How do you know when a stereo sounds good?

I ask guys selling expensive audio tweaks. They must know best, right? 🤔

Sorry but i dont put anything in the mouth of people and suppose nothing...Being polite is my policy....

Try to stick ONLY  on argument...Anyway we are lucky to have an OP who knows some audio....I only make my experience known.... Thats all.... 

By the way my acoustic treatment an acoustic devices controls were made of discarded plumbers artefacts and other junk material.... Helmholtz was not bothered by price " tag" of his bottles being a scientist, me too, being not very loose with money..... Cost = peanuts...

I am living proof that you could do your own job without buying ANYTHING...

To be PRECISE...

I dont pretend that my actual audio system in my controlled room is BETTER than any audio system here on Agon...

NOT AT ALL....

I pretend ONLY and I KNOW that there is no comparison between my audio room BEFORE AND AFTER this  acoustically treated and controlled acoustic  implementation , even not  optimally designed, but with my own devices, instead of the costlier more efficient work of an acoustician; there is no comparison anyway between my audio system BEFORE and AFTER my acoustical embedded controls with Helmholtz method... NO comparison at all....

Mahgister,

I’d cough up a round trip ticket for your acoustic savvy, though will settle for enlightened posts ;-)

Cindyment,

Please advise on what magic fuses, over priced cable, & AC noise isolators you've tried in your system. 

@boxer12 this poser along with @mivmike  and @kuribo are a bunch of anti tweakers and I think they all are from that Facebook Audiophile Hate Group.

Total posers and clowns.
