DC (DIRECT-COUPLED) AMPLIFIERS üAC COUPLED SMALL SIGNAL AMPLIFIERS ADVANTAGES: 1. Signal, load and the amplifier bias are separate. One can work on the bias calculations stage by stage w/o worrying about an interaction with the signal source or the load. 2. No dc current flows through the load or through the signal source.

In fact the first fully DC coupled amplifier was the Crown DC300 which had a frequency response flat down to DC which is 0 hz. Love ’em or hate ’em they were introduced around 1968 and many are still working just fine while a lot of their competitors of that era notoriously bit the dust.

You can also use a cheap Chinese class D amplifier or module, probably something based on IRS2092 if you want 300W. All you have to do is increase the value of the input coupling capacitor, you can solder an electrolytic cap in parallel with the existing cap. If you want to go down to DC, then an amp based on IRS2092 will do it if you remove the input coupling cap.

Please consider our award winning EX-P7 to match with the stereo power amp EX-M7. Our amplifiers are Direct-DC-Coupled without any capacitors in the signal path. This yield less colouration, high resolution, fast, and transparent sound quality.
AC vs DC coupling: What is it? – Noise Engineering
https://noiseengineering.us/blogs/loquelic-literitas-the-blog/ac-vs-dc-coupling-what-is-it
A DC-coupled input is pretty simple. Here’s a really basic, not-interesting schematic that illustrates the point. There’s an input going to an op amp and then right out through another jack. The output on this circuit is DC coupled. A DC-coupled schematic. Of course, we need the contrasting AC-coupled example, too: An AC-coupled schematic.
