MAESTRO Tube Preamplifier (2017)
The Maestro preamp will sit in between the PRELUDE and our flagship CONDUCTOR.
It features two 6U8 (One each per channel), and the same but enhanced excellent tube power supply and phono stage (100X) design from the PRELUDE.
It will provide to those who would like more gain/drive than the PRELUDE for matching their speakers/amp, but to maintain a one-box solution. With one powerful 6U8 per channel, the MAESTRO will easily yields a 10X Gain, which doubles the gain of the PRELUDE of 4-5X Gain. It will be using direct coupling design, which see the lowest possible phase shift. With the pentode section of the 6U8 use as the input amp and the triode section for impedance matching and cathode follower. We are happy to announce this will be a very low distortion pre-amplifier, this is as good or better to the famous legendary M-7 design. With one more tube than the PRELUDE and slight more complicated circuitry, we decide to offer using an optional DC power supply stage to lower the working noise further for those who thought it is needed, which benefits both line stage and the phono stage. Further distinguish to the Prelude, the MAESTRO is classic design over the hybrid design on the Prelude - the MAESTRO line stage does not have any transistors making it more pure analog sound. But it will also drive all kinds of amplifiers well be it low powered tube amplifiers or high powered solid state amplifiers.
To those who are not familiar with this tube, it is commonly used for studio and broadcast tasks, in USA and Europe. We like it over the 6922 because it has the same brilliant highs, but with even better mid to low reproductions in our opinion. There are also plenty of authentic NOS supplies too.
And did we tell you there are at least 5 tubes you can use as well : 6U8s, 6BL8/ECF80, ECF82/ECF802 and 6GH8...etc.
Same as the PRELUDE, there will be a 12BH7 or a 12AU7 for the regulating duty, both tube will sound different and safely exchangeable, but the 12BH7 will last longer due to the fact it's a bigger/more powerful tube.
