the smoothness is a reflection of the low distortion.  Miyajima cartridges are effortlessly musical too.  Paul Rigby reviewed the original Takumi \u003cstrong\u003e\u003ca href=\"http:\/\/www.theaudiophileman.com\/#!miyajima-takumi\/c1xbf\" rel=\"noopener noreferrer\" target=\"_blank\"\u003ehere\u003c\/a\u003e\u003c\/strong\u003e, and gave it a 'Groovy' award.\u003c\/p\u003e","brand":"simco-audio","offers":[{"title":"Default Title","offer_id":44493023838343,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/4886\/8487\/files\/inifinty.jpg?v=1776447674","url":"https:\/\/simcoaudio.com\/products\/infinity-mono-mc-cartridge","provider":"simco-audio","version":"1.0","type":"link"}
