Quite a dialog we've got going here, eh? But pertinent, I think, to my high regard for the Studio 2s—the degree to which I received musical meaning, emotional response, and aesthetic reaction is directly attributable to the strengths of these speakers. No, I'll go further: that is the strength of these…

Although the Studio 2's sensitivity is nowhere near the specified 89dB/W/m—I estimated it at 84.5dB/W/m, B-weighted—it's still quite high for such a small loudspeaker. Coupled with a highish impedance magnitude, which only drops below 6 ohms in the lower midrange (fig.1), the Studio 2 will give the partnering amplifier an easy time. The low-frequency trough in the traces in fig.1 reveals that the port is tuned to 65Hz. A slight wrinkle in the magnitude trace at 320Hz is probably due to a cabinet resonance.

The Yamamoto A-08's two channels differed significantly in their voltage gains. Into 8 ohms at 1kHz, the right channel measured 19.85dB, the left 17.04dB. The circuit is mounted underneath the smart-looking wooden chassis. The review sample was missing the protective bottom plate; perhaps something had become misadjusted. The two channels also differed slightly when it came to output impedance. The right channel measured 3.2 ohms at 20Hz, dropping to 2.85 ohms at 1kHz and 2.16 ohms at 20kHz. The corresponding figures for the right channel were a little lower, at 3…
As far as cartridges are concerned, I doubt you can beat the high resolution, delicacy, and transparency of today's best low-output moving-coil designs, despite their high prices (as well as those of suitably hi-rez,…
