What's inside

ELECTRONICS

Retaining possibly the world’s best control, the ALPS RK50 allows you hear every detail with such life and realism. Bespoke circuit design and components allows faithful reproduction with limitless headroom and dual mono amplifiers directly scaled down reference models have the ability to drive all loudspeakers comfortably.

And not forgetting our vinyl roots the built-in phono stage is the same as our award winning Pulsus phono stage. The passive RIAA circuit using high-end capacitors, helps maintain linearity of reproduction and not wanting to limit sound quality we have installed its own 35va mains transformer giving independent power to each channel. Fully flexible for any cartridge with gain and resistance easily adjustable.

POWER SUPPLY

A colossal 1100VA transformer and huge capacitors totalling 132,000uF, give an electrical reservoir the prodigious reserves that allow you to hear the slam and low frequency of live music, whilst retaining control to unearth detail and subtilty you have never before experienced.

CASEWORK

A dominating piece of audio sculpture, commanding attention with our logo carved into the 20mm solid aluminium front panel, there is a feeling of engineered solidity that is also expressed in the sound reproduction. The heavy gauge steel chassis and cover offer valued screening against environmental noise so that even the smallest musical detail is revealed. The logo hole patterning and SIGSUM name are majestically displayed for that final touch of elegance.
