    Vivid's new flagship Giya G1 "Spirit" launch in Chicago 11 Feb. 2017

    I don't think this mode is due to the tweeter. As I write in the review, "There is a low-level mode evident at 9.6kHz, which I imagine is the upper-midrange unit's primary dome resonance after it has been suppressed by the crossover's steep low-pass filter..."...

    Stereophile and Magico

    I have been discussing a review of the S5 Mk.II with Magico and I have asked for a pair for review to be delivered at the beginning of August. John Atkinson Editor, Stereophile

    Stereophile and Magico

    No, but the YG does break into parts that are much easier to move around, as does the Wilson. And Wilson provides a wheeled dolly with a built-in scissor jack that can be inserted beneath the speaker, then raised to make it relatively easy to maneuver. Moving the one-piece Magico S7, at 300 lbs...

    Stereophile and Magico

    We are interested, of course, but it is complicated, not the least because the bulk of some Magico speakers makes the logistics of a review problematic. See the review Michael Fremer did of the Q5 for an example: http://www.stereophile.com/content/magico-q5-loudspeaker-measurements . Our neglect...

    Non-Conformist Speaker Bias?

    I loved the sound of the Salon2 and it also measured superbly well. Indeed. I have heard some great dems of the K2 9800 and we very positively reviewed the Synthesis 1400, which was designed by Greg Timbers, a few years back...

    Non-Conformist Speaker Bias?

    Why would that be a relevant question? Only around 50% of the products reviewed in Stereophile are from companies that advertise. We have reviewed many panel speakers and horns over the years, just not in recent years (other than Herb Reichert last year on a small Maggie). Our choice of what...

    YG Acoustics Carmel 2

    Stereophile's review samples of the Carmel 2 were returned to YG after the review and I recently spoke with Yoav about what I heard and measured. He confirmed that these samples do have this cabinet resonance and suspects that there was something wrong internally. (He hasn't yet had time to take...

    Measurement Thread: Measured Effect of Speaker Isolators

    It' s documented on the Stereophile website. Ethan refused to conform to our posting rules, specifically our request that industry posters include their affiliation. Doesn't mean that we don't still recommend his RealTraps products or that Ethan and I don't have a cordial relationship. On...

    Sam Telling (Tom Gillett) causing quite a stir for Stereophile

    True, except that in the case of Stereophile's internal finances and such matters as how much I pay the magazine's contributors, you don't have a clue. Good idea. But one that happened too late. I regret to inform you that you failed the audition to be Sam Tellig's replacement :-) John...

    Sam Telling (Tom Gillett) causing quite a stir for Stereophile

    With all due respect, Marc, that is not correct. You wrote "Writing for stereophile is no way to get rich. They have lost a lot of talent over the years and more recently because they pay dick...Many of the writers at Stereophile are independently wealthy or are well heeled maintain [their]...

    Sam Telling (Tom Gillett) causing quite a stir for Stereophile

    I see you describe yourself as a "Professional Audio Reviewer," Marc. The first rule of reviewing is to restrict yourself to what you actually know. In the case of Stereophile's payments to writers, to the best of my knowledge we pay considerably more than other publications/webzines, and no...

    Conclusive "Proof" that higher resolution audio sounds different

    And that is indeed significant. It had been widely proclaimed for the past 14 years that the files that have now been definitively distinguished by ear could not so distinguished under any circumstances. That they could not be distinguished "proved" that there was no audible advantage under any...

    Conclusive "Proof" that higher resolution audio sounds different

    This is exactly the testing described in the Meridian paper being presented at next month's AES Convention, plus the restriction of the tests to trained listeners. Looking back at your contributions to this thread, it looks as if your objection centers on the used of trained listeners in formal...

    Conclusive "Proof" that higher resolution audio sounds different

    Seems like Stereophile is still living rent-free in your consciousness, Mr. Krueger. :-) But seriously, that Stereophile performs sighted listening has no bearing on the issue at hand, which concerns significant flaws in the much-lauded blind tests "proving" the inaudibility of such things as...

    Conclusive "Proof" that higher resolution audio sounds different

    This is all eerily familiar. Back in the Usenet days, Arny Krueger posted criticisms of a blind test that had been published in Stereophile. When I queried him about statements he had made about the test that were factually incorrect, he responded that though he hadn't yet read the article...

    Conclusive "Proof" that higher resolution audio sounds different

    I agree. But your spectral analysis, Mr. Krueger, showed that the ultrasonic content of the "keys jangling" file didn't reach 0dBFS. So even the bus-powered DACs will not be driven into clipping with this file. But again not at levels approaching 0dBFS in the octave above 24kHz. This...

    Conclusive "Proof" that higher resolution audio sounds different

    That's correct. Arny Krueger is misrepresenting my measured data (in the context of this thread). I found with two bus-powered USB DAC/headphone amplifiers that they were driven into clipping with a pair of ultrasonic tones, each at -6dBFS so that the peak waveform was 0dBFS. But as such...

    Conclusive "Proof" that higher resolution audio sounds different

    You're missing the point. Just because a test is blind doesn't in itself mean that it is a valid test. If interfering variables haven't been accounted for -- see Recommendation ITU-R BS.1116-2 (06/2014) -- then it is a flawed test. Now you and others have argued that sighted listing is also...

    Conclusive "Proof" that higher resolution audio sounds different

    The Meridian Prime has an AC power supply. I next measured a Meridian Explorer D/A headphone amplifier ($299), which is powered from the 5V USB bus. You can see that with the 39+41kHz signal at 0dBFS (above), there are audio-band products visible as high as -50dBFS. However, the oscilloscope...

    Conclusive "Proof" that higher resolution audio sounds different

    Here are two spectral plots of the Meridian Prime D/A headphone amplifier decoding 96kHz-sampled data representing tones at 39kHz and 41kHz, each at -6dBFS, the combined waveform peaking at 0dBFS. One plot is restricted to the audioband; there is almost no 2kHz product visible, the left channel...

    Conclusive "Proof" that higher resolution audio sounds different

    At least Arny Krueger has now admitted, earlier in this thread that he was wrong to have publicly accused me 15 years ago as being an "ex-car mechanic with no formal education in audio engineering" (though his apology was somewhat ambiguously worded). Perhaps in another 15 years, Mr. Krueger...
