Luna Rouge SUT                           

Rouge SUT


Designed and built by Luna Cables in Canada 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.  

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 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.


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.



Some select vintage components are considered as the "Holy Grail" in the audio industry. One example is the original production Western Electric 300B vacuum tube. The transformers used in our Rouge SUTs were built long ago, with unique techniques and materials that are superior to what we can find on the market today. Because we are a small company we can allow ourselves to be quite selective, offering our clientele sonic qualities that are superior to anything in current production. These transformers are encased in a combination of mahogany and walnut, chosen after many hours of listening and inspired by guitar construction.

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. 




Through the manipulation of impedance, our Orange SUT 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.  


Our dye cast aluminum chassis is lined with copper, providing an excellent isolation against the environment. A high/low ratio switch allows for compatibility with a wide range of cartridges. A stereo/mono switch is also included.  


  • 4.8 Ohms primary 

  • 820 Ohms secondary

  • 1:13 -1:26 ratio

  • W-119.5mm D-120mm H-42.1mm

カナダはケベック州に拠点を置くLuna Cables。その社名を初めて聞く党人も多いのではないだろうか。それもそのはずで、今年初めて日本に上陸した2015年創業のまだ若いメーカーである。


Luna Cablesの音の秘密は、導体材料と構造にある。彼らがNeo Vintage素材というのは、最新のエッセンスも採り入れながら120年以上前のビンテージ加工機で作られる独自配合の銅線である。絶縁材にも科学物質は一切使わず、シルクやコットン、バーニッシュや天然ゴムなどが駆使されている。外周ジャケットについても自社で染め作業を行うという徹底したこだわりようだ。

コンパクトながら驚くべきサウンドパフォーマンスを発揮する昇圧トランスRouge SUTにも、前途の導体が採用されている上、独自形状のMUコアを使用。ウォルナットやマホガニーを用いたケース内部は、更に銅箔でおおわれているのがミソ。外装は削り出しのアルミ製である。

S/Nやダイナミックレンジ、あるいは音場の見晴らし等で優れた昇圧トランスは他にもあるが、Rouge SUTはそれらを踏まえた上で、さらに豊かな情感でリスナーに訴えてくる明確な説得力がある。こんなにレコードに浸れる昇圧トランスは希有といってよい。個人的にいま最も欲しいコンボだ。 By Yoshio Obara



どこにも力みの感じられない自然体の音の出方はこれまでにないものと言ってよさそうである。 By Chitake Inoue


サイズは小さいが出てくる音はスケールが大きく立ち上がりが俊敏。解像度が高まることも評価する。 By Ikuo Tsunoda
