Not at all RV. 90 % of my listening is in the shop to 4 old Mirage speakers, Adcom electronics, streamed from the main system. The speakers are put in the only location available for them which is way off axis and there is no listening position, background music only. The tone controls were used to give me a rough approximation of what I think I should be listening to. I have never measured the system, no need. The only attribute I cared about was volume and volume it has, to run over the din of machines, to be heard with hearing protection on.
As I have said before, Music and sound are two separate issues. You can love music and not give a hoot about sound quality. Conversely, I know audiophiles whose collection consist mostly of audiophile specials. I know one audiophile who does not even have one classical record, or one Ornette Coleman record, just audiophile specials of popular music. and he has a $150,000 system.
I am two completely separate personalities. The shop system is caked with dust. I vacuum it off once every blue moon. The main system is meticulously cared for. I have not adjusted the shop system in decades. The only control I've touched in decades is the volume and that includes the power switch. With the main system every single Hz is looked at and massaged, totally neurotic. The music lover in me will listen to anything, while the audiophile in me is hypercritical. Think about it. I study every stylus under high magnification before it ever touches a record. How neurotic is that?
