Masterpiece Edition Phonostage

Masterpiece Edition Phonostage

Designed around the Ref Phono 1 but taken to a completely new level.

The Masterpiece Phono stage uses an existing incredible design and applies the same level of component, internal wiring, tube  and connector upgrades that only apply to the Masterpiece collection.

Both the Masterpiece Pre-amplifier and Phono stage use simple signal path topology where every signal component is chosen for it's absolute quality and construction. Internal wiring uses the same ultra high purity silver wire as used in the Ref interconnect cables. Signal capacitors are replaced with V-caps CuTF Reference grade units and resistors with Charcroft Z foil. Rhodium plated connectors and power inlet socket are standard. Power supply capacitors are the excellent Mundorf tube caps for ultimate power supply delivery and all pub's are mounted for micro vibration absorption and dissipation. Vacuum tubes are also dampened.

Masterpiece Edition Phonostage features :

  • Charcroft  Z foil resistors in the critical signal path for low noise and a more natural sound.
  • V-Cap CuTF  signal path capacitors.
  • Lundahl MC step up transformers (SUT) using amorphous cobalt core and dual coil structure with Cardas high purity wire.
  • Silver internal wiring and Rhodium plated RCA connectors
  • Toroidal transformers with B+ regulators for low PSRR figures.
  • High amplification, super accurate RIAA EQ , low output impedance and low distortion.

All cabinet construction is made with Bolivian rosewood and a copper top panel with additional damping.

Available with built in Lundahl amorphous core SUT's for MC cartridges or as a seperate custom built SUT in Bolivian rosewood.

MC1

MC1

MC1 - Tube Phono Preamplifier

Designed around the legendary 12AX7 vacuum tube in a 3 stage amplification stage using 2 x 12AX7 tubes for gain and the third for a buffered output to achieve lower impedance and better drive capability.

As with all out products the quality of components is always of the highest standard.

Mundorf silver/gold oil capacitors are used in the signal path and Dueland Coherent Audio cables used for all internal wiring along with high quality RCA connectors for purity of signal transmission.

MC1 features :

  • Free lifetime modification to MM or high output MC
  • Built in SUT'S
  • Enhanced and perfected RIAA EQ
  • Mundorf silver/gold oil signal capacitors
  • Duelund oil/cotten internal wiring

This model is primarily a MM Phonostage with built in SUT's for typical MC use, how-ever for MM or high output MC cartridges a free modification is available to convert this to any cartridge and associated impedance and capacitance for perfect compliance.

SE model comes with Miflex copper paper/oil capacitors and Duelund silver internal wiring.

Ref Phono 1

Ref Phono 1

Our flagship phono stage pre-amplifier is handcrafted in Scotland with the best audio grade components and based around a dual mono design for the audio circuitry using hand picked 6922 tubes and an extremely low noise power supply based around the excellent 12X4 vacuum tube to produce very low PSRR figures and near zero ripple current.

The result?   A sense of space and texture with breath-taking musicality, three-dimentionality and dynamics.

Based around purity of design and signal path our Ref Phono 1 uses a combination of  audiophile components only seen in esoteric models.

Ref Phono 1 features :

  • Kiwame resistors from Japan in the critical signal path for low noise and a more natural sound.
  • Mundorf paper and oil signal path capacitors or upgradable Dueland Coherent Audio capacitors.
  • Lundahl MC step up transformers (SUT) using amorphous cobalt core and dual coil structure with Cardas high purity wire.
  • Silver internal wiring and CMC RCA connectors
  • Toroidal transformers with B+ regulators for low PSRR figures.
  • High amplification, super accurate RIAA EQ , low output impedance and low distortion.

Handcrafted in beautiful hardwoods and available for demonstration in our showrooms.
