Sidebar 2: Measurements
Logistical problems prevented measurement of the Vandersteen VCC-1 two-way center-channel loudspeaker. The Vandersteen 3A's sensitivity is a little lower than average at an estimated 85dB/W/m (B-weighted). A minimum amplifier power of 50Wpc would be a good idea. Its impedance remains below 6 ohms for much of the range, and dips under 3 ohms at 35Hz. The 3A is a moderately demanding load, though the phase angle is usefully low.

Other than a small suckout at just below 1kHz and some response ripples in the low treble, which would appear to be due to reflections…

Marking Their Territory?

It's easy for us audiophiles to feel neglected. Consider that this year witnesses the debuts of not one, but two new audio formats that should answer the prayers of just about every frustrated audiophile out there: SACD and DVD-Audio. Both approaches represent the state of the art of recording and reproducing music, and finally fulfill for serious listeners the promise that CD teased us with more than 15 years ago.

But this, the biggest news for music-lovers in years, has hit the mainstream press with a resounding 24-bit thud. In fact, the recent brouhaha of Napster vs Big Music and the…

Recording of June 2004: J.S. Bach: <I>The Well-Tempered Clavier, Book I</I>

J.S. BACH: The Well-Tempered Clavier, Book I
Till Fellner, piano
ECM 1853/54 (2 CDs). 2004. Manfred Eicher, prod.; Markus Heiland, eng. DDD. TT: 116:58
Performance *****
Sonics *****

To those who listen to Bach casually, this new recording of the Well-Tempered Clavier, by Till Fellner, is sheer pleasure—its legato line clean, graceful, and intelligently colored, its sound picture warm, clear, and inviting. But to those who follow Bach performance, the recording also signifies larger things—such as a triumphant culmination of the past 20 years of Bach on piano.

PSB Alpha B loudspeaker

Paul Barton is a legend in the speaker business. For 25 years this musician and engineer has dedicated his life to providing speaker purchasers with higher levels of sonic realism at lower prices. Barton is a frugal perfectionist, and his obsession with psychoacoustics is evident in all his designs. I was mightily impressed with his midpriced Image 4T (Stereophile, February 2001), which was, like all Barton designs, designed with the assistance of the facilities of Canada's National Research Council.

Although PSB makes more than two dozen speakers ranging from $199 to $2699/pair, it is…

In the upper-middle frequency range, the only instruments that at times lacked naturalness were the brass, particularly the trumpet. In a mellow jazz recording such as Miles Davis' Kind of Blue (LP, Columbia/Classic CS 8163, Quiex pressing), Davis' trumpet was not harsh, but seemed highlighted, as if the engineer had added another spot mike. On recordings with more energetic and highly modulated trumpet passages, such as Buena Vista Social Club (LP, Nonesuch/Classic RTH 79478), trumpet passages sounded, well, too brassy, detracting from the realism of this excellent recording.

Despite its modest price, the PSB Alpha B offers slightly greater than average sensitivity, at an estimated 88.5dB(B)/2.83V/m. In addition, its plot of impedance magnitude and phase (fig.1) suggests it is a fairly easy load for an amplifier to drive. Although the minimum magnitude is 3.9 ohms at 250Hz, the electrical phase angle at that frequency is very low.

Finite-Elemente Pagode Master Reference HD07 equipment rack

About once a week, I hear about some new audio accessory heralded by breathless claims of stunning performance gains that "you've got to hear for yourself." Most of these I ignore, and of those I do consider, nearly all wither when subjected to logical engineering analysis. Every so often, however, one of these wonder widgets finds its way into my system.

That's what happened with Finite-Elemente's equipment racks and component feet. The first time I heard the claims of sonic improvements, I didn't give them much thought, even when they were validated by the generally sane Allen Perkins…
