Bridge will give you twice the voltage swing which is roughly 4x the power, so about 20w.
I haven’t yet made the bridge configuration, but it’s in the queue of things to do, and measurements will follow.

You're correct, of course. I just thought it might be fun to try something a little different. The idea I'm playing with is to also add a B1 to make this project into a small integrated amp.

of course , if that amuses you .....
there is somewhere in start of the thread , buried iteration with plenty volts in PSU

Yup, sorta. One of my daughters is living in NYC and could use a stereo, and I'm looking for an excuse to build something. She's in no rush (which is good) and whatever I build should be relatively low-powered. This might be a summer project. I thought a souped-up ACA would be fun.
ZM:
Yeah, I'll start going back over the thread. My plan is to build something with an internal power supply (probably with a 24V rail) instead of using a brick, and it's been a while since I read the entire thread for ideas/insights.
Jim:
Uhm, a dumb question: would a bridged version of the ACA require different MOSFETs? In other words, wouldn't the polarity of the circuit have to be reversed on one of the pcbs?

two identical pcbs - you feed them (through XLR) with two antiphase signals , taking output from hots
read F4 User Manual for specific details , same principle

Scott - I'm thinking several concurrent conversations / queries on that subject just might pique the interest of "management" to the possible market demand for such a little gadget.
Of course there's an interest in a circuit like that... Find me somebody to design it and we'll talk! 🙂 🙂 🙂

Forgot to install them since the pre-production kit I had didn't have any. I'll re-photograph when I get a chance.
Use them.
Use them.
Low output impedance does not automatically mean good amplifier sound. There are many other parameters that make an amplifier sound wonderful.
Is this a case of judging an amplifier by reading paper specs
rather that actually listening to it? 😕
