Ortofon Rondo Blue

Ortofon Rondo Blue Moving Coil Cartridge

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.
