Stand Loudspeaker Reviews

The match between amplifier and speaker for single-ended operation is critical, which is why John Atkinson suggested I let Wavelength's Gordon Rankin lead when it came to choosing a speaker to partner his special-edition Cardinal amplifiers. If you're not talking roughly 92dB sensitivity and a fairly benign load, say no lower than 6 ohms, you're just not talking single-ended. That precluded running the Cardinals on the big Avalon Ascents with their lowish 86dB sensitivity (in spite of the relatively benign impedance curve).

After more discussion it became evident that the best speakers to use were the very ones Gordon employed in his own reference system—the Swiss-made Reference 3A Royal Master Control loudspeakers.

Colleen Cardas strongly urged me to try the Callas loudspeaker from Opera Loudspeakers (whose products she also distributes in the US), which she claimed was an ideal match for the Unison S6 amplifier I reviewed last August. In my experience, the stand-mounted Callas ($5000/pair) is unique among loudspeakers in being the logical contrapositive (inverted and flipped, so to speak) of the usual D'Appolito driver array of midrange-tweeter-midrange (MTM).

When something called "high fidelity" assumed fad status during the 1950s, many manufacturers climbed on board by the simple expedient of adorning their last year's product with a high fidelity label. The Home Theater bandwagon is a little harder to jump on, because loudspeakers for use with television sets require something "ordinary" stereo speakers don't: magnetic shielding (or, more accurately, magnetic cancellation). Without it, placing the speakers within a few feet of a large-screen set does psychedelic-type things to the color (footnote 1). However, adding magnetic shielding, usually in the form of a second magnet glued to the rear of each loudspeaker's motor magnet, is the only thing that some loudspeaker manufacturers change before slapping a Home Theater label on last year's stereo speakers.

Late last year, when I first heard of the Music Hall Marimba, I was happily surprised: One of my favorite hi-fi manufacturers had finally introduced its first and (so far) only loudspeaker—and it was seriously affordable at $349/pair. I wanted to review the Marimbas right away, but grumpy old Sam Tellig beat me to them.

The Boston Acoustics A40 loudspeaker ($150/pair) has become "legendary" (ie, it's stayed around for a while), probably because a pair of them images as well as Rogers LS3/5As. Unfortunately, it is no match for the LS3/5A in terms of smooth midrange response. Of course, at $150/pair, it shouldn't be.

I was originally going to do a review comparing the Spectrum 108A ($200/pair) and the Boston Acoustics A40. On first listen, I was mightily impressed by the A40. But after Stereophile's Larry Archibald schlepped me out a pair of the 108As, I didn't much want to listen to the A40s.

Of all the speakers I've heard through the years, the $3000 ProAc Response 2 (footnote 1) is definitely one of my all-time faves. One of the few high-end speakers at any price that sounds equally at home pumping out Prong as it does Puccini, the Response 2 blew me away with its incredible musicality and just plain "rightness." The Response 2 doesn't call strict attention to any one area of technical achievement, like so many Audiophile-Approved jobs, but just makes music so naturally and unforcedly that I hesitate, even considering its remarkable performance, to call it an "audiophile" loudspeaker. Yah, I dig the Response 2! So last year when ProAc introduced the Studio 100, a new affordable version of the Response 2, I got excited.

Immedia introduced the German Audio Physic speakers at the 1994 Winter CES. As I mentioned in my Show report (Vol.17 No.4), I felt the price:performance ratios of the three models displayed was an indirect one: the least-expensive—the Step—sounded best. Since I'm always looking for products that offer great bang for the buck, I arranged to receive a pair of review samples.
