Located in Kelowna, British Columbia, Resonessence Labs is the maker of the Invicta ($4000) described as a "technically excellent, audibly superior, Next Generation DAC." I can't comment on all these claims, but the Invicta is clearly a highly versatile device, with a wide assortment of inputs, including an SD card reader (FLAC, AIFF, and WAV on SD, SDHC, and SDXC cards), HDMI video output to show playlists on a TV monitor, and no fewer than seven digital filter options.

Resonessence Lab, based in Kelowna, BC, is a company making cutting-edge digital equipment. The top of the line is the Invicta Mirus ($4995), a D/A converter that uses 8 DACs per channel, and handles DSD64/128, DXD, and claims THD of 0.0002% (–114dB). In true trickle-down fashion, it has been joined by the Invicta ($599), still with the same DSD/DXD capability, and THD only a slightly less impressive 0.00032%. Their latest product is the Herus headphone DAC ($350), this one with THD a whopping 0.003% THD. They're shown right-to-left in the photo.

“What’s new?” is the question that comes up first with established manufacturers when considering whether there’s something worthy of a blog item. In Polk Audio’s case, the answer was “Everything!” According to Polk rep, Jim Crowley, their entire home audio line has been revamped, with changes in the cabinetry, drivers, and crossovers. Perhaps the most significant change is that now, for the first time, some Polk speakers feature a midrange driver. And with all that, Polk loudspeakers continue to be reasonably priced: the pictured LSiM is a modest-by-audiophile-standards $4000/pair.

While the model designation might lead one to think that the new entry is a Beryllium-tweetered version of the F208, the F208Be is actually a new design, with new drivers and a higher-end crossover…

Revel's well-received Performa series of loudspeakers has been completely overhauled, with a number of advances in materials and manufacturing technologies. The new Performa3 series now consists of 10 models, including three floorstanders, two stand-mounted monitors, and various home theater speakers. The drivers are all new, and, according to Revel's Kevin Voecks, they have exceptionally low distortion, which contributes to clarity and transparency. This was very much in evidence with the pair of M106s ($1700/pair) and F308s (at $6000/pair, the most expensive speaker in this series) that I listened to.

The Stereophile Ask the Editors session at Shows—in which John Atkinson (left), Art Dudley (center), Stephen Mejias, and I fielded questions from the audience at SSI—in something that I enjoy a lot, and so, I know, do JA, AD, and SM. Through the years, I've learned that it's almost impossible to anticipate what the questions will deal with. And that was certainly true this time. The questions covered a wide range of topics: why are there so few active speakers on the market; why doesn't Stereophile review more vintage equipment; what system that we've heard (at the show or elsewhere) represents to us audiophile nirvana; music recorded in what format will be reproducible a thousand years from now; why is the interest in high quality audio less popular now than it was a few decades ago; has loudspeaker quality improved through the years; and many more. All thoughtful, interesting questions.

John Atkinson opened Saturday afternoon's "Ask the Editors" session with a brief introduction in French—which got applause from the audience—but the rest of the session was conducted en anglais, and the quality of questions from the audience was easily up to best that I've experienced at such sessions at the Home Entertainment shows. The questions covered a wide range, dealing with topics such as the cost of producing LPs and SACDs, advances in loudspeaker technology, the sonic quality and pricing of cables, how to allocate resources in assembling a system, and discussion of what systems had particularly impressed us at the show. I think I can speak for John Atkinson, Wes Phillips and John Marks (as well as myself) in saying that we had a good time and were most impressed with the level of interest and dedication to good sound showed by the audiophiles participating in this event. Here's a picture of the Stereophile crew, taken just after the "Ask the Editors" session (from left to right): John Marks, yours truly, Wes Phillips, and John Atkinson.

One of the characteristics of shows like SSI, where many of the exhibitors are dealers rather than manufacturers or distributors, is that you may get a chance to hear equipment combinations you would never encounter at CES. At SSI 2015, the Totem Earth speakers were combined with McIntosh electronics, to good effect. Another thing that distinguisher these dealer-exhibitors is that you can buy the products on display—something that's strictly forbidden at CES. The Totem Earth has a list price of CAD$9000/pair, but you could have it a "show special" price of CAD$6000/pair...

Montreal audiophiles are a hardy lot. Last winter, the city experienced the most devastating ice storm in its history, with power lines demaged to the point that almost the entire city was plunged in darkness. At the time of the 1998 Festival du Son et de l'Image (aka the Montreal Audio/Video Show), residents were still recovering from the effects of the storm. Did this calamity stop the show? No way! By all accounts, the 1998 show was the most successful in the event's 11-year history. I missed it myself, but I made sure that I wouldn't miss the next one.

For some time now, I've been thinking that my record player was due for an upgrade. My Linn LP12 turntable and Ittok LVII tonearm are about 25 years old, and my AudioQuest AQ7000nsx cartridge is going on 15. During that time, my listening has become increasingly dominated by CDs, but I am not yet ready to give up on LPs. Updating my LP12—for which I have Linn's Lingo power supply but no other upgrades—would involve installing the Keel subchassis, for $3250—for which price I could get another maker's new, current-design turntable and still have the LP12 to sell. The Linn Ittok can't be upgraded, and its replacement, the Ekos SE, costs $4950—out of my range. AudioQuest no longer makes cartridges. Examining my AQ7000nsx's stylus under a microscope showed no visible wear, and there was no obvious audible problem that could be traced to the cartridge's suspension, but age must be having some sort of effect. Taking all these factors into account, I decided to replace my entire phono front end.
