There is one thing i like about Amir investigation...
It debunk the myth and magic marketing LINEAR link between S.Q. and price tag...There is none...
For example in dac... Dac is a mature technology, and we can now afford a very good one at relatively low price...
And in my acoustic experiments i discovered that improving acoustic is way more powerful than upgrading cables or dac or amplifier and sometimes even speakers...( if you have basic good one to begin with for sure)
By the way i am neither objectivist or subjectivist, no more than Gulliver was egg small ender or big ender...
Acoustic is key for me...But how can we criticize someone giving to us more information to digest ? I will not...
