It seems more and more that I'm reviewing equalization products in this column, and that such components are less often dealt with in the magazine's formal equipment reports. But it's not as if the problems created by room acoustics affect only multichannel systems. Stereophile has not ignored the topic—see the many reviews of physical and electronic room-treatment products posted on this website—but months can pass without publication of a review of such a component. Meanwhile, multichannel devotees such as I seem to talk about almost nothing else—and here's why.

New York's CE Week occurs every June and is a miniature version of the January CES held in Las Vegas. The proportional representation of serious audio gear is similar but, given the small number of total exhibits, audio pickings are usually very thin. This year, however, there was more audio buzz than ever before.

I've said it before and I'll say it again: High-end audio is the tail of the dog that is the consumer audio business. We have little leverage in determining where the technology is going, even though we undoubtedly know more about it than the average buyer. On the other hand, after the mainstream has determined where it's going (or thinks it's going), the high-end business must accept that, and try to optimize it for those of us who care deeply about getting the best sound. The ubiquitous iPod and its fellow MP3 players kicked off the playing of music files and allowed listeners to carry around their music wherever they went.

After going so far off the beaten path in my last column, with examinations of digital signal processing (DSP) from miniDSP and Illusonic and multichannel in-room measurements, this month I take a look at and listen to a new preamplifier-processor from Yamaha, along with its companion multichannel power amplifier. The Japanese company (footnote 1) was a pioneer in digital signal processing (DSP) and multichannel sound, but for a long while now has been swimming in the mainstream of audio/video receivers and home theater.

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."

I know this is a lousy picture but it doesn't matter because the important product in it, the new AURALiC Aries Music Streamer (second from the top) is a prototype and it is housed in an enclosure borrowed from the AURALiC Vega DAC (top of the stack) recently praised by JA in the February issue. The Aries ($999) is the link between the NAS where you store your music files and your USB DAC. It is the first implementation of AURALiC's Lightning streaming protocol, based on 802.11ac Gigabit WiFi and capable of gapless play of all current formats, in stereo, up to 32/384, DXD, and DSD128 as well as all common lossy and lossless formats. The Aires has built-in Internet radio and is compatible with all major platforms and many other streaming protocols, including UPnP and DLNA.

SVS showed two new subwoofers, both based on a newly-developed 12" driver that features dual ferrite magnets, a reinforced Nomex spider, a long-throw rubber surround and tinsel leads integrated into the cone to eliminate tinsel slap and improve reliability. Each is also powered by a amplifier, the Sledge STA-500, rated at 500W continuous and it incorporates a DSP engine with an array of filters, controls for volume, gain and phase as well as a frequency-dependent limiter/compressor to control driver behavior. Both driver and amp come in a compact sealed design, the SB-2000 ($699, right above) with a FR of 19-240Hz and in a larger, more powerful ported design, the PB-2000 ($799, left above). During a brief audition, even the smaller SB-2000 seemed more than capable of filling the demo room with powerful, tight bass.

It is said that good things come in small packages and this CES offered proof of this. Among the very smallest of these is the Audioengine D3 Premium 24bit DAC, priced at $189. This tiny all-metal USB DAC is no larger than the flash-drives with press kits distributed freely at CES. Still, it handles up to 24/96 and requires no special drivers. How can good sound stuff get any smaller?

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.

When I asked for something new and under $2000 at the Dali room, I was shown their new Kubik Free speaker ($1295/pair). This active compact single-stereo speaker with Bluetooth, USB, optical (up to 24/96) and analog was not exactly what I was looking for even though it did sound pleasant by itself. However, I was won over when it was demonstrated with its optional Kubik Xtra ($695) passive mate to produce some really spacious and open stereo sounds. Sure, adding the matching Sub 1 ($695) puts it over $2000 but the contribution to the sound was substantial. The Kubik system looks like and has the features of a life-style system but it is definitely a Dali.
