I measured the PrimaLuna DiaLogue Three using the Audio Precision SYS2722 system (see www.ap.com and the January 2008 "As We See It"), as well as my vintage Audio Precision System One. The maximum gain at 1kHz into 100k ohms was lower than the specified 12dB, at 9.67dB in the left channel and 9.9dB in the right. The preamp preserved absolute polarity (ie, was non-inverting), and the input impedance was very high, at >150k ohms at all frequencies. (I can't be more precise because the voltage-drop method that I use to measure input impedance becomes increasingly…
All of that is old news for some readers. For the rest, Soulution is the unlikely offshoot of Spemot, a 56-year-old company based in Dulliken, Switzerland, that manufactures specialty electric motors for the automotive industry (BMW, Volkswagen) and for…
But superb measurements don't always yield superb sound. Amplifiers designed to produce vanishingly low distortion can sound cold and uninvolving. That's how I felt about the Halcros. There was no there there.
While the Soulution 710's sound won't appeal to everyone, as demonstrated by the reaction of a few visitors here, it will appeal to anyone who values unparalleled transparency, startling transient cleanness, and a level of overall refinement that easily surpassed that of any other amplifier I have heard. The 710 gripped my Wilson Audio MAXX 3…

To measure the Soulution 710, I used Stereophile's loan sample of the top-of-the-line Audio Precision SYS2722 system (see the January 2008 "As We See It" and www.ap.com). I ran the 710 at one-third power into 8 ohms for an hour, which maximally stresses a class-A/B amplifier's heatsinking. At the end of this preconditioning period the amplifier's top panel was only slightly warm, at 90°F (32.2°C).
The voltage gain into 8 ohms was 25.9dB from both the balanced and unbalanced inputs, and both inputs preserved absolute polarity (ie, were non-inverting). The…
