ROOM TREATMENTS:

There are many multi-driver speakers, but few that go floor to ceiling like the IRSV. Floor to ceiling multi-driver speakers are called a Line Source. What’s counter-intuitive about a line source is how specific the imaging can be. With that many drivers, one would think the image would be tall, rather than lifelike, when the […]

BECOMING A SHREWDER HI-FI BUYER: Don’t be fooled by a “louder is better” decision.

A few readers have asked me to back off on being uber technical and get back to writing more about sound and high end audio from a listener’s perspective rather than a designer’s and I’ll definitely do that but I did want to finish up on our little series about DACS. One thing to remember […]

BECOMING A SHREWDER HI-FI BUYER: Part 5 – NAKAMICHI PA7 power amplifier … a few observations

A SLAP IN THE FACE: For now, I am feeling a bit selfish listening and enjoying but heck, there’s gotta be some bennies to the job!

Some years backI wrote about a new power amp technology that simply blew my skirt up to the point where I have cleansed the listening room of anything but this product to amplify the Maggies.  The decision to consider doing this took about 10 seconds: I knew immediately this was it.  I then spent nearly […]

SPEAKER CABLES: My rule of thumb is simple. Do what you can to keep them off the floor and away from any other cables.

I have seen some crazy stuff in the 40 plus years I have been around audiophiles and high-end systems. Exotic room conditioning, trinkets aplenty, cables the size of my leg, claims of subatomic effects, components that sound different depending on their earthly orientation, low-frequency waves said to resonate with the Earth. In fact, I could […]
