Do you belong more to souce first or to speakers first school of thought ?

I’ve evolved LOL. Came back into the hobby through the angle of folks repurposing vintage pro audio as inexpensive high current power. That lead to signal processing but I was driving sub par speakers.

Fast forward five years and I’m a speaker devotee luxuriating in the market trend toward big baffle mid fi heritage speakers and fast small subs :)

@hilde45 and others.  I appreciate your humor.  Let's not be REAL serious about this.  Most us us have a decent to awesome rig.  For those in that category, it is upgrading the weakest piece.

That's certainly true, generally speaking, but first it is not always easy to determine the weakest link, and then by changing any component your change the overall balance, so you might upgrade but not get better sound or improve some aspects of the sound and make others worse. This is a form of art, I would say.

In my case, I think I know that the weakest links are cartridge and speakers, though they are not weak links, so I have no need to upgrade, only a moderate wish.

There is theory and there is practicality. Linn's theory is correct, but to maximize your investment, you'd want a well matched system. There's no point in arguing for a $1000 front end and $100K speakers or vice versa. So much is based on the room.
