Some Random Pics from Our Visit to the Arizona Audio/Video Club


Colleen and I just returned from Phoenix, where we braved a serious bit of winter weather to present the new Axis VoiceBox S loudspeaker to the Arizona Audio/Video Club. Bill Coomes, proprietor of Sweet Spot Audio in Goodyear AZ, is the first Axis Loudspeaker dealer in the United States, and he asked us to return to the AVAZ--we held a demonstration for the group a little over two years ago. The day before we left Colorado we had a snowstorm that dropped about 20 inches of powder in a single day, so we almost didn't make it. But the day before the event the sun came out and the snow started to melt, so we were fine.

I remembered this ballroom from two years ago--big, square, bare walls, tall ceilings, all the conditions that make it difficult to provide good sound. In addition, we had only a few hours to get everything set up and dialed in at the Airport Marriott. I kept looking over at the tiny Voiceboxes and saying to myself, "Big room, little speakers, and a relatively low-powered tube amplifier...sounds like a recipe for disaster." But within thirty minutes or so Colleen and I had the system assembled and playing music. Much to my surprise, the low frequencies were not only present, but tight and controlled and clean.


We brought our prototype of the Unison Research SH headphone amplifier/DAC, which is about to start shipping to the US in a couple of weeks. Matched with the Unison Research CD Primo CD player, the ADL H128 headphones and Cardas Audio Clear Light cabling, this system impressed many of the audiophiles in the room--so much so that we sold a couple of them before the show was over. We have set the MSRP of the SH at $1695, by the way.


The main system was identical to one of the systems we exhibited at the Rocky Mountain Audio Fest last October. It consists of the Axis Voicebox S speakers, of course, as well as a Unison Research Triode 25 integrated amplifier/DAC and the Unison Research Unico CDE CD player, all wired with Furutech. Since the Voiceboxes are relatively inefficient, we had to switch the Triode 25 into pentode mode for 45 watts per channel. Even in this big room we were able to achieve decent sound levels.


Just like the last time we visited, the room was pretty much full with Arizona audiophiles. I played three or four of my usual trade show demo tracks--some Three Blind Mice, some 2L Recordings and, of course, Happy Coat. Then we played a few requests. I know I'm making a few waves in the industry by talking about taking show attendees' requests, but an audiophile club meeting is different--more interactive and more casual. After we finished the presentation, many club members lined up to speak with us afterward. The AZAV has always welcomed us and treated us graciously, and we hope to return in a few months to introduce new products from both PureAudio and Brad Serhan's new company, Brigadier Audio Group.


Finally, Colleen and I snapped this selfie just a few seconds before we went into the ballroom and started our presentation. It was a great, productive trip, and you can see it in our faces. We're planning on hitting the road this May for at least a couple of weeks, and we're going to try to visit as many of our dealers as possible. We hope to do more events just like this one. In fact, this is one of the best parts of our job!

A Welcome Holiday Respite Courtesy of 2L Recordings


Last week was a rough, troubling week. Monday started off with a health scare that put me into a foul yet unstable frame of mind. The ongoing debate over the political correctness of the term "Wife Acceptance factor" became quite heated and I found myself being criticized on both sides of the argument. All of this happened in the middle of our seasonal rush, with international shipping avenues completely clogged up for the holidays, resulting in delayed shipments and angry customers. And people ask me why I don't celebrate Christmas. Maybe two decades of retail management has something to do with that.

I did receive another welcome package from Norway. Morten Lindberg sent me several 2L recordings to review, and those should appear shortly. In that care package, however, I found two discs that I've already reviewed--TrondheimSolistene's Souvenir and Flint Juventino Beppe's Remote Galaxy. I did notice that the packaging was slightly different--traditional jewel cases had replaced the older clamshell case. When I opened them I discovered that these were merely Blu-Ray audio discs--not the usual two disc set with both Blu-ray and a CD/SACD hybrid. I wasn't quite sure why Morten wanted to send these to me--I already have both of these titles in LP, CD and Blu-ray. Perhaps he wanted to emphasize a more affordable way to own these groundbreaking recordings. I put them aside for a couple of weeks and almost forgot about them.


When I noticed them once again, sitting in my stack or review materials, I suddenly remembered the strengths of each recording and how that would translate to listening on my new high-quality headphone rig. First up was Souvenir, the Grammy-nominated recording that really put 2L on the map in the US. If you remember my original reviews of this recording, you'll know that these are small orchestra performances of pieces from Nielson and Tchaikovsky that are arranged in a way so that no musician sits next to another musician with the same instrument. The result is a blended sound that will challenge what you think you know about classical recording.

