Balancing The Sound Scales

Appropriately named Libran because they're balanced cables, the Librans are graceful in their signal handling.

Recommended for use between the Majestic pre-DAC balanced TRS output jacks and the balanced XLR inputs of the Proprius power amplifiers.

Having a similar dielectric constant to polypropylene the Libran's insulation is a "fast substrate" making it low-loss.

Unlike polypropylene the Libran is far more flexible and will form a bend radius down to 7cm.

It is ultra-low capacitance at only 45pf/m across phases, and 75pf/m either phase to shield.

Excellent balance and noise rejection is achieved through its twisted pair construction and foil plus braid shielding which is connected at both ends.

All terminations give 360° shielding for high interference immunity.

The Libran is suitable for use in both low-impedance, and (up to) 600 Ohm balanced systems.

I've just got some GSP Libran balanced cables to go between my Majestic and active Harbeth speakers in my study system, which aside from captive leads from turntables was the last non-GSP link. The improvement over the single-ended phono cables was very apparent, with more detail and dynamics, and clarity. Definitely recommended!
