If you auditioned 30 amps on various systems or speakers then you didn't audition anything.
Just seems like a manic post. I glanced at it, but it's too much to even begin the effort of trying to make sense of or to place his post in any meaningful context.
The purpose of the post was to engage with others who may have had questions and or exchange experiences. Again take a reading lesson, I have owned over a 3rd of the amps listed and have had unlimited access to the others on the list shared by a small but choice group of audiophiles friends who actually enjoy the hobby and thought it would be helpful to others. We for the most enjoy what we do and share our evaluation experiences and our quite happy to answer unbiased questions as it relates to them.
Cheers
