Pyon Sound of South Korea, led by Mr John Yoon-Sung Park, goes by the motto “We Do Not Make It, If It Is Not The Best Within The Given Limitations”. Once you look at Mr Park’s creations, you will understand what he means. His development of Picawood, a product similar and superior to Panzerholz, for use in armtubes, headshells and other pieces, shows Pyon’s commitment to eliminate vibration and resonance. It would be simpler and cheaper to make everything of plastic and metal. It would be easier to cut arm-tubes of carbon fiber or magnesium, but Mr Park chose a more difficult path by adopting a wood-based product.
His Picawood, made from individually stained, and visually inspected, wood plies, requires more time and effort than cutting a piece of metal or plastic. While machining Picawood can be accomplished on the same machines that cut plastic and metal, the alternating structure of Picawood means that the choice of cutting tools, the cutting speed, and the pressure exerted by the tools are different from those used for plastic and metal, and increase production time. Wood requires a very sharp cutting tool to prevent grabbing and gouging, and the wood fibers tend to dull those very sharp cutting tools very quickly.
With the Ultima Black Pearl turntable, Mr Park has taken time-tested approaches, like belt-drive, but radically improved their performance by using advanced technology like a brushless DC motor controlled by an ultra-precise encoder, a unique belt, and auxiliary flywheel, for a wow and flutter figure of better than .001%. A brushless DC motor produces none of the pulses, or cogging, of an AC synchronous motor, so the belt does not have to act as an isolation device. The result is high torque, high moving mass for speed stability, and ultra-quiet operation. It combines the strengths of belt drive and direct drive.
The Iris Reference Tonearm benefits from the ideal bearing created by unipivot construction, but the Iris is much more stable, through the use of magnetism and mass, than the typically unstable unipivot competition. The Picawood arm tube is lighter than aluminum, but stronger, and incredibly quiet. VTA is adjustable during playback. VTF and antiskating are easy to adjust.
The Pyon Sound isolation devices combine coupling and decoupling in one device, giving the user good stability, while isolating components from vibrations conducted through equipment racks and stands. Using one method would be easy, but using both is fundamentally important for good sound.
Pyon Sound employs costly LCR equalization in its Iris 3 phono stage, and Pyon is working on new tube electronics that will surely rank with their peers, regardless of cost. The electronics are hand assembled and point-to-point wired for purest sound. Pyon winds its own signal transformers in-house, giving Mr Park complete control over quality and specifications. The Pyon step-up transformers are state-of-the-art in appearance and performance.
Finally, tying things together to make a system, the Pyon equipment stands are scientifically correct creations that employ every tool available to Mr Park. Mass, coupling and decoupling, the only combination that works: mass for inertia so that a body at rest will stay at rest, and to lower the resonance frequency of the mechanical system; coupling to provide excellent mechanical stability; and enough decoupling for isolation, but not so much that it would upset the equilibrium. Rather than ignoring physics (and sanity), Mr Park’s creations exploit Newton’s Laws of Motion and acoustics.
By supervising the production of Picawood, by winding its own transformers, and by hand assembly and testing of various systems, Pyon Sound has complete control over quality. Expect great things from Pyon Sound. Mr Park is a person of rare insight, with the determination to achieve perfection.
