Once upon a time using a dummy head for stereo recording was all the rage. What happened to that technique and does it work?

Optical cables have one big advantage: total isolation from their connected source. Does that mean their use is the best digital interconnect in a high-performance system?

Our rooms are as important to a good reproduction of sound as our equipment. So if the proper room treatment is not to over damp it, sucking the life from the room, how come this fellow’s stereo system bucks that rule?

It seems to this viewer by the descriptions of sound he reads that most audiophiles surely must be whacked out on pot. Is it true or is that just a myth?

Vacuum tubes are the original amplification devices. How do they stack up against modern solid-state transistors, especially in audio systems? Paul gives us the real scoop.

Gold CDs, HDCD, XRCD. We read about all these different technologies and mediums yet CDs are CDs. Right? Paul explains the differences and why they matter.

MP3 files are lossy. This means they have lost information in an effort to reduce file size. Can we hear this loss? If we compare lossy files with lossless files, is there a difference?

Vacuum tubes are considered to sound “fatter”, “warmer” and generally “softer” than their solid state counterparts. Does that mean they sacrifice resolution for sound quality?

The late Arnie Nudell developed what he believed sonically killed his greatest creation, the Infinity IRSV and the Genesis 1. Did he do this? And if so, how do they work and will there ever be a commercial version available for sale?

The Infinity IRSV has 36 tweeters, 12 midrange drivers per channel. How are these many speaker drivers divided up? By frequency? Amplitude? Tasks? Paul gives us a quick tour of one of the greatest loudspeakers ever built and sold in the world.
