Friends, posting this video so all can benefit. Very informative, myth busting, comprehensive one hour video. Most of subjects are covered. power cords, interconnects, room acoustics. A must if you love this hobby.
YouTube - Audio Myths Workshop

Here is things that might interest you with time mentioned of the video (Copy pasted from other site) articles in bold are which I find interesting...:)

Starting Time/Topic:
0:00 - Introduction by Ethan Winer
1:06 - James "JJ" Johnston on the human perceptual system (auditory) and auditory testing
5:20 - Poppy Crum on how "we are programmed to hear speech and programmed to make expectations about what sounds should be"; includes example of "Stairway to Heaven" played backwards
9:40 - Ethan Winer on human auditory memory and a review of a variety of placebo tweaks like ac power cords, LP Demagnetizer, "Brilliant Pebbles," "Quantum Clip" etc.
Part 2: Ethan Winer video presentation
16:50 - Comb filtering and how it may be one explanation for many so-called sound differences reported by audiophiles from "placebo" tweaks
19:00 - Loudspeaker distortion and variations in bass response in most listening environments are much worse than those produced by electronic gear
20:15 - Specifications and anti-science bias by those who believe they don't matter
21:35 - The four audio parameters that define everything needed to assess high-quality audio reproduction (frequency response, distortion, noise, and time-based errors)
22:48 - Euphonic distortion
23:13 - Specs provide all that's needed to assess transparency as long as complete data is presented
24:09 - Masking Effect and artifact audibility
25:20 - Proper listening test methods

This is amazing!
It conclusively talks about things that I have long suspected but could never ratify in my arguments, as people need valid proof!

with industry leaders of such stature talking it should put all arguments to rest.

i especially liked the bit about power cords and the doo dads...

thanks for posting this hiten!
 
Yes. As audio is massively subjective thing at least one should respect and believe scientists/amplifier designers/professionals for basic fundamental things than move towards subjective audio listening debates. Which you know can be interesting as well :) ;)

Ethan Winer certainly busted a few myths for me. He was one of my starting points in what I consider a more realistic appreciation of audio and hifi.
 
Read a few initial chapters. There is a good discussion of various filters especially comb filter. The overall presentation of the book is not very involving but good amount of information. I have not yet come across any myth busters till now in the book.

Looking forward to completing the book during this weekend.
 
I wouldn't like to put off any prospective buyers (the guy has to make a living!) but he is quite prolific on the net and I wonder if there can be much in the book that is new. Anyway, books are nice, they look good on the shelf and can be read in power cuts :D

From memory, there was one audio myths article that he wrote. He focussed on pro audio, but later rewrote the article with stuff refocussed on domestic hifi. Will look for links...

Ot maybe the video was the first, and the article followed. Here it is, and maybe he invented the word Audiophoolery. On the other hand, maybe it was just the first place that I heard it.

Ethan Winer Internet reading: Links to various articles.

USD 39.60 without any discounts. There are cheaper options available though ;)


Update on the book - Almost at the end of the book now. Most of the chapters are related to recording rather than playback but the information is quite useful. Last few chapters are again about playback equipment and room acoustics.
Lot of listening tests are also there to understand some basic concepts.
 
Purchase the Audiolab 6000A Integrated Amplifier at a special offer price.
