Bridging two channels of a cheap Class D amp into mono can double your power for not much cash — but it halves your load impedance too. Here's how to do it without cooking anything.

Class D amps now beat valve and solid-state on power, size and price. So why do some still sound flat? Dave Okafor explains what the spec sheet doesn't show.

Impedance dips scare buyers more than they should. Here's how to read a speaker's impedance curve and match it to an amp that won't run out of puff.

Damping factor gets thrown around a lot, but it only matters in specific, measurable situations. Here's when it actually changes what you hear.

A 15-watt valve amp and a 60-watt solid-state amp aren't playing the same game. Here's what actually happens at clipping, and why the number on the box misleads you.

Class D amps now deliver serious power for giant-killer money. Dave Okafor breaks down what you actually gain, and give up, versus solid-state and valve gear.

Why the watts-per-channel number on the box tells you almost nothing useful, and how to actually match an amplifier to a speaker without overspending.

Damping factor gets thrown around like a quality score. It isn't. Here's what the number actually measures and when it matters.
