Two questions to make you mad.

Reading this is like following a wild pig trail, except it’s in a video game and the scenes occasionally repeat. 
 

Those are direct instruments , in guitars or amps I have used better capacitors, wiring and tubes and better cabling connectors to enhance the fidelity of the Amps , guitar and this to for sure applies to loudspeakers the Xover is a very important component , these speakers extra voice fine as a direct monitor 

but not even close to a full range Loudspeaker ,it has its place in a specific area .

The main lie by omission in audio is that we ( the industry and consumers) for OUR convenience forgot to say even to ourselves that the acoustic and psycho-acoustic knowledge value exceed the gear pricing....

Then going after cables or pointing to the difference between live event versus recording one , is missing the main point ...And this mislead people putting them in two groups : subjectivist and objectivist, the two groups focussing on the gear / measuring tools components instead of the psycho-acoustic event which need to be controlled ...

Anyway all these old quarrels  in audio will soon disapear in a psycho-acoustic revolution  which is already here...

Thankfully my Pella windows rarely allow the neighborhood players to be heard from inside the house. 

I’ve had a fun and way to long argument with a friend of mine that works in a vintage guitar store in LA, he knows practically every guitar player and their set up tout there. I would always tell him why do you sell all these beautiful guitars and then have them run through a Vox, Martin, or some other amp with full range speakers why don’t you get a high quality audiophile amp and a Hifi speaker to bring fidelity to the outrageously expensive guitar you sold them, he always says because that’s not rock n roll. 

I honestly don’t know why you can tell a live guitar a mile away playing through any old amp. I have a Steinway and Sons Spirio/r piano that plays back exactly the way the original player played it, this is the only Hifi playback I have ever heard in 40 years of recording.
