In my quest for Value HiFi I came across the Topping brand many many times and have read many favourable reviews. Its flagship is the TP60 model based on the revolutionary Tripath brand. Utilizing the higher power TA2022 chip, this well-made amplifier is capable of producing 80 Watts per channel at 4 Ohm, with an amazing 0.015% Total Harmonic Distortion (THD) @ 70 Watts at 4 Ohm, this truly is a refined piece of equipment. If the price tag is too much for your liking, you may want to consider other offerings from Topping below.
