Ajax Posted June 13, 2020 Share Posted June 13, 2020 Hi Paul, Thanks for the effort you have put into this, I believe it is incredibly relevant to how we choose audio equipment. I'm really at a loss to understand why more audio enthusiasts don't recognise (or accept) the negative effect of bias and the need for DBT. Maybe it is just too hard and will spoil their fun but with 30 day return offers I'm not sure why audio clubs for example do not promote them at their regular get togethers. I would have thought manufactures would jump at the chance of having 20-30 of their target market listen to their gear. FYI they just completed a controlled test on the effect of aspirin on bowel cancer in Aus. They were so concerned about the placebo effect (as recipients had to be told what they were being tested for) that the randomised-controlled trial monitored 427 people that given aspirin and 434 people that were given a placebo, for between 10 to 20 years. All of them had Lynch syndrome, an inherited disorder which puts them at higher risk of a range of cancers, including bowel cancer. Of interest they found that two aspirins a day, for an average of 2½ years, reduced the rate of bowel cancer by about 50 per cent. https://www.smh.com.au/national/an-aspirin-a-day-helps-keep-bowel-cancer-away-study-finds-20200612-p5524r.html Anyway my point is that if medical scientists, who are testing for life and death cures, are so concerned about bias why aren't we? Why do audiophiles resist DBT so adamantly. Why do advertises pay celebrities exorbitant amounts of money to promote their products if they don't think they will influence our thinking? Apologies if off your specific topic, just wanted to say a very sincere thanks for your efforts. pkane2001 1 LOUNGE: Mac Mini - Audirvana - Devialet 200 - ATOHM GT1 Speakers OFFICE : Mac Mini - Audirvana - Benchmark DAC1HDR - ADAM A7 Active Monitors TRAVEL : MacBook Air - Dragonfly V1.2 DAC - Sennheiser HD 650 BEACH : iPhone 6 - HRT iStreamer DAC - Akimate Micro + powered speakers Link to comment

And I don't necessarily disagree with anything you said here (I'm open to hearing evidence for one way or the other). But I still would like to see some studies or properly conducted blind tests that demonstrate that longer term listening can be more sensitive than shorter-term, 8-10 seconds switching when evaluating minor differences. That's certainly not the way the industry conducts subjective listening tests, although I've not found a clear indication of whether it's because short-term switching is just easier to conduct and more convenient, or because echoic memory limits our ability to evaluate minor audio differences beyond a few seconds. In conversations with some audio testing professionals, they did indicate that shorter-term, quick-switching was the way to detect minor SQ differences. But, again, that's just someone saying it, and what I'm looking for is objective evidence for whether it's true or not. Hi Paul, Your intent in establishing this blog is honourable, and your patience while attempting to enlighten the naysayers such as Alex has been exemplary. Unfortunately the majority of people (not all) put their emotions and beliefs first and will often cherry pick or alter the facts to match them. Very few take a rational approach to a subject that has feelings associated with them. Just look at the rebound in the sharemarket, which assumes that the Pandemic will not affect the economy, despite the evidence that things are gong to get a lot worst before they get better. There is a book by physiologist Mark Manson "Everything if F*cked, a book about Hope" that explores why people adopt unhealthy beliefs and behave as they do despite the facts. https://www.amazon.com.au/Unti-Manson-2/dp/0062888439 I would also commend those looking for a more rational approach to audio reproduction to view Archimago's Musings' blog and the Audio Science Review website. I find they give a good balance to the more subjective views you find here.

Popular Post Ajax Posted June 29, 2020 Popular Post Share Posted June 29, 2020 Hi Paul, I'm not sure if my attitude is "so negative", however, I truly believe most people, whether they are audiophiles or whatever, allow their emotions to dictate their actions. That is why your thread is so welcome as bias MUST dictate how we perceive the world or a piece of audio equipment. To not acknowledge that we all influenced by what we are told to expect or what see as well as what we hear is full hardy. In my post above I stated "I would also commend those looking for a more rational approach to audio reproduction to view Archimago's Musings' blog and the Audio Science Review website. I find they give a good balance to the more subjective views you find here". This to me this is just common sense as there are no measurements published here just opinions. If you want a balanced view on a piece of gear you need both. It is why stereophile has always publish both the opinion of the reviewer and measurements. pkane2001 and Teresa 1 1 LOUNGE: Mac Mini - Audirvana - Devialet 200 - ATOHM GT1 Speakers OFFICE : Mac Mini - Audirvana - Benchmark DAC1HDR - ADAM A7 Active Monitors TRAVEL : MacBook Air - Dragonfly V1.2 DAC - Sennheiser HD 650 BEACH : iPhone 6 - HRT iStreamer DAC - Akimate Micro + powered speakers Link to comment
