Howard Popeck writes: Only a mini test for this one I’m afraid. My notes from that time are not very comprehensive. Anyway … Built in 1978, the Gamma V is a very sensitive and selective rack-mount style digital tuner. It cost around £400 when new, as best I can recall. Construction is all frame and […]

PAUL S writes: I have encountered the best sound quality ever from a tiny vacuum tube power amp (single ended triode) driving a single driver crossoverless wide-banner loudspeaker. The only limitation: no wall & floor shaking bass and limited overall SPLs – but perfect for near-field listening. JOE writes: in my opinion hybrids make no […]
Mr. R writes … Terminations are only required for bundling odd shaped, large or solid conductors, or pre terminated for people that have trouble terminating conductors them self. Use indeed spades, these allow much, much higher contact pressure than banana’s. But, any stranded conductor fitting straight into the terminal of the amplifier or speaker: go […]
PAUL writes: Reconstruction of a sine-wave based on only two sample-point is only possible because the “algorithm” was told to construct a sine-wave! Neither a square-wave, nor a saw-tooth wave etc! However music is characterized by more or less steep transients being only captured and reproduced when using DSD as you mentioned, Paul, for those […]
I can’t begin to count the number of times I’ve written the abbreviation, Hz—1 kHz, 1,000 kHz. It is, of course, short for Hertz. The car company? Heinrich Rudolf Hertz was a German physicist who first proved the existence of electromagnetic waves. Invisible forces that had a specific periodicity (frequency) that later were named in […]
Many of the sounds we hear every day are entirely fabricated by engineers to persuade us to buy things. Hundreds of items have their acoustics deliberately tweaked to make us happy – according to Trevor Cox, professor of acoustic engineering at the University of Salford MORE
Macbooks and Windows computers cannot reproduce DSD audio files unless you know the secret. Paul shares with us how to get them through the system.
ERIC writes … I think most folks would be shocked to find out how much stuff comes from China. We’ll all find out soon as these tariffs kick in. China has the rep. of making lousy products but that isn’t always the case. If a US company contracts for a product, manufactured in China, to […]
DOUG writes … Bob Carver had a circuit he called the digital time lense that was supposed to help with CD harshness. It sounded like an eq to me overall, and I never used this feature as a result. Other things claim to improve Mp3 files. Not for me they didn’t. Your suggestion of replacing […]
Hi Neil. A bit of confusion here re the two brands. What’s their connection – if any? Ivor. Wikipedia states the following: International Radio and Electronics Corporation (IREC) was established in 1947 by Clarence C. Moore, an Elkhart, Indiana minister. The company started out building rugged, open reel tape recorders for use by missionaries in […]
FP writes … The beauty of buying home-audio gear from reputable companies that allow their prospective customers to have a 30-to-45-day in-home audition is that the customer can’t really go backwards because they can do a direct comparison with their current piece of equipment…whatever that might be…& decide for themselves whether the new piece is […]
I am always fascinated to watch those slow-speed nature videos where you watch flowers open and plants grow. Or, the opposite. A high-speed camera that slows down the wing motions of a hummingbird so we might see what in real life we cannot. Those cameras (both film and video) are essentially digital: frame by frame […]

Christian Diestl writes … A company based in Bexhill on Sea, in Sussex, England that took over the manufacture of Lumley branded loudspeakers after the demise of Reference International. LL was formed in 1998 by John Jeffries but sales were slow so he decided to concentrate on his other 2 businesses, namely a high end […]
First published in 1988 Richard Vandersteen doesn’t look like a typical loudspeaker designer. True, he wears glasses, but his presence suggests a longshoreman or somebody who’d be played by Gene Hackman. And sure enough, he tells you in a quasi-Dukes of Hazzard drawl that he’s been a construction worker, plumber, truckdriver, and electrician. Electronics had […]
Hi everyone, Is there anyone of you who had the chance to compared the Manley Shrimp preamplifier vs. the Jumbo Shrimp? I saw that two tubes where added in the Jumbo version, plus the remote and its potentiometer. Is there any influences on the sound from one model to another. Thank you, Sébastien Continues HERE
Wilko Johnson is famous for two things; firstly his contributions to one of Britain’s most respected band’s R&B bands of the early 70s the celebrated Doctor Feelgood, they did more than anyone to establish pub-rock/R& B and to put life back into a jade rock scene just before the emergence of punk. The liaison was […]
