....do not understand why there are not more commercial LM3875 offerings."

Possibly because it would be hard to charge audiophile prices for an amp revealed to be based on an inexpensive DIY friendly 20 year old power op-amp chip. There were at least a few audiophile companies way back when that sold LM3875 based amps for around $3000 +/-.

A few may still exist possibly using a newer chip. Sakura Systems only charges $10,000 for their chip amp. I wonder how many they sell. 47 Labs, Musical-Laboratories (defunct) also come to mind, and others that are now out of business.

The modern "Easy Button" for audiophile amp design has gone the Class-D OEM module route.
