Rogue Audio Cronus Magnum III Tube Integrated Amplifer

The new version of the Cronus Magnum features several significant and exciting upgrades along with a new triode/ultralinear switch.

MM/MC Phono Cartridge Compatibility

For vinyl enthusiasts the phono section has been completely redesigned for mm and mc cartridges. Two gain settings provide for 45dB and 60dB of gain so you can now use either high or low output cartridges. The phono also has five individual load settings so you can fine tune the phono for optimal results.

A Triode/Ultralinear switch allows for on the fly switching between Ultralinear operation and pure triode. Ultralinear offers the most power and a commanding grip on the bass while triode provides a slightly softer and more romantic sound. You choose which works best in your setup - maybe both!

RH5-Derived Headphone Amp Circuitry

A completely new headphone circuit is based around MOSFET buffers capable of massive current sourcing. The design is basically a simplified single ended version of our RH-5 headphone amplifier and puts out enough power to drive the most difficult headphones for clean crisp personal audio.

The line stage has been improved and has an amazingly low noise floor for a completely black background for your listening.

Finally, a machined aluminum metal remote completes the upgrade.
