These guys
http://www.tripath.com/
Have developed a new amp circuit called Class T. It allows for
extreme efficiency (95% in some cases) and potential for reducing
distortions significantly.
Oh, and there is a class T amp out now, with 15 watts a side, that
people like the sound of, that costs 30.00 (USD)... !
http://www.si-technologies.com/frontEnd/cm_productDetail.jsp ?productID=18
Tape Op reviewed it recently and while they didn't throw their
other amps in the trash, they did like it. Now, a 30 buck amp that
sounds good is cool enough, but what is really cool is a 300.00
amp that kills 2K amps and puts out 1000 watts. This is where
the Class T technology seems to be leading.
Yes, this will show up in our industry.
Anybody seen/heard any Class T stuff?
DC

There's quite a bet of techie info on the Tripath site, but it is at
the component level.
That's all I know of.

My first impression is that there don't have nearly enough rail voltage to
make these high output, but that might or might not be indicative of
capabilities in the future. Could be that the die is just not stout enough..
could be it's not stout enough.. yet.
Something to watch for.
If I was going to test one of these, it would be the TDA1400 w/o a doubt.

I am not a circuit guy, but couldn't the inherent efficiency of
the class T circuit (up to 95%) make up for this? Doesn't it
require less voltage on the rails to do the same work?

Not exactly.. you will still need more voltage to swing the AC current up
and down. Effeciency has no affect on that variable... It's about Peak to
Peak voltage. Less voltage P2P IME has meant less wattage out.
To support this (possibly dated) information, I have been into a load of car
audio amps, and one of the first things they do is step the voltage (through
some kind of converter be it a dc to dc or a tesla coil setup) to a more
respectable number. There is a cost in efficiency this way, but that's how
it works in those designs.
9 - 11 volts makes this amp suspect, however they could be onto something
I'm not aware of.... which is why I'd start with that chip and bang on it
and test it's thermal output qualities also. Perhaps it's stepping up
internally and doesn't need a large rail voltage?
hmmm....

I'd love to see what you found experimenting around with one
of their chips.
BTW, they have a 100 watt (@8ohms) amp that runs on 60v
rails. Does that sound reasonable?
I bet they'd sample you one...
