Over the past decade, Silbatone has dedicated tremendous resources to designing and refining very ambitious tube phono pre-amplifiers. We think the phono preamp remains foremost among challenges for the designer and continues as the promised land of the art of music reproduction, yet in general, the field lags behind other areas of audio in innovation and evolution. It may be a digital world but for really deep listening, many here in attendance still turn to analog, as we do. We believe that phono is still the soul and conscience of specialist audio, the reality check.
 
Our newest entry in the stable, the SQ-103 is a phono-only pre-amplifier incorporating various refinements that emerged in the course of our R&D programs. The new SQ-103 features a new twist on JC Morrison’s transconductance amplifiers using the German Post D3a. The all-important input stage sets the noise figure of the entire system and does much to establish its character. This first stage can swing 45V and the gain window is optimized for headroom to lessen record noise. The phono EQ is craftily incorporated into the input stage circuitry as opposed to a separate lumped filter stage driven by the input stage, as found in most non feedback, RC and LCR based preamps. This topology minimizes series components and enhances the dynamic and nuanced presentation we have come to expect from the D3a transconductance circuit. ADC servo on the 6900/7044 buffer is used to avoid coupling capacitors enroute to the transformer output.
 
The SQ-103 is built to high Silbatone standards. A handsome and heavy milled chassis provides a non-resonant foundation for the electronics. Input (1:10) and output transformers (600ohm) are super quality pure silver wired models that we have relied on for years. Two MC and Two MM inputs are supplied with front panel push button selectors. Single-ended and balanced XLR outputs are available on the back. No muss, no fuss - just high performance.
 
For those who wish to experience the leading edge of phono pre-amplifier performance, Silbatone invites you to audition the SQ-103, a perfect partner for our line amplifiers and integrated amps, and a gateway into the magic of high-end phono reproduction in the 21st century.
