Descriptions:

The 6M-300B mono-blocks come with two models - a single 300B single-ended Class-A 8W model and a more powerful dual 300B Class-A push-pull 21W model, which is designed to work with a wider variety of loudspeakers. The 6M-300Bs have all the benefits of mono-blocks in terms of better channel separation, wider soundstage, minimal cross interference thus more quiet background. The 6SL7 and 6SN7 in the front-end are chosen for their sonic characteristics. They provide the desired match for the 300Bs, giving rise to the overall tonal balance and sound quality that the designer set out to achieve.

The hand-wound audio transformer is specially made for the 6Ms with proprietary technology. The audio transformer, coupled with the 300B output tube(s) produce excellent linear response within the full frequency range. The underlying circuit is designed with ?true balanced? capability in mind that will be implemented in a follow on model in the near future.

The front-end utilizes a 6SL7 for input/gain, and a 6SN7 for buffer/driver and phase inversion. For the 6M?300Bse (single-ended model), the 6SL7 can be replaced by 6SN7 if higher gain is desired. The 6Ms are designed to emphasize sonic characteristics of tubes used, thereby, producing unmistakable "tube" musical playback experience. This design allows audiophile the flexibility of experimenting with tubes of different makes. The sonic difference will be more pronounced and immediate.

 The 6Ms feature negative feedback via a selector in the front panel with "min" or "max" settings. The min setting has zero feedback while the max setting provides a -3.5db feedback. Zero feedback can be characterized by its forward, airy, and well delineated mids. It's well suited for vocals and strings. The max feedback results in a deeper and wider soundstage and is more dynamic. Each mono-block has an individual volume control. The 6Ms can be used either as power amp or as integrated amp by way of Line or Direct inputs. Note that there are two RCA jacks for each Line and Direct inputs to accommodate bi-wiring practice if so choose.
