Just another Venerable Ta 2020 chip in a Flashy box.
At usurious pricings imo.
From the innards photos: A YJ at $15 is 'at least' it's equal.
Should be, as it uses Better quality bits/caps.
But No fancy extruded box nor Audio Weenie approved connectors.
I've a few Ta 2020's by now.. they are addictive... at less than $20 and/or $5 for the chip itself (delivered)

Replace the input caps AND use your ears, is best I can say.
I've experimented with $$$ ones and with Cheap 1$ films from the Local Chinese electronics shop. These cheapies Sound Better on the setup I experimented with.
Markedly better in fact. Very sweet, detailed highs. Curious result but well received.
Caps can/should be used as voicing tools.
What works best on someone else's setup ..does not.. necessarily work well / best on another. Cut 'n Try is required.

Inductors? Those supplied are of reasonable amperage, But as stated, replacements are easy and inexpensive experiments. I found no audible advantage.. But?
Output caps can be bettered for inconclusive results :-) YJ uses Wimas Does the K Rex?
Charge pump cap ..Should.. be a Good film and foil IMO, Fit one.
Dunno about the massive Power cap uf 'upgrade'.
It has proven of elusive improvement for me.
Real easy 'upgrade' though.
One day I will try the twin 180uf's as suggested by Tripath (what would they know?) using Decent Film Foils. That could be interesting.
G'luck
Ohh .. remember that this Ta2020 chip Will Not better a genuinely decent 'Old Skool' Amp sound wise. Despite all bleats to the contrary.
Maybe in the next generation or 2? chip designs.
