Sure 2x100W TK2050 Amplifier – First Impressions

Justblair

Already on www.justblair.co.uk we have looked extensively at a brilliant amplifier from Sure Electronics. The Tripath TA2024 board is a cost effective, high quality amplifier board that in stock form offers value and with a few tweaks can offer serious performance. It was with great interest that I awaited a sample of the recently released “Big Brother” to this amplifier… The Sure 2*100 watt @ 4ohm TK2050 Class-D Audio Amplifier Board (product code: AA-AB013). Well it’s here in my grubby mitts and today I managed to find some time to give it an initial listen.

Available for $39.99 excluding delivery, this board is a pocket money buy, question is can it deliver decent performance at this measly price?

TA2024 Evaluation Board Mods

In his case he started off with a Chinese made module supplied to him by Arjen Helder. This module uses the Tripath evaluation board schematic and as Aleš shows here, there are plenty of potential modifications you can do to this board to get the most from it.

In in another article, I showed how the Sure Tripath Boards unacceptable DC could be reduced significantly by removing a pair of resistors from the PCB effectively disabling Sures attempt at a DC offset reducing circuit. This article takes the modification a step further to eliminate DC offset completely.

albins_intructions I thought that I had made al the alterations to the power lines on my Sure Tripath TA2024 based amplifier modules. However over on DIYAudio.com Albin posted another suggested mod which I have to admit I was sceptical about. The modification affects the topology of the power lines on the Sure Tripath 2024.

The Sure Electronics TA2024 Amplifier impressed on my first inspection although suffered from Poor DC offset and a slightly dull sound. This is the second modification I have made which is aimed at improving the top end sound of the amp.
