Introduction
X1 Owner’s Manual
The X1 is an ultra high quality minimalist audio preamplifier that features a remote control and external power supply. It combines a completely new circuit topology with traditional construction representing thirty five years of amplifier design.
This preamplifier flows from a commitment to create the best sounding product: a simple circuit with the most natural sonic characteristics. Derived from US Patent # 5,376,899, the X1 integrates power MOSFET and JFET devices in a simple Class A topology in order to deliver the finest sound possible.
The
The X1 minimizes the number of components in the signal path, and yet retains exemplary objective performance specifications. It pushes the edge of the art in exploring how much subjective quality is obtainable with a new but very elementary gain stage.
The X1 employs a new type of volume control that offers an order of magnitude better performance than seen before in an electronic control. It provides over 60 dB of range, large voltage swing and very good measured performance. Most importantly it is subjectively outstanding; better than any potentiometer we know of. We are justifiably proud of this new device, which is registered as having a patent pending.
Very few people are involved in the production of this product. I supervise all phases of the construction, and I test each preamplifier myself. If you have questions, comments, or problems, please feel free to contact me directly.
Thank you for purchasing this preamplifier. It is my sincere hope that you will enjoy its sound as much as I do.