With my headphone rig, which consists of a prototype of the upcoming Unison Research SH headphone amplifier, Furutech H128 headphones, a cheap Samsung Blu-ray player and Cardas Audio Clear Light cabling, it was far easier to discern these unique orchestral arrangements and pinpoint the differences in sound. With Remote Galaxy, a wildly dynamic and exciting recording, that different perspective, residing entirely within my noggin, was startling and made my heart race with anticipation more than once. (You can read my original review of Remote Galaxy here.)


Yesterday, I had an idea. I've just received the new high-efficiency (94 dB, 8 ohms) Unison Research Max loudspeakers, which were designed for low-powered tube amps such as Unison's own Simply Italy (12wpc) and Triode 25 (22 wpc triode/45wpc pentode). Needless to say, the Max goes very loud with very little power. These 2L recordings were downright ideal for such a set-up, with plenty of delicacy during the quieter moments and plenty of gusto during crescendos.

Before you know it, my troubles vanished and I starting thinking about how much I've come to love the music coming out of Norway these days. I just submitted my ten top albums for 2014 to Perfect Sound Forever, and three out of the ten are Norwegian recordings. Something tells me that if I visited Norway, even for a week, I'd come back refreshed and ready to write about controversial issues in audio once again.

Bjorn Bolstad Skjelbred's Waves & Interruptions on Blu-ray Audio


It's tough to review atonal, dissonant music in general because I feel there's a fine line between appealing to those more adventurous classical fans and throwing up your arms and saying, "Look, this is a difficult listen and you might think I'm crazy for recommending it so highly." You start talking about other aspects of the music, such as the recording quality or even the bleak moods and images that are summoned from the deepest recesses of your soul while you're listening. That's why it's such a delight to come across a recording like Bjorn Bolstad Skjelbred's Wave & Interruptions.

Sure this is challenging music, cast in that Scandinavian bleakness that comes from a culture that is characterized by somber emotions and a routine attitude about the value of perseverance. But this new Blu-ray audio disc is a huge surprise because the music is performed by such unlikely combinations of instruments--marimba and viola on the opening "Movements," for instance, or vibraphones, crotales, flutes and guitar on "Lines in Motion, Entwined." That sounds superficial, judging a recording great because you appreciate the exposure to more exotic arrangements with equally exotic musical instruments, but Waves & Interruptions opens a window into unique musical experiences, such as hearing the lowest registers of the marimba and hearing how deep the notes can reach, and how these thunderous flourishes, such as on the closing title track, can shake the floor and bounce off the walls of the recording venue. This is a marimba, after all, not a tympani.


That makes this recording such a wonderful demo disc, to be sure. As usual, Morten Lindberg of 2L has successfully mated unusual and complex music with a recording quality that underlines how instruments such as the marimba and the vibraphone and the bass flute sound in a very real space. How often do you hear these instruments out in the real world? These instruments are often used as embellishments, otherwordly touches that distinguish a piece as unusual and far from the mainstream, and to hear them spotlighted is a rare treat.

The story behind Waves & Interruptions, as is the norm for 2L, is as interesting as the music itself. Composer Skjelbred produced all of these pieces for melodic percussion--a term I really like--from 2001 to 2013, and it's a considerable coup to have enlisted the services of noted Norwegian percussionist Eirik Raude to interpret these gems. The liner notes point out the introspective tone of this music and note how they capture the shy persona of the composer, and that's perhaps why it's easier to digest the more calming aspects of this poetic music than it is to go on an all-night bender of Berg, Bartok and Schoenberg. You can crawl between the quiet spaces of the music and curl up into a fetal position, knowing that you won't jumping at sudden crashes and crescendos. It's strange music, indeed, full of tension and a weird arcane magic that still manages to be soothing in a way you might not have felt before.


This quiet, of course, escorts you deep into the recording where you will easily hear the uncommon physical links between musicians and their instruments--breathing, positioning and the tandem resonances of wood, metal and flesh. I've listened to this disc a few times now on my new headphone rig (Unison Research SH headphone amplifier, ADL H128 headphones and a simple Blu-ray player, all linked with Cardas Clear cabling and power cords), and it's quite wonderful allowing these remarkable sounds into your head. At the same time, it's even more thrilling to play this disc on my reference system just to hear these musicians exist in such an intimate yet isolated spot on the stage.

So it's another amazing sonic experience courtesy of 2L. I will go further and say that Waves & Interruptions goes one step beyond this--of all the fascinating yet difficult recordings I've heard from this Norwegian label, this one is the most accessible and pleasing, all while maintaining its place in the vanguard.

