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 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.

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.
