TNT-Audio has been on top of the cheapo ($39+) T-Amp phenom for a while now (check out our rundown on Tripath amplifier mania), so it's only fitting they publish a showdown between a few of the different DIY Tripath options out there.

TNT-Audio pits the granddaddy of the Tripath world, the Sonic Impact T-Amp, against the Autocostruire 2020-m, the 41HZ AMP-3, and, finally, the DiyParadise Charlize. Really, the article is less about which is better (given the discrepancy in prices) than simply showing the different ways one can mod class-T amps.

And even if you're not into modding, you should check out the article. As TNT-Audio says, "Unless you already own very expensive amplification, you will probably find the class-T's a significant upgrade...and with the cheapest costing not much more than a CD, there's no excuse not to!"
