Default What's the current state of the art chip amp?

I have some parts left, including a transformer, and active filters on the way... so...

I was wondering: what is the current state of the art chip amp? what chip, inverting or not, regulated or not, snubberized...
My gainglone is working nicely since nearly 2 years, and I haven't keps myself informed of what has been done in the "chip amp community" since.

Alex

Alex, that's too long...
Things have moved.

Best results so far for me:
Improving the Non-Inverting chipamp

With this PSU:
LM338 regulated snubberized PSU for audio amplifiers

Yeah I know it's been a long time...

I haven't followed the discussions about NI, T network, buffers, regulated psu, LM4700 and other chips, and snubbers

Best is of course relative & very speaker dependent...but a lot has happened in 2 years...

Not trying to dis, but why are you so big on that design? I agree that the design is somewhat elegant in that the same rails power chip and tube, but once you cross the line and add a 2nd tranny for the tube, I would think there is so much more you could squeeze out of that tube. I mean, at least add a CCS

I did say development of

higher rails on the tubes, CCS on the bottom of the follower as a minimum... shunt reg for the tube & regs for the chip amp are also a good idea.
