Paul shows us the behind the scenes of speaker designs as we unveil the new PS Audio AN3 loudspeakers. These are the very prototypes that will be traveling to Chicago’s Axpona show in April so our extended hifi family can get a sonic glimpse of what they can expect when production is finally ready.

In part two of our series Paul shows us how the 4-way speaker system that was Arnie Nudell’s reference model sounds when broken apart into its 4-elements: tweeter, midrange, mid-bass, and woofer.

PS Audio has been on the trail of building a line of loudspeakers using the design and sonic principals of Infinity System’s founder, the late Arnie Nudell, for years. Now it’s time to unveil the system and show our viewers how we built them.

Part two of Rabbit Holes discusses when it’s time to call it good with a stereo system and how to know when good enough is good enough.

Some speaker cables cost thousands of dollars and the most expensive ones have fancy and exotic looking metal control boxes attached to them. Are they to hide the snake oil or do they actually do something?

How much do the clocking systems in digital audio affect sound quality? Paul answers this sometimes technical question as simply as he can.

Many people believe the systems in their automobiles outperform those in their homes and, for some, that is likely true. But why?

We’ve all seen the old bass and treble controls on vintage (and sometimes modern) equipment. What do they actually do and how should they be used?

If your system isn’t delivering what you hoped for in sound quality should you add a subwoofer or a preamplifier?

What happens when a power amplifier is at maximum output level and there’s not speakers connected? Is it dangerous or alright to do?
