All in all, the Grado Opus3 is a first-class cartridge that I can heartily recommend to anyone setting up a medium to high-end turntable ensemble or upgrading an existing system.

When it comes to the Opus3, there are a few “firsts”. This is the first cartridge built with a maple wood housing, as well as the first to use what we learned with our high-end cartridges at such an entry-level price. The housing is a new shape but still keeps the wood working in tandem with the cartridge inside. This is also the first cartridge built specifically with the Timbre Series in mind.
