The Audiodigit T2020 kit amplifier

The Audiodigit Tripath T2020 amplifier kit is sold by Autocostruire, an Italian outfit. It's a easy-to-solder integrated amplifier with no SMD components, air-core inductors and a small Alps potentiometer. I put it in a small metal enclosure, powered by a wall-wart.

Note that the chip runs cool enough not to require heatsinking under most conditions.

The verdict: This is a potentially very nice sounding amplifier. Detail is excellent, power is well enough for normal home requirements, bass is natural. However, high frequencies are a bit tiring. Piano pieces sound a tad metallic. In fact, my tweaked T-Amp sounds a bit more rounded, a bit "rounder". This is possibly due to my poor internal wiring in the enclosure, power supply issues or the low quality speaker connectors, all of which are easy to tweak. And tweak I will.
It's quite likely that the T2020 comes into it's own in a power amplifier configuration with a separate active low-gain pre-amplifier. Easy enough to try out.
As it is it's brilliant as a good-enough-fi project.

Outstanding work! You keep insisting that it's not that hard, but to me it still seems like rocket science. ;)
