Big brother of the Topping TP20!
Possibly better than the Topping ........ looking at the better built and superior components used. This lost out to the Topping due to price ... and obviously my seemingly lower risk taking ability to possess goods originating from the SE.
I own 2 KingRex T20U's, they are the cream of the crop as far as tripath amplifiers go. KingRex places a lot of care and forethought on their equipment, so much so, that they even chose the type of solder for their construction, opting for lead free.
After 47 years in the hobby I finally have an amplifier that facilitates music in the way I believe it should sound. You really need to choose your speakers wisely, at least 91db efficiency and higher would be ideal. I have used less efficient ones (89db PSB Alpha B1's) but they tend to be more difficult to drive at these small wattages.
The soundstaging is simply holographic, you can even discern the height from the floor that the musicians instrument is being played.
