The Signature 300B amplifier is much better than even the best factory version (A50). Smoother sounding, more detailed, bigger sound stage.
There are different factory versions of Reisong A50. The cheapest A50 has a smaller power transformer and components are soldered on the PCB. The more expensive A50 has a stronger power transformer and components are soldered by direct wiring (point-to-point). We are not comparing the our Signature version with cheaper version of A50. No. Our Signature 300B amp sounds better than the most expensive version of A50.
The price of the Signature Version is still very affordable because the premium parts come from our own supply. You may visit our demo room to hear the difference with your own ears.
