Ortofon MC Rondo Blue

The Rondo Blue cartridge sound is defined to be more expressive and will distinguish higher from lower pitched instruments- yet well controlled by the influence of wooden material.

The Nude FG 70 diamond is here mounted on a cylindrical aluminum cantilever again revealing a very flat frequency response passing 20 kHz including very high tracking ability at recommended tracking force of just 2, 3 gram.

We find the sound picture will tend to suit customers liking orchestral music as well as smaller groups of instruments like chamber music smaller choirs and solo instruments.

Recommended load- depending on volume or dynamic in music might be around 50 Ohm or even lower.
