When Hong Kong–based music lover and electronics-equipment distributor Klaus Heymann (footnote 1), now 70, first began organizing classical-music concerts as a way to boost sales, he had no idea he would end up founding the world's leading classical-music label. But after starting a record-label import business and meeting his future wife, leading violinist Takako Nishizaki, the German-born entrepreneur sought a way to promote her artistry. First he founded the HK label, which specialized in Chinese symphonic music (including Nishizaki's recording of Butterfly Lovers, the famous violin…
JVS: Let's talk about sound quality. I am finally posting clips from my whistling CD to my website, and spent some time listening to the sound. Even through my old, poor powered computer speakers, I could easily hear the difference between WAV files, MP3 at 320kbps, and MP3 at 192kbps. The smaller files really truncate my sound, rendering it much thinner, brighter, and lacking in overtones. If people are downloading clips that are less than 192kbps, they're hearing only a fraction of what was initially recorded. Have you considered posting lossless files and streaming at higher rates?

I first saw the Shure SE530 at the 2006 Consumer Electronics Show, when it was dubbed the E500. The '500 shared the current product's three-armature driver technology and in-ear, sound-isolating, sleeve fitting scheme, but that early prototype seemed almost crude in comparison with the SE530.
During the year or so it took Shure to bring the SE530 to market, it went through some changes, including its model designation. Shure added modular cables (different lengths are available), as well as a standard in-line volume attenuator and a Push To Hear (PTH) module ($50) that "allows you to…

Sidebar 3: Measurements
As I've written before, I have no means of assessing the frequency response of headphones—Keith Howard wrote an excellent article on this subject in the October 2007 issue of the British magazine Hi-Fi News—but I did measure the electrical impedance of the Shure SE530s with the headphones inserted in my ears. The measurements will thus include the acoustic loading of my ear canals, which I assume is not too different from the typical Stereophile reader's (though yes, the diameter of my "jumbo" ear canals is larger than average). The result is shown in fig.1. The…

Sidebar 2: Review context
The Snell Type K/IIs replaced the Hales System Two Signatures in my reference system, and were auditioned on the excellent Celestion 24" spiked and lead-shot–filled stands. Each pair was driven by the VTL 225W Deluxe monoblocks, Krell KSA-250, and Threshold S/550e (the last two reviewed elsewhere in this issue) via 10" runs of AudioQuest Green Hyperlitz. The analog front end consisted of a Well-Tempered turntable, just refitted with a Lary Pederson–modified Well-Tempered Arm, and a Sumiko Boron cartridge. The moving-coil's low output was stepped up with the…

Driving the loudspeaker with a variable-frequency sinewave oscillator revealed a lively cabinet, the enclosure vibrating significantly. Many resonances were detected, the most severe of them at 100Hz and 270Hz, which produced audible cabinet contributions to the tone. Rapping the enclosure with my knuckles produced a fairly lively tone.
Looking at fig.1, the Type K/II's impedance magnitude (solid line) and phase angle (dotted line), the sealed-box tuning is evident from the single impedance peak which reaches 24.3 ohms at 63Hz. The impedance never drops…
"Sam, HELP!!!! Wife wants stereo out of the living room, converting spare bedroom for my stuff."
It was a frantic fax from Houston.
Sorry to say, I'm unable to answer most letters or faxes because I don't have the time. But this one intrigued me.
"My current speakers," the fax continued, "appear to be too large for the bedroom. Any ideas on what to audition?"
I shot back—
"This is great news, Houston! With a smaller room, you can go for quality instead of quantity. Think small!!! Smaller speakers, smaller amplifier. Aside from the bass, you may get better…
