Class T amplifiers are similar to class D except for one thing. At low output levels the mosfets that do the switching are switched at up to 1.5MHz or 1,500,000 times a second, this improves the sound quality as the carrier frequency is way above the audio frequency being produced. If you like you get many more & more accurate samples per second which are fed into the filter on the output of the amplifier which hopefully smooths things out & you get a nice sound in your speaker (hopefully ). At higher output powers class T amps switch to a lower switching frequency to improve efficiency because there are losses in the mosfet switches (nothing is totally instantaneous).

A class D amp (generally) uses a fixed frequency to switch the mosfets so at lower volume levels they may well not be quite as clean as a class T amp.. Of course all this depends on the switching frequency of the mosfets, if you can switch them very fast then it's quite possible that a class D amp will out perform a T nearer full power but not be quite so good at low volume levels..

These things i bought look interesting, i only saw them today but as soon as i did i went into research mode.. As i have a pretty decent understanding of the subject i came to the conclusion that these were extremely good value for money with the possibility of very good performance indeed

For £37 delivered i'm more than willing to take the chance seeing as i understand how they work A little calculation reveals they should be good for 200W RMS into 8 ohm & heading for 400W RMS into a 4 ohm speaker load with a +/- 60V supply Of if they were bridged 800W RMS 8 ohm

They'll be getting bigger heatsinks all the same The control IC is good for +/- 100V though, so if the correct mosfets were used for switching each amp module could be good for well over 500W RMS 8 ohms as long as certain other components were upgraded, that'd be 2KW RMS bridged into 8 ohms with both amplifiers
Cheers Mark I look forward to hearing how they perform I finally might of found a DIY project to try fot myself
