With great fear, I submitted to a full ear/nose/throat workup, part of which was a test of my hearing by an audiologist. I sat in a soundproof booth wearing a pair of ancient Koss Stereophones, indicating with a wave of my hand when I heard a sound. With an inferred pat on the back, the audiologist told me that my hearing was normal and advised that I take sinus meds as needed.
But a glance at the…
Editor: I find Michael Fremer's Review of Harmonic Technology Interconnects to be a quintessential example of a significant dysfunction in the audio press, or at least in Stereophile.
Unless I missed something along the way, a widely accepted criteria for electronic audio equipment is to add nothing to the audio signal except gain or transmit signal without altering it. This product, however, adds a great deal according to your own measurements, so much so that it might better be described as a signal "enhancing" processing device. Mr. Fremer finds the…
Editor: As a publisher myself, a number of thoughts occurred to me after Michael Fremer's review of the Cyberlight interconnects in the August issue.
This is not the first time there has been a remarkable difference between Mr. Frember's observations and JA's measurements. I recall a similar situation when Mr. Fremer also gave a rave review to a KR amplifier, which was found to be practically defective when measured. You ran the review at that time along with your measurements. As before, Mr. Fremer gave unconditional rave and recommendation to a product…
Editor: I was not surprised that Mr. Fremer expressed a strong preference for some "interconnects" that almost surely have audible linear and nonlinear distortions. Any dyed in the wool vinylphile clearly prefers music playback containing audible distortions. The same can be said of those who wax poetic about SET amplifiers.
There have been many instances of equipment reviews in your magazine wherein the equipment measured poorly but got a rave review. This just goes to show that listener preference (even a highly skilled professional listener) and high…
Editor: I had to rub my eyes. There it was, in glorious print, "I really don't see how the Cyberlight P2A and wave cables can be recommended. I am puzzled that Harmonic Technology, which makes good sounding, reasonably priced conventional cables, would risk their reputation with something as technically flawed as the Cyberlight."
Finally, a review with some backbone and truth!!! Or should I say, a reviewer with some backbone and truth. Well done, JA.
Now lets turn our attention to Michael Fremer. I give him high marks for integrity and standing on…
The Coltrane is the company's "statement" product, and at $50,000/pair, you expect more than a short riff improvised on a familiar theme. Olofsson…

There's a brassy-sounding big-band album by Ella Fitzgerald, arranged and conducted by Bill Doggett, called Rhythm Is My Business (LP, Verve V6-4056)—a great title, and a perfect description of one of the Mårten Coltrane's strongest suits. Get it…

I measured the Mårten Design Coltrane with the speaker biwired with the supplied Jorma cables and supported by the Black Diamond Racing cones and pucks, to allow its reflex port to be raised sufficiently high above the floor. Because of the speaker's bulk, it was not possible to raise it several feet from the floor for the acoustic measurements, as is my normal practice. I therefore had to window the time-domain data more aggressively than usual, to eliminate the effect of a strong floor reflection. This reduces the resolution of the farfield measurements in the…
