Some headphone amplifiers include a feature not commonly found in modern DACs and speaker based two-channel audio systems: crosstalk cancellation. What is that and why wouldn’t it be included?

We’re certainly familiar with the superiority of dual mono power amplification, so why doesn’t the same apply to preamplifiers? This viewer doesn’t see any on the market and wonders why.

Paul’s spoken about the amazing resolving abilities of the Infinity IRSV but most people will neither get to hear a pair nor be able to own one. What other speakers have this ability and are any affordable?

There is a sealed box and ported design speakers and then there’s a rare type we don’t often hear of anymore called a transmission line. What exactly is this design?
