Son-or-Filtronique was celebrating its 41st year of being in business at SSI and the retailer's larger room featured Verity Sarasto Mk.2 speakers driven by Audio Research Reference 210 tube monoblocks&#151;love those green power meters&#151;and the relatively new Audio Research Reference Five preamplifier. Source was the fully-loaded, four-box dCS Scarlatti SACD/CD player that <A HREF="http://www.stereophile.com/hirezplayers/dcs_scarlatti_sacdcd_playback_s… Fremer reviewed last August</A>. (My apologies S-or-F, but I didn't note the cables being used.) This was the last room I visited at SSI and all my notes said was "Wow!" So that's all I have to say here.

The smaller room operated by Montreal retailer Son-or-Filtronique was a little on the small side for the bass perfomance of the Sonus Faber speakers, driven by a pair of Ayre's mighty MX-R monoblocks, the midrange and highs were sweet and musical -sounding, whether the source was the MacBook seen in the photo driving the Ayre QB-9 USB DAC or the acrylic-plattered Bauer dps turntable that Art Dudley favorably reviewed in the Show (April) issue of <I>Stereophile</I>.

The affordable Monitor Audio Silver RS6 has been a long-term recommended loudspeaker at this magazine since <A HREF="http://stereophile.com/floorloudspeakers/306monitor/">Bob Reina reviewed it</A> in March 2006. The English manufacturer recently replaced its "S" series with "X" models, which feature revised drive-units, better internal bracing, and lacquer finishes. The benefits of the changes are said to be better low-frequency definition and deeper bass extension. Being demmed at SSI was not the replacement for the RS6 but the larger Silver RX8 ($1750/pair in standard finsih, $2000/pair in black or white gloss). With the RX8s driven by a Simaudio Supernova CD player and a Yamaha RXZ-7 receiver, Dave Brubeck's classic "Take Five" did indeed sound fine, with a soundstage that floated free of the speakers themselves and weighty but well-defined lows.

The Computer Audio 2010 seminar on Saturday was very well-attended&#151;I barely managed to get a seat. The presentation was by Steve Silberman of Ayre Acoustics, with technical commentary by John Atkinson. Silberman took an admirably generic and non-partisan approach, barely mentioning Ayre products, and refusing to answer the question "Should I get a Mac or a PC?" I've taken a wait-and-see approach to the whole computer audio subject, and Silberman did not convince me it's time to introduce a computer into my audio system, but I must say that he did an excellent job of describing the options, and if I <I>were</I> to take the plunge I would certainly use the information on the Ayre web site.

Although it was introduced at the January CES, SSI was my first opportunity to hear Wadia's cute 151PowerDAC mini amplifier ($1200). It combines a DAC, digital preamp and 25 Wpc power amp, and is housed in the same tiny package as Wadia's iTransport shown to its right. The PowerDAC was being used to drive ProAc's new floorstanding Studio 140 Mk..II speakers in the M-HiFi room at SSI, with XLO cables.

With so many lookalike, workalike remote handsets littering the ring-stained table of our hobby, new ones seldom stand out&#151;or work better than the old ones. Pioneer has finally produced a breakthrough: Anyone who buys a new Pioneer VSX-1020 receiver (expected to go on sale in America in June, for approximately $800) will have the opportunity to download a virtual handset from the Apple apps site, for use with his or her iPod Touch or iPhone. The finished product looks&#151;and works&#151;exactly like the knobs and switches on the amp's front panel. Here's one remote control that will probably never get lost under the couch or dropped in the toilet. (Don't ask.)

In one of the excellent-sounding Audio d’occasion rooms, I had the pleasure of meeting Oracle Audio Technologies’ Jacques Riendeau, who introduced me to the latest incarnation of his beautiful Delphi turntable, reviewed by Michael Fremer in our March 2010 issue. Riendeau explained that the Delphi Mk.VI ($11,600, with Oracle/SME 345 tonearm) uses Delrin feet for a better balanced sound across a wider environment; an improved main bearing system for a greater gap between background noise and the signal; and, most importantly, Oracle’s Micro Vibration Stabilizer System, which utilizes three plungers that dip into silicone baths to reduce lateral vibrations, found by Riendeau to have an enormous impact on sound quality.
