Over at T.H.E Show at the Flamingo, and surrounded by booths offering all sorts of discs and their supporting paraphernalia, I came upon Darin Fong's table of laptops and headphones but he was not selling any of those. His company, Darin Fong Audio, is offering a software program called "Out Of Your Head" which reprocesses stereo and multichannel sources so that you can hear them as you would over a loudspeaker-based system. This is similar, in intent, to the marvelous Smyth Realiser that I reviewed in November 2010, but, at just $149, is much more affordable. Like the Smyth, it supports multiple presets (acoustic environment files) although it is not personalized to the user's own HRTF. It was also quite effective. There is free trial version on the website.

A decade or two ago, I stumbled on a surprising demo room at an audio show. I don't recall most of the equipment, but I do remember a pair of Paradigm Studio 20 speakers at one end, their crossover entrails dangling free, connected to the rest of the system by a multiplicity of wires. At the other end, among the usual electronics, was a PC whose screen was a crazy quilt of graphs and menus that constantly twinkled in response to the ministrations of DEQX's Kim Ryrie. He seemed totally absorbed, but looked up and proudly offered to show me what he was doing. When I told him that I was familiar with the Paradigms, he played some music that sounded just fine. Then he clicked his mouse. The sound was transformed from the familiar to the fabulous. I was dumbfounded. "What have you done?"

I had been with Stereophile only six months and feared my tenure was over—I thought I was losing my hearing. There was pain, ringing, and stuffiness. I couldn't listen to anything.

I was getting bored with my own opening question asking exhibitors do you have anything that's new for under $2000. For two days, I was getting either a gleeful "Yes!" or a slow "No but . . ." Mike Manousselis, Director of Marketing for Dynaudio USA, surprised me with a new answer: "Well, we have something that is not new but it's price is new and it is now under $2000."

At the Las Vegas Convention Center, Dynaudio was showing—and playing—its new self-powered MC15 mini speakers. In three setups, they were connected to a laptop, a gaming console and an iPod dock, each setup clearly indicating that its high quality sound was an improvement over the usual powered computer speakers. Sporting a 6" woofer, an Esotec soft-dome tweeter (with 1st-order crossover at 1.5kHz), and a pair of 50W amps, this $1299/pair package, including elegant table mount, would be even more suitable as the basis of a deskop system with a good disc player.

While on-wall/in-wall systems were ubiquitous at CEDIA, the in-room speakers stood out for their imaging and sound quality. Even the tiny Dynaudio 2.1 system consisting of a pair of Contour SR speakers ($2200/pair) coupled with the Sub 250 ($1k) made sounds that many bigger installations would envy. Add another pair and a Contour SC ($1900) to fill out a 5.1 system that can do music as well as movies.

I have been a proponent of methodical modeling and room analysis as aids in setting up audio systems and rooms. They work hand in hand: Modeling predicts a feasible room arrangement, and analysis, along with careful listening, determines how close the outcome is to that predicted. Of course, there should always be another round of modeling to see if the current setup can be improved with more work. The spiral continues, toward, one hopes, perfection.

Late in the day at the Show, most glasses were filled or in the process of being emptied. This stack on the BG stand, however, was empty. It had been erected to show that Radia's new 210i Active Subwoofer is almost totally vibration-free in operation. At the time I took this picture, this sub, with its opposed 10" Kevlar drivers and 500w BASH amp was pumping out gobs of bass, cleanly and tightly. I could detect no vibrations at all with my hand. What's the point? Well, you can put something on top of them (vase, planter, cigar humidor!) without exciting spurious vibrations. Heck, you could even put this $1500 sub in a cabinet, if that suits your needs.

Back in the 1990s, I lusted mightily for the large ESP speakers with their tall, slim shapes and their angled driver panels. A large-room demo of the Concert Grands with Sonic Frontiers electronics still reverberates in my memory. Unfortunately, just as I evolved to the point where I could consider buying a pair of Concert Grands, the company folded its tents. Recently, I heard a rumor that ESP might be returning, and an email exchange with founder and designer Sean McCaughan has confirmed the good news.

Because I'm suspicious of just twiddling knobs to make the sound "nice," I didn't rely solely on my ears when I used the Z-Systems rdp-1 that I review elsewhere in this issue for speaker and room contouring. Instead, I used the ETF speaker/room-analysis software from Acoustisoft to help me manipulate the equalizer properly. This program can measure the first-arrival, on-axis speaker response, as well as the room response with its early and late reflections and its resonances.
