I do need to add this for Clarity, each part in the audio chain overwrites the next until the Power Amplifier does its job.
There are simply (when listening), 2 types of power amplifier.
1. The Line Value Amplifier which is incapable of altering the data supplied from the previous piece of equipment and so listening tests are born along with Constant device change.
2. Large Current Power Amplifiers these are the boys who "hatch" the sound quality and provide detail and timing unheard otherwise, such as the Jungson JA-100, the Czech KR, not so much the Krell of old. With these there is no discussion available as the music reigns.
I spent my whole hobby time from the age of 13 until 58 before I discovered this.
The only other thing is that Power Cables set U free, Speaker Cables Constrict and Signal Cables are Constants.
Oh and Tables, plinths, platforms and Isolators are there strictly to deal with transformer oscillation and nothing else.
That is all of Hi-Fi and it's mystery.
I am available for lunch.
