Know before you buy
Yes, the Cronus Magnum III features an integrated phono stage that supports both MM and MC cartridges, allowing you to connect a wide variety of turntables directly without needing an external preamp.
No, the Cronus Magnum III does not include a remote control. It is designed as a manual, hands-on integrated amplifier to maintain its pure signal path and classic tube design.
The Home Theater Bypass allows you to integrate the amplifier into a surround sound system by letting your AV receiver control the volume for the front left and right channels. This enables you to use your high-quality speakers for both music and movies without needing to swap cables.
The dedicated headphone output is designed to provide high-quality audio performance for most standard headphones. However, because it is a tube-based design, its synergy will vary depending on the specific impedance and sensitivity of your headphones.
With 100 watts per channel, the Cronus Magnum III is capable of driving a wide range of speakers, including most floor-standing models. Its stable linear power supply ensures it maintains composure even when handling demanding musical passages.
Like all tube amplifiers, the vacuum tubes will eventually require replacement after several thousand hours of use. You should also ensure the unit has adequate ventilation space around it, as the tubes generate heat during operation.
