Interesting discussion!
I fully understand acoustics
i fully understand tubes , SS, HD ,IMD, etc
i fully understand the human auditory system
I fully understand loudness and dynamic range of the normal and the
impaired auditory system -
have used a vast array of very costly to inexpensive
audio gear
after 50 years of changing gear I realize that if the recording is excellent so will the
listening experience!
currently I'm using a system that is excellent and cost a mere fraction of those setups of the past!
changing components is a PIA since there are no audio salons nearby! That leaves me to the prey of the reviewer, non of which are useful, the internet, and FedEx!
I find it a horrible process to buy, try and return!
I've lost interest in this hobby since the human interactions are gone, listening rooms are gone and again , the trial and error of choosing equipment is not appreciated.
It was fun!
