Externally, the Luxman CL-1000 is similar to the classic Luxman C-1000 model - but, according to the company, the device has radically changed its circuitry. The core of the Luxman CL-1000 is the LEKUTA transformer unit (Luxman Electrically Controlled Ultimate Transformer Attenuator), which uses 34 positions.
The Luxman C-700u preamp inherits the versatility and high sound quality of the C-600F, but has a higher gain: 12 dB versus 10.5 dB for the C-600F. Externally, the C-700u is similar to its fully balanced older brother, the C-900u, but does not have a symmetrical circuit topology, despite the presence of XLR connectors.
The Luxman C-10X preamp is designed in a fully balanced concept, from balanced input to balanced output. The component is equipped with a turn-off tone block with high and low frequency adjustments, as well as a channel balance control.
Luxman CL-38uC tube preamp is attractive not only for its vintage look, but also thanks to Luxman's traditional technologies of the highest quality, including transformers for MC cartridges. Top-notch sound: open, fast and strikingly authentic, especially in the midrange.
