Judging bass

When you look at the self-amplified subwoofer system of the mighty IRSV you might think it’s not a great speaker to judge bass performance of the main power amp. You would be wrong. Few systems I have owned have been so revealing of bass performance than the IRSV. Bass performance begins well before the lowest […]

Why separates?

A stew combines the same food elements as are found in a fancy restaurant’s small expensive plates: tastings that are ever so much more flavorful than their amalgam. The same can be said for most integrateds and receivers, but not because they are in one box, but because of the shortcuts taken in their design. Most […]

Purity vs. minimalism

I can’t think of anyone that isn’t interested in purity. Pure water, pure truth, pure sound. While it’s comfortable to assume that fewer obstacles in the signal path (simple is better/cleaner) leads to greater purity, it turns out that bit of common wisdom is not always correct. Take recordings for example. It’s long been assumed […]

Is hearing believing?

Did anyone else see last night’s Horizon: Is Seeing Believing on BBC2? It could equally well have been called “Is Hearing Believing”, or any or all our senses for that matter (magnetic fields anyone?). It was fascinating. The theory of “crossover” and “plasticity” between the senses – the idea that to some extent we can […]

Is PRat a real factor?

I often see reviews that mention that an amp has good Pace, Rythm or Timing, but is that really a factor? Somebody explain the term for me, please. If the music is being reproduced truthfully and accurate surely you don’t want any rythm or timing added to it? Does PRat have something to do with […]

PCB vs. point to point

Long ago, when tubes ruled and Bell Labs dreamt of sending electrons through solid materials instead of a vacuum, few consumer audio products had circuit boards. Though today PCBs (printed circuit boards) are common, back in the 50s they were rare, though hardly unknown. Over 100 years ago in 1903, German inventor, Albert Hanson, came […]

MAKING SENSE: Just because it doesn’t make sense to me doesn’t mean it’s wrong. It is simply a challenge to my worldview.

When somebody poses an idea that doesn’t make sense, my first reaction is to reject it as wrong. Over the years, I have been working hard to ignore that first impulse, take a breath, and try and discover what our differences are. Just because it doesn’t make sense to me doesn’t mean it’s wrong. It […]

ERROR CORRECTION: I recently blogged about how building a better woofer in the first place resulted in a much better sound than adding a servo to correct the mistakes of a lesser woofer.

I recently blogged about how building a better woofer in the first place resulted in a much better sound than adding a servo to correct the mistakes of a lesser woofer. It’s common sense. The same can be said for analog circuits where designing a low distortion, high speed step-response amplifier without need of feedback will almost always sound […]

REL: False clues

REL Speakers make some of the best subwoofers in the world. Owner and chief bass’ifier, John Hunter, is nothing short of a magician when it comes to setting up a system. John gets the true purpose of a subwoofer. To fill in for the main speaker. A perfectly set up subwoofer disappears. Only the main […]

Q&A LOUDSPEAKERS: What are the advantages of low-sensitivity ones?

  “Scuse my ignorance, but given the fact that Hi Fi is all about gains and losses in an endless spiral of compromises and ‘more of this means less of that’, can the Wam-gurus please explain what the benefits of low-sensitivity speakers are over high-sensitivity models? The benefits of high sensitivity over low is obvious, […]

HORN BASS

Meyer Lansky writes … I have been reading an interesting article regarding integrating bass with horn loaded speakers. www.6moons.com/industryfeatures/grandecastine/1.html ( i know its 6 moons – but sometimes in a pile of xxxx is a nugget!) Where for the sub 50Hz content a planar dipole system was utilised. Nothing new you may say – the […]

SPEAKERS: Ones to hang on to for life?

“After 9 years with my Proac Response 3s, I recently decided to change speakers. As you can tell, I’m not an upgrade fever patient. I want something I can live with for years & I think the best advice I’m gonna get will be from those who have & are still living with their speakers […]

HARBETH: An integrated amp for 40.1’s

I’m considering simplifying my system (and banking some cash) by selling off my separates (Aesthetix Calypso pre & McIntosh MC 275 MK V) and replacing them with a solid state or hybrid integrated amp. I don’t want to spend over $2,500 and would love to find something for less if it performs well… maybe vintage? […]
