PR-01
Pre Amplifier

Radically reduced design, attention to detail and extensive listening trials make the PR-01 preamplifier an exceptional instrument for both enjoying and understanding music – minimalism follows consequence.

The Preamplifier "PR-01" is available in two high-quality surface finishes: anodized silver and anodized black.

Design Details

Design

• Extremely sturdy enclosure, CNC-milled from a solid block of aluminium

• All surfaces are glass-bead-blasted and then anodized with a highly resistive ceramic coating

• Power supplies mounted on suspended sub-chassis to mechanically isolate them from the audio circuits

• Extremely reduced circuit design with parts chosen in extensive listening tests

Components

• Parts are manually channel-matched to close tolerances and hand-soldered point to point

• Custom made Industrial Precision Potentiometer

• Oversized choke-regulated power supplies and custom made power transformers

• Cryogenically treated internal OFC copper wiring

• Lundahl input and output transformers galvanically isolate the amplifier from the outside world

Usability

• Precision volume control providing accurate channel synchronization and sensitive volume adjustments down to the lowest volume ranges

• Inputs with different sensitivity allow proper matching of both today’s and vintage audio components

• The ON/OFF switch of the PR-01 can also switch the Power Amp → turn on/off the whole system with one switch

• Widely used, reliable tube types ensure future availability
