Default TK2050 vs TDA7492

Hi there...

I'm thinking of buying one of these two boards:

TK2050
TK2050 50W+50W Class T HIFI Stereo Audio Amplifier Board dc 12v Voltage:10-30V | eBay

TDA7492
2 X 50 Watt 6 Ohm Class D Audio Amplifier Board - TDA7492 | eBay

In your opinion, what would be the best buy between this two? I'm considering to buy the TK2050... For a 6 Ohm load speakers, do you think the Tripath would be better? I've read (somewhere in this forum) that the voltage should not exceed 24V when using 6 Ohm speakers...

Can anyone enlighten me on this subject?

And by the way:
Are those boards well desgined? Shall I change any components for a better ones?

I've read as well that a lot of people, do change components to reach far better results... If I change some components, better results will be attained?

Many thanks in advance

I can't offer an opinion on the class T amp but the TPA7492 looks like STMicro's version of TI's TPA3118.

Should sound good.

Awww go ahead :-)
I mean how can you go wrong?
A $20 Amp from the Lower Yangtze Noodle and Electronics Factory.
Likely made out of the finest of fake parts.
A sure bet for a Winner product..
Buy Cheap = buy twice or if silly.. repeatedly :-)

I have the SURE brand TK2050 and TDA 7492 boards and thought the TK2050 sounded better with my 8ohm Advent test speakers. I also got one of the $15 RED TPA3116 boards that sounds at least as good as my TK2050 boards. It's important to have a power supply with 4amps or more at 24volts if you want to get the most out of any of these boards.

Thanks mrrgb

I think I'll go for the TK2050 board... In a couple of weeks I'll be receaving the board, and I'll post what I have found about it

By the way, do you think I should do any modifications to the board?

I'll post photos later

This one costs aprox. 32 Us Dollars:

And this one costs 20 Us Dollars:

They are both rated 100W x2 and they both need a 24V DC Power Supply

I'm not really an expert, but they seem very similar to me... Shall I go for the cheapest one?
