Upgrading without ever learning about acoustics is very often deluding ourselves...
Billy is not a strawman it is an existing character... It is who i was before learning and experimenting ...
My name was Billy ...😊
He described me.😁 Are you saying that i was the only one Billy here?
Reading audio threads there is a crowd of Billy here who are like i was not so long ago ...
Many upgrade because they dont know what else to do to improve what they own already which is good but not enough when you read marketing stuff without reading about acoustics, and mechanical and electrical working dimensions controls which are the optimizations solutions not buying a costlier piece each time ...
Billy is a great rarity or doesn’t exist at all. A strawman to use for the sake of argument.
You can keep an eye on what’s going on in audio and do upgrades from time to time and still be very happy with the sound you have now. I think that audio is progressing and it makes sense to keep up with what’s new.
