•Made In The USA- Hand built to the most exacting specifications in our New York Facility. All amplifiers are fully evaluated and acceptance tested using the the best audio test equipment made by Audio Precision. We perform all of the tests in a typical Stereophile test evaluation and many more to characterize each amplifier. Each amplifier is shipped with a fully evaluated test data package so that the customer can see how his particular unit performed after acceptance.
•Transferable Lifetime Limited Warranty- Our Products are guaranteed FOR LIFE.
•Completely Hand Wired- The entire amplifier is wired by hand using all American labor in NY. The wiring is all discrete components and all point to point. This provides a lifetime of serviceability and reliability. All of the wiring and soldering meets the Military Standard 2000 requirements. All operators are trained to this standard.
•Aerospace Specifications- All of our resistors, capacitors, transformers and inductive components meet or exceed the applicable military quality standards for parts selection. We use the same parts used by NASA in the Shuttle and Space Station equipment.
•Class A Design- All amplifiers are a full Class A design yielding the ultimate accuracy in music reproduction.
•Input Stage Design- The input design uses an ultra low noise tube design that yields typically a 100 dB signal to noise ratio– the best in the market. All of the overall gain is in this single stage. This significantly reduces phase distortion and yields a dynamic, stable soundstage with terrific dimensionality.
•Input Tube- The input tube can be “rolled” between a 12AU7, a 12AX7 or a 12AV7 to maximize gain and listening preferences. Each unit ships with a set of 12AU7s and 12AX7s.
•MM/MC- Selectable inputs for either moving magnet or moving coil cartridge designs
•Matching Input Transformer- The MC input utilizes a matching input transformer to optimize the impedance match between a MC cartridge and the amplifier input regardless of the interconnect cable variances.
•Loading Controls- Front panel controls allow the user to set resistive and capacitive loading to match our custom transformer input
•Voltage Meter- Illuminated front panel INDEPENDENT voltage meters allow for quick diagnosis and resolution of cartridge imbalances
•Output Stage- Our proprietary output stage design uses a 6GH8 the only one in the industry that provides ultimate signal linearity regardless of interconnect cable variances.
•Mute Switch- We have designed a front panel mute switch so that your amplifier gain does not requireadjustment between record changes
•Aviation Grade Chassis- All amplifier chassis are aviation grade aluminum with a mutiphase powdercoat and clear coat finish. The amplifier finish is absolutely beautiful and bulletproof! The front panels are machined from solid blocks of aviation grade aluminum. The entire amplifier is assembled using Military Standard stainless steel hardware for ultimate reliability and a lifetime of trouble free service. All hardware is meticulously staked using an aerospace coating to eliminate any hardware failures over time through vibration, shipping or movement. This is an assembly process honed over many years of satellite manufacturing and assembly where re-tightening hardware can’t happen.
•Internal Wiring- The entire amplifier is wired using 18 gauge Military Standard 16878 teflon coated, silverplated copper wire. This is the same wire used for the Navy’s Aegis Cruisers! Heat is the enemy of amplifier reliability. Because this is a Class A design, there is some heating of the unit which causes the wiring to age and degrade over time. Our wire never ages. The teflon coating will last a lifetime. The interior of your amplifier will look the same in 10 years as it looks coming off of the production line. The amplifier is designed using all 18 gauge wire to provide many times more the current density than can be achieved using printed wire boards or lower quality wiring.
•Burn-In Process- Each amplifier undergoes a rigorous 100 hour burn-in prior to acceptance testing. This drives out any component infant mortality problems and ages each amplifier into it’s perfect listening range.
•Manufacturing Process- All amplifiers are built using our own Statistical Process Control manufacturing processes that yield better than a 99.8% first pass yield. This is better than the airline industry’s or hospitals’ safety record. The finished amplifier is 100% reliable, tested and guaranteed for a lifetime.
•Power Measurement System- Each amplifier has a tuned, power measurement system that allows for flawless system integration and adjustment.
•Shipping- Each amplifier is shipped using a 2 box, double wall container system that has diecut, high density and low density foam vibration absorption material. This shipping system is designed to withstand a drop on all 6 box sides from 3 feet and produce no amplifier damage. We have NEVER had an amplifier returned for shipping damage.
