Don't bother. Curl has nothing. He's been saying the same incorrect stuff for the last 40 years and is impervious to any actual data or evidence that gets in the way of commerce.
I just got an Audio Advisor paperback catalog in my mailbox a few days ago and I actually opened it up and looked at it for a couple of minutes. The first page I opened up to was a whole page on John Curl and the special power amplifiers he makes. The top “JC” model actually uses one or some of these Bybee Quantum things in them and sells the amp at a price far above $5000 (I think closer to $10,000). I almost said to myself I want to save up some money and buy one of his JC amp one day. If what you say is true, is really true then please reiterate this one more time to help a man (me) save 5 grand and get a Benchmark AH2B instead. Thank you.
(emphasis mine)These devices work on the quantum mechanical level to eliminate sub-audible noise—i.e., noise unmeasurable by typical test-bench instruments. The results are previously unattainable resolution and beauty in home audio and video. For more than twenty years Original Equipment Manufacturers (OEM) and customers have used Bybee Quantum Purifiers to enhance the performance of nearly every level of audio and video system.
Experienced audiophiles with knowledge of electronics and good soldering skills can improve the sound of their system components at very reasonable cost by installing Quantum Purifiers themselves. Loudspeaker upgrades are just as easy. These purifiers will require a break-in to sound best.
I don't think you need to wait for @SIY to reply; that product description says it all.
Hey, a 5 cent 25 or 30 milliohm resistor wrapped in bullshit is nothing to scoff at.
Indeed. @amirm even states that the thermal management issues probably mean these units frequently have hard lives. This one is clearly not of recent production based on the pictures and the one I just bought - like 3 days before the review - so may have quite some time on it.Back to the subject, four or five people here have said this unit is probably faulty. Can this be addressed?

Amirm always likes to evaluate some low-cost junk products. Why can't I evaluate HI-END products? Is it because of fear of offending the manufacturer?
His most expensive reviewed products are high 4-digits, if not 5-digits if I recall correctly.
Most of it is loaned by other owners to prevent any bias.
Perhaps a better question would be, why aren't HI-END products offering themselves to be evaluated. Also a better question would be the definition of HI-END. Because the last I checked, Benchmark AHB2 measures at a 113dB SINAD. Interesting if that is not HI-END enough.
That statement is false on its face. If you believe that, you obviously are not familiar with the list of audio hardware that Amir has measured. And the interesting part is that a fair number of expensive, so-called "high-end" audio products perform very poorly.Amirm always likes to evaluate some low-cost junk products.
Because using a sine wave test signal has no reference significance, the music is not a sine wave
This internet forum is most definitely about music-lovers sharing their thoughts on audio systems - regardless of price - that perform well, but without making claims that cannot be independently verified and confirmed. It is a challenge to find good value and performance in audio hardware at all price levels. Plus, ASR has a reputation for exposing B.S. in audio marketing and at so-called "audiophile" magazines and websites B.S. We are not about drooling over subjectively reviewed blingy audio hardware that performs poorly, or about polishing sensitive egos of audiophiles, hardware designers and manufacturers. But if they earn and deserve praise, they will get it.
