One of the not-so-secret principles audio design is that no matter how good the design of the basic circuitry, the ultimate sound quality will be a major function of the power supply. Simaudio has taken this to heart with a new product that builds on the already-excellent power supplies of the Moon Evolution series. The new 820S ($8000), pictured here, can serve as power supply for any two products in the Evolution series, providing separate power supplies for digital and analog components.

I have a fondness for electrostatic transducers, and one of my early stretch-the-budget audio equipment purchases was a pair of Stax Lambda headphones. So I was happy to see the display of Stax headphones at SSI 2014. They even had one that looked like a descendent of my Lambda: the $3495 SRS-5170. My Lambda still works, but the foam inside the earpiece has deteriorated. I should get it fixed...

As reported previously in Stereophile, the Montreal Salon Son & Image is now owned by the UK-based Chester Group, but with Sarah Tremblay continuing as the director of the Montreal show. (Sarah is also the manager of the upcoming New York Audio Show.) On hand at the Montreal show were (left to right) show organizer Scott Humphrey, Chester Group Chairman and Founder Roy Bird, and Sarah Tremblay.

It's Friday, March 28, about 11 am. I'm on the Toronto-to-Montreal train, checking the Stereophile website. Art Dudley has a SSI 2014 show report posting up already! A travelogue is a good idea; I'll try to follow Art's lead. Alas, the scenery is not the most photogenic, and shooting from a moving train has its challenges. For me, travelling by train has an association with Hitchcock: North by Northwest and The Lady Vanishes. I look at my fellow passengers; none of them bears a resemblance to Cary Grant, Eva Marie Saint, or Margaret Lockwood. There seems to be nothing sinister going on.

What can you tell about the intrinsic sound quality of a loudspeaker if you've heard it only at an audio show? Arguably, not much. If it sounds bad, there may be a number of reasons for that, only one being the speaker itself. It may be the acoustics of the room, problems with speaker setup, poorly matched associated equipment, insufficient break-in/warm-up, or poor choice of demo recordings.

The design and manufacturing of loudspeakers can be described as falling on a continuum. At one end, we have speakers that use off-the-shelf drivers purchased from driver manufacturers, combined with crossovers based on information in standard loudspeaker design cookbooks and/or loudspeaker design software (perhaps with "voicing" that conforms to the designer's preference). In the hands of a skilled designer, this approach can produce good results—but they can't claim any originality.

At the other end of the continuum are speakers that are designed and built from the ground up,, using design principles that, while perhaps not entirely original, represent substantially new application of these principles. This approach is much more rare—and much more costly to implement.

The Muraudio Domain Omni ESL ($48,000/pair), which made its debut at TAVES, is squarely in the latter category...

Turntables were much in evidence at TAVES, perhaps the most impressive being the TechDAS Air Force One, which had two versions of the famed Graham Phantom Elite arm mounted. Bob Graham himself was on hand, and can be seen in the photo. Bob demonstrated the vacuum hold-down of the turntable, the audible resonance of the LP when tapped being silenced when the vacuum was turned on. Impressive. The worldwide standard price of the Air Force One is $100,000, and the Phantom Elite arm is $15,000, but Bob said that since he's also the distributor of the AirForce One, he can offer a "deal" on the package price.

No, you're not accidentally visiting www.motorcyclistonline.com. With some out-of-the-box thinking, Suave Kajko, President of the Toronto Audio Video Entertainment Show (TAVES), and Simon Au, Vice-President Sales of TAVES, approached Harley Davidson Canada about exhibiting at TAVES 2013 this past weekend, and the HD people agreed to participate.

What does this have to do with audio or video? Well, the top-of-the-line Ultra Limited Harley ($30,000) includes an "infotainment system," with all kinds of audio/video goodies, including surround sound. Here it is, with Suave looking suitably...suave (Sorry!).

Is there a country that, per capita, has produced more major loudspeaker brands than Great Britain? The British brands that immediately come to mind are Tannoy, KEF, Bowers & Wilkins, Quad, Rogers, Spendor, Harbeth, Castle, Acoustic Energy, ProAc, Monitor Audio, Epos, Celestion, Lowther, PMC—and Wharfedale.

Few topics ignite more heated arguments among audiophiles than the price of audio equipment. How much do you have to spend to get really good sound? Are people who buy expensive gear wasting their money, or is it simply a matter of getting what you pay for? There are many such issues, most of which have been discussed at length in Stereophile and various online forums; here are a few I haven't seen addressed except in passing.
