AD1862 DAC IC directly connected to OPA541 power amplifier opamp

At your risk. Loudspeakers will be possibly damaged if the volume potentiometer in the negative feedback loop of the amplifier open-circuits. Have the pleasure of meeting again with Panos. He is driving his speakers in an impressing way with the signal path shown in the title. Just 2 ICs connected together, doing away with many op-amps normally found in a DAC, (digital to analog converter unit). The only op amp conected directly to the current output of the OPA541 IC is a power amplifier in itself, impressively directly driving, loudly with huge bass the speaker(s). Panos also brought to my attention the Sanyo LA6510 portable audio equipment power amp IC and the UPC2500D car power amplifier IC operating at single rail 12V. Panos was brief on one transistor (electrons flowing all the time, ie class A operation) power amps such as the Pleiades 2N3055, a one transistor radio found on youtube etc. We discused a bit line array full range column speakers.
