Rogue Audio Cronus Magnum III - Integrated Amplifier - Black - Made in America - priced right in Australia - drives Magnepan beautifully



The award winning Cronus Magnum has garnered an enviable reputation in the high end audio world. Even at its attainable price, it outperforms other integrated amps costing many times more. The pure tube design provides a smooth, almost liquid sound that has made this amp a reviewer favorite. With circuitry borrowed from our most advanced amplifier designs, the Cronus Magnum's 100WPC effortlessly reproduces even the most demanding musical passages.

The Magnum III features a number of exciting new upgrades.For vinyl enthusiasts the phono section has been completely redesigned to accommodate both 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.

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.


From a technical standpoint the Cronus uses a triode preamplifier coupled to our excellent Atlas Magnum power amplifier. A large oversized linear power supply stores tremendous energy for low frequency response and dynamic headroom. The tube circuitry is cutting edge with short signal paths exacted in a low noise design. Finally, precision components are used to provide the transparency and air that are so critical to accurate musical reproduction.

Cronus Magnum III and Magnepan .7 Loudspeakers - Stereophile Magazine, Feb 2020  Excerpt:


AMG Giro Turntable, DS Audio E1 Optical Phono Cartridge System, Rogue Audio Cronus Magnum III Integrated Amplifier, Magnepan .7 Speakers, Wireworld Cables

Julie Mullins  |  Feb 13, 2020



On Sunday morning I eased into my rounds with the Musical Surroundings folks: In conjunction with local dealer Sweet Home Audio, they presented a sweet-sounding, straight-up analog setup that featured several products at (relatively) more affordable price points than is sometimes the case.


If it isn't apparent by now, I'm kind of a sucker for good design and gear with aesthetic appeal in addition to (of course) good sound. So yeah, I was loving the made-in-Germany AMG Giro belt-drive turntable with its shiny sapphire blue base/plinth of machined aircraft-grade aluminum in a "double circle" configuration with a white platter made of a proprietary synthetic material. (This was a special edition; it also comes in black and other color options.) It uses the same decoupled spindle design that's found in AMG's higher-end Viella V12 turntable.

The DS Audio E1 optical cartridge system consists of the DS E1 cartridge ($1250USD) and DS E1 phono preamp/equalizer ($1500USD) with minimal filtering. The cartridge has an elliptical stylus mounted to an aluminum cantilever and a new wire suspension for increased channel separation. The optical sensor is placed closer to the stylus than in prior DS cartridges, and there are no lasers used in this model.

A 100Wpc Rogue Audio Cronus Magnum tube integrated amplifier powered a pair of Magnepan .7 planar-magnetic loudspeakers to pleasing effect, with wide-open soundstaging, substantial midrange, more low-end extension on bass lines than expected, and wonderfully natural sound on John Prine's "Fish and Whistle," to name just one selection. Maggies are often considered among the best bargains in hi-fi, though placing them properly in the room can be tricky. Setup requires a little extra care and finesse-which was clearly done well here.

A couple of other German-made turntables were on static display, the Clearaudio Performance DC Wood model for one-and for those who desire top-tier performance and ease in record cleaning, the Clearaudio Double Matrix Professional Record Cleaner ($6000USD) appeared to be a beautifully machined and well-engineered contender."
