Totally Ridiculous....Auditions on YouTube!

No such thing as a YouTube demo. Common listening through you iPad or phone, you can not hear a difference. 

Listening on YouTube to determine actual sound quality of a piece of audio equipment is of course useless…… It’s similar to try to discern the overall quality of a high end car or camera or even a restaurant range ( I’m a chef / restaurateur).

You can get an idea of the looks & features & see if it’s something you might want to pursue but that’s it. There are simply too many potential points of degradation along the way. Unfortunately w/ fewer & fewer actual good quality stores to listen stuff in person, it makes it difficult. I think now the audio shows are a good alternative although the sound quality at them can be quite varied.

I am a cognitive psychologist and have done a great deal of research on consumers’ perceptions of products using a method based on simple similarity judgements between pairs of products. So, while it is fairly straightforward to determine whether two videos seem the same or not, the tricky bit is to know why any perceived differences seem different. Actual differences might be masked in a low-quality medium such as YouTube. However, determining whether a perceived difference is due to the product or the display technology is the tricky bit. In such cases you might want to run down to your local dealer and check it out for real.

At this point, I'm totally shocked that folks that would subscribe to this forum, and know a thing or two more about HiFi than the average bear, and the reproduction of quality sound,  would still defend this nonsense........

I don't get it, do use youtube for motorcycle exhaust demonstrations.
