When developing the Hybrid-Acoustic Circuitry that we first introduced in our MD 309, we knew we were onto something. In the 2-channel audio landscape, there was always a separation between those who favored the precision and sharp detail that is characteristic of many solid-state products, and those who preferred the natural sound staging noted by the lovers of triode-driven devices. But there were trade-offs. Short tube life, compromises in sound-quality or cost considerations neccessitated a difficult choice by audio lovers. So when we got to work in our design lab, we pushed for a novel approach.
