Blind testing has itself been proven one of the best methods to confuse listeners perceptions. Have you considered the influence upon a signal arriving at your ears and the effect of cloth or whatever stretching over your face? Quote:

And no, I’m not going to list the gear I run. Last time I stupidly did so on a forum I had the lot burgled . There’s another side to all this. There are some absolute bargains to be had today for, for instance in budget speakers. Sadly only the dedicated audiopress get around to reporting on such items :- from Stereophile magazine. JBL Stage A170: $499.99/pair $$$ Measuring a little over 3' tall and a mere 7.5" wide, this slender floorstander uses a combination horn/waveguide for its 1" aluminum-dome tweeter. Below that are two 5.25" Polycellulose-cone mid-woofers, one crossed over at 2.8kHz and the other at 1.8kHz: The Stage A170 is a 2.5-way design. On the rear of its vinyl-clad cabinet are two reflex ports, and two pairs of loudspeaker connectors to facilitate biwiring. Key specs include a 6 ohm impedance and a sensitivity of 89dB. According to HR, the JBLs weren't at all fussy when it came to intricacies of setup and projected "an enormous, nicely detailed soundstage." On rock fare, and apart from slightly rounding-off leading-edge transients, the JBLs offered "relatively unrestricted" dynamics and allowed music to roll forward "with ridiculous ease." Writing from his test bench, JA confirmed the speaker's above-average sensitivity and praised the Stage A170's "excellent measured performance, especially considering its affordable price." Not let’s throw a nasty suggestion into the ring. How many of you out there know many of the digital appliances, such as your Mac or whatever you run, are feeding dirty radio frequency signals not only into the ether but back onto your mains supply? If your audio gear doesn’t have effective noise suppression built between its power supply and the mains and your system can reproduce those higher frequencies, - - - - ? ? ? ? But hey, all that’s just audiophile nonsense, isn’t it ? ? ? ? Last edited by Ayn Marx; 05-17-2022 at 06:09 AM. |

Imagine you have need of a Digital to Analog (DAC) unit somewhere in the signal chain of your stereo listening setup. Let's say you get to test three units - a cheap one at 20 bucks, a medium priced one at 100 and an expensive one at, say, 3000. A cognitive bias you could have is that the most expensive unit is the best sounding one. It seems a reasonable assumption, but may influence your listening experience even when it's not true. This is bad if you want the best sounding setup. However, you can avoid being influenced by this bias by having your friend set up a blind test. So you listen to the same bits of music three / nine / 30 / whatever separate times with one of those three units in the chain. What makes it blind is you don't know which one you're listening to. All you get to do is rank unit A, B and C in terms of preference. Your buddy knows which is which. If you did this, you might find you prefer one of the cheaper DACs over the most expensive. Not necessarily, obviously, but there are many good examples of this, but specially when the most expensive product is overpriced due to snake oilisms that just don't matter. Quote:

I don't consider ground lift buttons a scam. But let's take cable elevators instead. Some may claim that the static electricity in your carpets and the occasional mechanical prod a cable might experience will significantly decrease your audio listening experience and that you should spend stupid money buying rubberized elevators for your cables to lift them off the floor. In that case, they've pretty much made up a problem so that they can sell a solution. That would be a scam which is what I'm trying to target with this thread. My claim then is that if you blind tested many times with your cables either on the floor or elevated on rubber feet, the results would show that you're not able to tell the difference. Spending money on rubberized feet might, from a utilitarian point of view, have kept you from spending money on something that did matter and also make you worry about non-existing problems. It might've been better for your wallet and your happiness to spend your money elsewhere. If you're really into audio gear, perhaps you know a scam or two?

AC line conditioners come to mind as a scam. If your house wiring is old or your utility company has not grounded your electric correctly . That 9,000 line conditioner is going to filter any thing.
Also the You Tube Critic is another audio scam ! |

Expensive Cables: High-end audio cables can cost a fortune, and the claims of superior audio quality are often unsubstantiated. In most cases, reasonably priced cables perform just as well as their expensive counterparts. Spending excessively on cables is a common pitfall.
Audiophile Ethernet Cables: Some companies market Ethernet cables to audiophiles at exorbitant prices, claiming improved audio quality. In reality, a standard Ethernet cable is sufficient for streaming audio data, and there's no evidence that premium audio-specific Ethernet cables make any difference. Excessive DAC Spending: While a good Digital-to-Analog Converter (DAC) can make a difference in audio quality, there's a point of diminishing returns. Spending thousands on a DAC may not yield noticeable improvements over a reasonably priced, quality DAC. Audiophile Power Conditioners: High-end power conditioners are often marketed as enhancing audio quality by cleaning the power supply. In practice, they might have a minimal impact on sound quality, and their high prices may not be justified for the average consumer. Overpriced Accessories: Accessories like equipment racks, vibration isolation feet, and fancy power cords can be quite expensive. While they might have a place in some high-end setups, they often don't significantly improve audio quality for the average listener. Chasing High Sample Rates: Some audio enthusiasts believe higher sample rates (e.g., 192kHz or 384kHz) offer better audio quality. In reality, for most music playback, 44.1kHz or 48kHz sample rates are more than sufficient. High sample rates can lead to larger file sizes without a discernible improvement in sound. Excessive Speaker/Room Treatments: While acoustic treatments can improve sound quality in some cases, overinvesting in room treatments without properly analyzing your room's acoustics can lead to diminishing returns. Unsubstantiated Claims: Be cautious of products that make vague or unverified claims about sound quality improvements without providing concrete evidence or independent reviews. Buying Based on Brand: Some people spend more on audio equipment simply because of a well-known brand name. While brand reputation can be an indicator of quality, it's not a guarantee that you're getting the best value for your money. ebxya.com |
