I am impressed by the TI amps, even being "feedback before the inductor" types. My only experience with a Tripath amp is the little TA2024, which is ok, but not enough power to really judge. Sometime I'll have to hear some of their more powerful types.
I have a couple of Icepower amps and some Hypex UCD amps, also extremely nice amps. UCD is probably the most ingenious amp circuit I know of, elegant and effective;
But the TI amp is rather amazing -- that they could come up with an amp design that sounds this good and is this powerful -- with all semiconductors in one chip -- is something I'd never have thought possible. Add to that the built-in SMPS design like authlxl's and suddenly power amplifiers become much more reasonable to deal with. There's really no point in using a passive crossover anymore, power amp channels and power supplies make multi-amping a no-brainer. Authlxl, I also like the +/-15 power supply outputs provided on your amp, that will come in very handy for powering the active crossovers -- how much current can that supply, by the way?

Revise and finished bi-amp module
We have found some shortage for the previous mdule,we revise and make it as bi-amp module.
Include one 550W/4ohm/1%THD+N class D amp(300KHz-400KHz PWM frequency) and one 50W/8ohm/0.5%THD class AB amp.suit for active speaker amp,class D drive woofer and class AB drive tweeter.
We have manufactured two times,total 200pcs,no problems found,when the FLB circuit use high quality capacitor,output wave good(THD/POWER and THD/FREQUENCY) in audio range.
Class D amp can be set as 200W-550W/4ohm or 100-300W/8ohm.
