John Marks February 2016 Part 1:
"I was thrilled when Eric Feidner (Steinway & Sons' SVP for Music, Technology and Media; and, Executive Producer of Steinway & Sons Recordings), asked me to specify desktop/computer-audio systems for him, and for Mike Sweeney, Steinway's President." (continues in part 2)

John Marks February 2016 Part 2:
"Parasound's Zamp v.3 is hardly a newcomer, but, it's very feisty! I was really taken by its sound quality and its ability to drive loudspeakers of lower efficiency. And it is a stellar bargain, given the exceptional value proposition Parasound's Zamp v.3 represents."

The SkyFi Testing Process for Solid State Amplifiers:

We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage.

We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally, we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If everything reads clean, we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier then remains powered on to "burn in" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will be also be tested.

Final testing involves pushing actual music thorough the amplifier. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage KEF speakers that we're very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice.
