Masterpiece Edition Pre-Amplifier
Masterpiece Edition Pre-Amplifier Masterpiece // Pre-Amplifiers Description Designed around the MV2 Pre-Amplifier but taken to a completely new level in terms of component specification, vacuum tube choice and internal wiring to give an even better sense of musical involvement and resolution. The Masterpiece Edition Pre-Amplifier has an extremely simple and pure signal path with only 1 output capacitor and 1 shunt resistor on the Khuzmo stepped attenuator which have been replaced with the incredible V-cap CuTF reference capacitor and a Charcroft Z foil resistor. This along with 5N solid silver and FEP fluoropolymer signal wiring gives this Pre-Amplifier added realism and an even better 3D soundstage capable of competing with the very best equipment in the world. The choice of Linlai Global Elite vacuum tubes also elevated the sound field beyond the previous Black Treasure tubes. Design specifications include dual mono power supplies with each channel supplied by it’s own high voltage and filament rails via a tube rectifier and feeding separate regulators to give incredible stereo separation. Bespoke designs available on request. A very simple but pure signal path based around the 6SN7 audio tube and using a single output capacitor which can be specifically chosen for it’s integration to solid state or valve amplifiers based on input impedance compatibility.

Masterpiece Regis
Masterpiece Regis Masterpiece // Speakers Description After many years of building the hugely popular and successful Regis Mk1 and knowing that due to the discontinued bass/mid driver, I would have to design a new model and try and succeed in raising the bar in terms of overall sonic qualities. No mean feat because the Mk1 is truly a reference loudspeaker in many ways. The Regis Masterpiece was born from the desire to build a cost no object reference stand mount loudspeaker and choosing 2 very high end drive units from well respected manufacturers, namely Morel and Raal. The top of the range Morel copper sleeve bass/mid driver is exceptional in every way and the Raal ribbon tweeter is possibly the best tweeter in existence and also used in the Voltaire lll and new Opus One. Internal wiring, cross-over components and Rhodium plated pole connectors are chosen specifically to match these particular drive units and honed to match this design perfectly. Complimented with Mundorf’s “Angel hair” internal wadding for damping properties which significantly increase the auditory spaciousness of music reproduction. These loudspeakers are capable of the most incredible holographic presentation, high resolution detail and bass depth defying their size. These reference monitors will continue to extract more resolution and quality no matter how good the ancillary equipment is in terms of cost or quality.

Masterpiece Opus One
Masterpiece Opus One Masterpiece // Speakers Description With Opus One, we are proud to share our newly designed flagship loudspeaker. Many years of collaboration with Purifi Audio’s legendary drive units coupled with a Real precision ribbon tweeter has enabled a significant quantum step up from everything we have built before. Opus One establishes new benchmarks in musicality, transparency, and fidelity along with testing our limits of dynamic speaker design with a constellation of exotic technologies, techniques and materials. Expressed in immaculate execution in every little detail from distressed hides and exotic hardwoods to engraved panels and de-coupled to the rest of the world via an isolation platform. A timeless piece of art in your living environment ready to engage the soul with a beautiful portrayal of musical expression and to create something unique in balance between art, craftsmanship, technology and performance. The combination of Purifi Audio Ushindi technology bass/mid motors and the Raal ribbon tweeter are able to employ lightning-fast precision and deliver exquisite whisper-quiet musical passages or thunderous bass completely free of distorting cabinet resonances. Dual 8″ passive radiators tuned to the cabinet volume offer the perfect way of enhancing bass energy without the inherent problems with ports or transmission lines. Cabinet construction begins with an inert baffle of 50mm thickness and employing a fully braced design througout. Often the biggest problem with loudspeaker design is its inability to decouple itself from the floor and also other extraneous airborne vibrations. The perfect solution was an existing design which has already won many awards in its own right and able to completely remove the passage of deleterious vibrations both to and from the speaker cabinets. This impart a serious improvement in soundstage and bass precision. For those wishing to experience the visceral thrill and lyricism of the best loudspeakers in the world should audition Opus One.

Masterpiece Edition Turntable
Masterpiece Edition Turntable Masterpiece // Turntable Description Another exciting project and product development is based around the well known Swiss made Lenco turntable which fundamentally is constructed extremely well with a precision motor and structure that lends itself to be upgraded and modified to create an incredibly good turntable. The initial phase involves a complete strip down of every component with certain key parts replaced or modified. The main chassis is resprayed and lacquered before re-assembly and lubricated for longevity and noise reduction. Because the central spindle and platter are already of a very high standard and tolerance, these are polished and retained. The main bearing is either replaced with an upgraded bearing or modified with a new ruby ball bearing and thrust plate. The main motor is stripped down and inspected for wear or noise, re-assembled and lubricated. I have yet to find a motor which has failed these tests or brought back to a new standard. The high mass plinth is a based around the natural qualities of certain hardwoods and their abilities to exhibit very high levels of resonance and damping control as well as high density and other acoustic characteristics.. This model is made from solid sections of Bubinga hardwood which is incredibly heavy and dense, perfect for reducing micro vibrations within the motor and main turntable structure. This combined with Tungsten carbide ball bearings on Panzerholz dampening feet ensure the combined structure of the turntable is virtually free from extraneous effects and vibrations. A choice of tonearm boards made from either the same hardwood or Panzerholtz is available with additional dampening and specifically chosen for their acoustic characteristics and density. Days of sanding and preparation are done prior to a high gloss lacquer finish with further wet sanding, buffing and final polishing before final assembly and soak testing. A choice of tonearm is also available and from SME, Ikea and Reed along with a select number of cartridges from Phasemation of Japan. Please get in touch to discuss this product.
