe. Otoz ponizej przedstawiam garsc danych technicznych bardzo taniej wkladki MM Ortofon 320U. Czy ktorys z szanownych forumowiczow-vinylowcow moglby skomentowac te dane. Moje zdziwienie wzbudzil fakt, ze w tak taniej wkladce igla ma szlif "fine line". Czy warta kupic te wkladke za 150 PLN ?
