I saw a review for a JBL car amp that was a class 1, BCA
design. It output a ridiculous # of watts

Google coughed up this technical paper, first on the retrieval list:

www.crownaudio.com/pdf/amps/137234.pdf

What is there in this paper that needs further explanation?

I thought I was passingly familiar with most amp types.
[class A, A/ B, d, h, etc....

Does the balanced current thing work, or sound any good?

I seriously doubt that in this day and age, Crown would field an amplifier
that simply failed to work or would unconditionally sound bad, if in good
working condition. I say this somewhat advisedly, having some inside
information about the reliability of some of their parent company's OEM
power amps for automotive use.

The paper cited above outlines the basic technology, which is based on a
pair of PWM switchmode power amplifiers.
