Some speaker cabinets weigh hundreds of pounds and are made from solid billet aluminum and an internal structure, like YG Acoustics and Magico. Is this kind of cabinet beneficial or overkill?

We hear about system loudness in these videos and read about it in stereo magazines but can you define for me what that actually means in SPL? And Paul gets into another riff on compressed audio. Be warned.

What are the differences between horizontal and vertical bi-amping and why would someone choose one over the other? Are there best practices when it comes to bi-amping in different directions?

We know that higher wattage amplifiers have the advantage of greater headroom and sound more effortless, but is their sound quality actually better?

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.
