Last September, in Vol.15 No.9, I started my quest for the Ultimate Kilobuck Tube Amp with reviews of the $995 Panor/Dynaco ST70-II and the $1695 Nobis Cantabile. While neither really fit the bill—the Dynaco fell a bit short in terms of sonics, while the Nobis was priced a bit higher than a thou—they got me thinking of the Ultimate Kilobuck Tube Preamp. Because the greatest amp in the world can only sound as good as whatever drives it, and there's no sense looking for a kick-ass affordable tube amp if you're going to play Scrooge McDuck when it comes to the preamplifier.
If Canada has emerged as a hotbed of loudspeaker production in the past few years, the folks at Audio Products International must be positively sizzling. Of their three lines—Mirage, Energy, and Sound Dynamics—Mirage is perhaps the best known in the US, with Energy running a distant second. Mirage, at least in their flagship M series, features rather esoteric bipolar designs, while Energy sticks to the more conservative, forward-radiating approach. Stereophile has had extensive exposure to the various Mirages (a review of one of the M-series babies, the M-7si, is scheduled for a future issue); our exposure to Energy has been virtually nil, save for the odd Hi-Fi Show and CES. And thereby hangs a tale.
Sonus Faber was founded in 1981 by Franco Serblin. Real wood has always featured strongly in the construction of this company's evolving range of costly, compact loudspeaker systems (footnote 1). The first was called the Parva, now in its FM4 form. This was followed by the Minima, a Tablette-sized model. The upmarket Electa came through in the last few years, followed by the Amator-Electa. This series increases in size and weight with each new introduction—for example, the Minima weighed 6kg, the Electa 12kg, the latest Extrema a massive 40kg or 88 lbs.
When I was visiting Santa Fe last Easter (footnote 1), one of the subjects I raised with JA was Naim's ARO tonearm. This unique unipivot design has languished in Class K of Stereophile's "Recommended Components" listing for far too long. JA explained that the regular reviewers have quite enough to do, thank you, just keeping up with speakers, electronics, and especially digital. The esteemed Martin Colloms is happily using an ARO on his Linn Sondek, and wrote a review for the English magazine Hi-Fi News & Record Review in May 1991, but since there is a very small but nevertheless vociferous overlap in US readership between the two magazines, it is Stereophile policy not to have two reviews by the same reviewer of a given piece of gear.
In recent years, computer modeling, finite-element analysis, and laser interferometry have brought about a huge increase in our knowledge about what makes the moving-coil loudspeaker drive-unit work. Nevertheless, it has remained fundamentally unchanged since it was invented by Rice and Kellogg more than 60 years ago. That doesn't mean that it hasn't been refined considerably; in this review I examine the performance of a design whose drive-unit technology has been taken to the limit of what is currently possible, the B&W Silver Signature.
If you read Stereophile regularly, you already know that all audio equipment does not sound the same. But did you know that a given piece of gear can sound better or worse depending upon how it's set up and used? With a few simple tweaks, you can bring out the best in your audio system.
Choosing a loudspeaker can be difficult. Although it is easy to be seduced by a certain model's special qualities, that exceptional performance in one area is often at the expense of other important characteristics. Go with high-quality minimonitors for their spectacular soundstaging, but give up bass, dynamics, and the feeling of power that only a large, full-range system can provide. If you choose an electrostatic for its delicious midrange transparency, you may have to forgo dynamics, impact, and the ability to play loudly. Pick a full-range dynamic system for its bass and dynamics, but lose that edge of palpability and realism heard from ribbon transducers.
Several issues back, we reviewed rather enthusiastically a pre-production prototype of this preamp. The original was an unprepossessing-looking device on two chassis, interconnected by a 3' umbilical, with a squat little preamp box and an even squatter power supply with humongous cans sticking out the top. We averred that it sounded nice. The production model is so nicely styled and functionally smooth that we wondered if it might not be another Japanese product. 'T'ain't.
