The SOTA Sapphire was the first, and the most successful in terms of sales, of the new generation of high-end American turntables. As such, the SOTA can be viewed as leading this country's resurge ence of interest in high-quality turntable production. At the time of the SOTA's introduction in 1981, it was the only high-end turntable manufactured in the US. Since then American-made turntables have appeared from the likes of AR, Mapleknoll, Sonographe, and VPI.
I am puzzled. No, really. I know you find it hard to believe that we sacerdotes of the golden-eared persuasion could ever be perplexed, but I have been pondering the imponderables of ports. Ever since the classic work of Richard Small and Neville Thiele in the early '70s showed how the low-frequency response of any box loudspeaker can be modeled as an electrical high-pass filter of some kind, with the relevant equations and data made available to all, there would seem to be very little reason why all loudspeakers with the same extension should not sound alike (or at least very similar) below 100Hz. Yet after reviewing 20 dynamic loudspeakers (and using 24) in the same room over the last seven months, I am led to the conclusion that speakers vary as much in the quality of their mid-to-upper bass as they do in any other region. A few are dry, more are exaggerated in this region; some are detailed and "fast," most are blurred, with the upper bass "slow" (by which I mean that the weight of bass tone seems to lag behind the leading edges of the sound).
High-quality, low-cost loudspeaker systems are not an everyday blessing. The Rogers LS3/5a has survived for more than a decade precisely because so few US manufacturers sought musical accuracy as distinguished from high output and powerful bass. The economics of loudspeaker manufacture also don't lend themselves to economy. The cost of woodwork is driving the price of speakers up almost as fast as the cost of sheet-metal work is escalating the price of electronics.
While brushing my teeth this morning, it occurred to me that there are significant similarities between a toothbrush and a tonearm/cartridge. The bristles would be analogous to the cartridge and the brush handle to the tonearm. In either case it is the business end of the device that does all the work. The bristles track the contours of your ivories in search of hazardous waste deposits, while the cartridge tracks the record groove transducing wall modulations into an electrical signal. I think that this is where the old adage came from: "A used cartridge is like a used toothbrushnobody wants one!"
Remember Rube Goldberg? He was a cartoonist during the late 1920s to early 1950s who specialized in devising the most outlandish and ingenious devices ever conceived by man, before or since. A Rube Goldberg mousetrap, for example, would occupy an entire small room. In taking the bait, the mouse would tip a balance beam, dropping a steel ball into a gutter, down which the ball would roll to strike a paddle whose spin would wind up a string that hoisted a weight into the air until it reached a trigger at the top, which would then release the weight to drop onto the unsuspecting mouse. Splat!
The latest edition of Audio's annual equipment directory lists 238 speaker manufacturers. At best I can claim to have heard one product from 10–15% of the manufacturers on this list, and the top of the current product line from a far smaller percentage.
There is something refreshingly no-nonsense about the design and construction of this turntable. It looks as if someone just said, Okay, this, that, and the other thing need to be done. Let's do it. And then they did it. In appearance at least, it is about as simple a design as you're likely to find. What sets it apart from other simple designs is that this one is built like a battleship! Everything is heavy-duty (notto mention heavy), from the 10-lb, lead-laminated aluminum platter to the ¼"steel-reinforced subchassis.
