Luna Rouge SUT                           


        Luna Rouge SUT                           

Our new Luna Rouge moving coil step up transformer is the result of many years of research and development. 


The stereo-mono switch is useful for cartridge set-up and allows the listener to enjoy their entire vinyl collection as they want it.


The Luna Rouge SUT provides a holographic sound, rendering complex warm tones and rich timbres with a most detailed, natural, and musical flow. This SUT allows your MC cartridge to express itself in a way that most active MC stages can only hint at.  


Designed and built by Luna Cables in Canada.

The design of the Rouge SUT serves to maximize the potential of an outstanding vintage transformer. Built in the 50s and 60s these transformers are becoming increasingly rare. Luna Cables has stock-piled them to make the Rouge SUT available for many years to come.  The transformers are encased in solid mahogany and walnut, then triple shielded with copper.

Why using a vintage transformer?

Some select vintage components parts are considered as “Holy Grail” in the audio industry. A good example is the original production Western Electric 300B vacuum tube. Why people are looking for an original part?  Because it is not possible to reproduce those products exactly today due to the specific qualities of the materials and production techniques used. It's the same with the vintage transformers we use. The sonic qualities are simply superior to anything in current production.


Why using two different woods?

The use of two different woods to encapsulate the transformers is based upon many hours of listening test and was inspired by guitar construction.  The combination of walnut and mahogany produces just the right tone.

The chassis and the bottom plate are carved out of a thick and solid aluminum block and lined with copper. This process provides an excellent isolation against the environment.

”Despite my high expectations, I was unprepared for the bold performance delivered by the RED SUT. Richer, more fully realized tone and timbre - more muscle and blood - more fine and hidden detail than I’ve experienced previously. RED delves deep into performers’ technique and intent - their very humanity. It will change you as a listener.”

Through the manipulation of impedance, the Luna Cables Orange Step-Up transformer will add gain without noise or grain.  When compared to active head amps, it delivers lower distortion, particularly in higher frequencies, allowing for a richer and more refined sound. Greater resolution allows for a more elaborate soundstage, with accurate placement of instruments not only left-to-right, but front-to-back as well. The step-up transformer is a necessary tool in the quest for the best sound using a moving coil cartridge.
