I was astonished by the elegant sound of this 300B preamplifier, as well by its reasonable price. There is always room for improvement for preamp with 300B tubes, a challenge which has been mastered in this pre-amp through its workmanship. This preamp exploits all the merits of 300B tubes to the fullest. Its pricing is more than reasonable given that the cost of the used materials and the crafty workmanship. It is highly unlikely that except for the Chinese mainland, there will be a factory in the current audio world that can produce a 300B preamp to such a reasonable price with similar technical specifications.
This 300B preamp hooked up with the 300B/845 flagship mono block power amplifier, drove high sensitivity JBL speakers as well as low efficiency DYNAUDIO speakers with ease and noticeable authority. The sound of violins was audible bright and the vocals were full of emotions. The dynamics and performance in the high frequency spectrum has been the best one that I have ever heard in this sound testing room.
From its pricing, Mingda MC300-PRE with the soft and smooth sound as we would expect from a 300B design, combined with extensiveness in its high and low frequency is most probably the best in his design and price class on the current market.
The circuitry of this preamp suggest that MC300-PRE follows a design philosophy best described as "Simplicity is beauty".
