PAUL McGOWAN Kevin in Wappinger Falls New York (wherever that is) asked me an interesting question recently. “Arnie Nudell popularized the line source loudspeaker design and many of his most revered speakers such as the Quantum Line Source, the IRS 1B, the IRS V, and the Genesis 1 (and apparently at least the two larger members […]
Steve Guttenberg writes: Ultimate high-end speakers are conceived with the same zeal Ferrari and Lamborghini apply to their no-holds-barred sports cars. Sales of ridiculously expensive and absurdly powerful cars are holding steady, and the same can be said for extreme, high-end speakers. Granted, there’s no practical reason for the existence of the new 450-horsepower Audi […]
MQA has everyone talking but what exactly is it? What’s its goals and how does it sound? Some suggest it’s the devil incarnate while others believe it’s a gift from heaven. What’s the truth? Watch Now Paul McGowan
You could do it as a Linux user. You need to login to B2 using SSH user root password brennan. You will find the music files at /media/hdd1/music. Delete what you don’t want then run Settings->Scan Disk from the front panel to let B2 know what you have done. If the above is gobbledygook then […]
A great pity I could not find more archived images. I’ll carry on looking! HP
First off, what do we mean by the term efficiency? It refers to the production of heat vs. the production of sound. Think of it in the same way you might think of fuel efficiency. How many miles per gallon does a car get? The more efficient the car, the more miles per gallon. The […]
Dip in and out HERE
The term linearity as it applies to amplification suggests a ruler-flat straight line. That is, for a given input voltage we expect a mathematical relationship with the output voltage that can be graphically expressed as a straight line. So, for example, with an amplifier designed with a gain of 10, for 1 volt in, we expect exactly […]
First of all this thread has not been put up to provide another vehicle for cyclic gainsay posting so please respect that intent. I’m just wondering if anyone has any ideas as to what might not be measureable, either at all, or readily using equipment typically used by electrical and acoustic engineers day to day, […]

Engineers don’t yet know how to measure all we can hear on a resolving stereo system but we know a lot. What are the measurements that tell us what sounds good and what does not? Watch Now ▸
Hi all Not wishing to start any sort of war here but was wondering, as I have not seen or read anything Hi-Fi related for more than 30 years, how does modern equipment compare to the better equipment from the 80’s. Has sound reproduction improved or does the older gear still hold its own. Been […]
Previously published on September 17, 2012Channa’s (formerly of Hi-Fi World and now of Hi-Fi Choice joins us as guest writer for a short series of contributions. Prologue Music continues to be within the very structure of my life. Consequently, I use it as non-background direct stimulus when I work, or equally as engrossing and positively […]
Doug Schneider writes …. On April 1, 2016, we published “Myriad Questions About MQA,” my article about Master Quality Authenticated (MQA), a digital music format for high-resolution music files developed by Meridian Audio and now spun off as MQA Limited. (Audiophiles define high-resolution music file as a PCM digital file with a bit depth and/or […]