A New Headphone System and a New Rule


The 2014 Rocky Mountain Audio Fest was a couple of weeks ago, and Colleen and I wound up doing two rooms almost all by ourselves. I say almost because we did enlist the help of Cora, our friend and first CCI employee, as well as Brad Serhan, the designer of the Axis VoiceBox S speaker that we just started to distribute in the US. Unfortunately, we didn't have our usual RMAF partners--Dan Muzquiz of Blackbird Audio and Bob Clarke of Profundo. Bob had a family emergency (all is well), and Dan's son Nathan decided to get married on the same weekend. You can tell Dan's audiophilia hasn't rubbed off on his sons--when Nate's fiancee first suggested October, he should have immediately said "No way, baby...my pop's got RMAF in October." (Just kidding. Congrats to Nate.)

Anyway, I'm bringing this up because a) I haven't had time to blog in the last few weeks and b) since the show I've had a lot of changes to the system--or, more accurately, systems. All the wonderful PureAudio gear is gone to the reviewers, and I'm currently breaking in part of the system we'll be using at CES in January which consists of the Unison Triode 25 integrated amplifier/DAC and the new Opera Callas monitors. My other system, which has magically started to form to the left of my desk in my office, is headphone-based. Now I've had some headphone systems in play over the last year or so, but this one is a bit different--more ambitious, more versatile and hopefully more permanent.

This new system consists of a working prototype of the upcoming Unison Research SH headphone amplifier with DAC (the same DAC as in the Triode 25 in my listening room), a pair of the new ADL H128 headphones (backed up by pairs of earbuds from Cardas Audio and ADL), my trusty $66 Samsung Blu-ray player and--get this--my laptop. I'm going to finally get serious about jumping into the 21st century and all this computer audio stuff. I've just hooked up my laptop to the Unison DAC via a Cardas Audio Clear USB cable (all interconnects and power cords are also Cardas Clear) and I can finally listen to all those hi-rez files I downloaded the last time I tried to get into computer audio. Which, by the way, was not the first time.


Why is this time going to be any different? Well, it's sort of my job now since one of my manufacturers decided to start putting a DAC in all their upcoming products--a serious DAC for 2014, with all the bells and whistles--and now I have to answer questions about sampling rates and DSD and even double DSD, whatever that is. Secondly, the sound kicks major butt. I like it a lot. This is a very impressive system, and it makes me want to re-explore the headphone landscape like I did a few years ago when I owned an amazing pair of Grado GS-1000s with the Stefan Audio Arts cable upgrade and a Woo Audio headphone amp.

That said, I have made myself a promise for this blog--that I really need to refocus on vinyl. Over the last few years I've been getting enthusiastic about other formats. Lately, however, I've been noticing a trend: when I blog about vinyl, more people read it. There's another underlying reason for this new commitment to my favorite music format, and it's a bit of a long story. I'll keep it as brief as possible.

A few months ago I was contacted by a relatively new record label that was reissuing a lot of remastered classics--as well as some new "audiophile-quality" albums from contemporary artists--and they asked me if I would like to review some of their titles. I looked at their catalog and said sure--these were relatively fun and exciting releases. I didn't exactly specify that I preferred vinyl or CDs, but they kept referring to the releases as "albums," which to me means something you can hold in your hand. Over the next few months the label contacted me periodically and asked me if I wanted this title or that title, and the answer was always yes.

Then I noticed something--after several months, none of these releases had been delivered to me even though I was still receiving almost weekly e-mails asking if I want to review this one or that one, this one or that one. I finally asked if there was an ETA on any of these titles, and my record label contact said, "Oh, it's just taking a little more time to get the physical formats together--most reviewers just need downloads." I replied that I preferred physical formats because I also review based on sound, and that my computer audio system was nowhere near my big system in terms of ultimate sound quality. A few weeks later, the contact told me that she couldn't secure the licenses to get me these releases on a physical format. I told her that she was in luck, since my new 21st century computer audio system would make it easier for me to review downloads. I gave her one caveat: only hi-rez, no MP3.

"We only have MP3 downloads to send you," she replied.


Ugh. Sorry, folks, but I blog for fun. I don't get paid. So if you're sending me something to review, I want something for it...like permission to keep the LP or CD I've just reviewed! Hopefully my review will be worth the $20 to you. I know, that makes me sound a little whorish, but I really look at it this way--getting a CD or an LP in my mailbox from a record label or a publicist or even the actual artist and then reviewing it, well, that's a lot of fun. It's fun enough, in fact, to do it for free. But if you set up an account for me on your website so I can listen to files and write reviews from that--well, that's not as fun to me. I might change my mind once I get this computer audio system rolling, but for right now I only review LPs, CDs and other physical formats. (No LaserDisc though. Or Betamax.)

Anyway, I will be blogging about yet another personal journey into the world of computer audio...maybe this time it will stick. I'm crossing my fingers.
