Signature KT88 SE Amplifier (upgraded REISONG® A20) (12-month warranty in the Philippines)
The Signature KT88 amplifier sounds much better than even the best factory version of A20. This one is smoother and more detailed sounding.
There are different factory versions of Reisong A20. The cheapest A20 has a smaller power transformer and components are soldered on the PCB. The more expensive A20 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 A20. No. Our Signature KT88 sounds better than the most expensive version of A20.
The price of the Signature Version is still affordable because the premium parts come from our own supply. You may visit our demo room to hear the difference with your own ears.
