BWSunderstood many years ago that a preamp must not degrade the source signal regardless of its switching, amplifying or buffering duties.

Refining circuit design and selecting the best parts have re-defined the musical performance and are the signature of BWS components. Whether a digital or analog source, the BWS line-stage preamp delivers maximum signal transfer and unparalleled musicality. The BWS line-stage is a Class A design for today's dynamic digital source components. Audiophile qualities such as transparency, pitch delineation, intertransient silence, tonal accuracy, control, dynamics and effortlessness have been design goals in the development of the BWS line-stage.

Built with minimal internal wiring,point-to-point execution and an exotic parts selection,BWS has reached new levels in life-like sound reproduction. In the mold of "form follows function", the BWS preamp uses isolated contact switching for left and right inputs to ensure the most direct signal path. The RCA jacks are gold plated oxygen-free copper. The dual mono circuit implements matched pairs of instrument grade, 10-turn volume pots to maximize channel separation and to dial-in a perfect balance.
