I'm of two minds in this debate, because there seem to be significant defects in both arguments presented above. I feel that Consumer Electronics Shows are an excellent place to encounter interesting products, products that are good prospects for reviews. And sound quality is one way to decide which manufacturers to interview, which products to pursue. The CES also provides a unique opportunity to get technical clues from the designers whose products sound good; given the plethora of exhibitors, there's a tendency not to check out the rooms that sound bad. So I…

Although inclined to mood swings bordering on the manic-depressive, I am generally a very patient, tolerant person, willing to accept and overlook the foibles of those less perfect than myself. But even my incredible equanimity has its limits, beyond which the milk of my human kindness curdles, becoming as lumpy as last month's yogurt.
Perhaps I have just grown tired of certain kinds of mindless idiocy. Perhaps I am, in fact, growing shorter in tolerance as I grow longer-sighted. But if, perchance, you should engage me in casual conversation or intense technical or philosophical…
The companion loudspeaker to Denon's RCD-CX1 SACD/CD receiver is the SC-CX303 ($1200/pair). The SC-CX303 is a ported two-way with a 1" soft-dome tweeter and a 5" carbon-fiber–cone woofer. Denon claims a sensitivity of 86dB and an impedance of 6 ohms. Instead of a formal frequency response, Denon instead gives an unreferenced figure for frequency extension that, at 35Hz–60kHz, is neither helpful nor credible.
Each SC-CX303 comes with a port plug of open-cell foam; after a certain amount of experimentation, I used these all the time. The cabinet measures 11.6" high by 6.9" wide by…

I measured the Denon SC-CX303 primarily using DRA Labs' MLSSA system and a calibrated DPA 4006 microphone. The SC-CX303's claimed voltage sensitivity is 86.0dB/2.83V/m; my estimate of this was 85.6dB(B)/2.83V/m, which is within experimental error of the specification. The Denon's impedance is specified at 6 ohms. In fact, the speaker's impedance (fig.1) dipped slightly below 6 ohms in the lower-midrange and midbass regions, and remained above 10 ohms in the low treble; it's really an 8 ohm load that will not make serious current demands on the partnering amplifier…
Roy Hall has been Creek Audio's US importer for more than 20 years. Did you know that all Creek gear is now made in China? Just like Cambridge Audio, Quad, and many B&W models. Just like some US speaker brands, for which virtually all parts are made in China but are assembled, it's claimed, in the US. Three cheers for brands like LFD, Rega, Sugden, and Harbeth—all still made in the UK. For French marques made in France. For Italian products produced in Italy. Etc.
Cambridge Audio has been manufacturing in China for more than a decade. Its parent company, The Audio Partnership…
With my venerable Advents connected to the dac25.2's headphone output, I thought the sound of Internet radio was splendid. Same with my Audio-Technica ATH-AD700 headphones: splendid but not stupendous. What can you expect from Internet radio? One thing I didn't like: Turning off the dac25.2 produced a squeak, followed by something between a speak and a pop. Unplug your 'phones first. Turn off your powered speakers. I heard no such transients through the dac25.2's fixed-level analog outputs; this problem seems to affect only the headphone stage.

I had both the Parsifal Ovations and the Leonores with which to evaluate the new dac25.2 D/A converter/headphone amplifier from Roy "Music" Hall. (The man is now a brand.) I used the McIntosh MCD205 CD changer or the Denon DCD-1650AR CD player as a digital transport, with Analysis Plus Digital Oval S/PDIF interconnect. The integrated amp was the LFD. I also used Powered Advent speakers and Audio-Technica ATH-AD700 headphones.—Sam Tellig

I don't routinely measure the products written about by Stereophile's columnists—Sam Tellig, Michael Fremer, Art Dudley, Kalman Rubinson, John Marks—but when something comes along that catches their and my fancies, I do get it up on the test bench. Such was the case with the Chinese-made Music Hall dac25.2 D/A processor, which Sam Tellig wrote about in the August 2009 issue, as it offered a lot of both features and sound quality for just $599. It even uses a tube—a single 6922 dual-triode—to give it the required degree of audiophile coolness.
