WHY DO PEOPLE FEEL THE NEED TO COMMENT ON CABLES AND EQUIPMENT THEY HAVE NEVER HEARD?

I totally understand. It depends on your preferences and situation design and science matters but sound matters the most.  My music brings me joy and piece. Yes I have an expensive system but I enjoy it. Some people like cars. I love audio 

but, others might reasonably disagree and think that minor details, such as the price, matter and that certain price levels cannot be justified no matter the sonic result.

Yes I have an expensive system but I enjoy it.

I don't see why anyone needs an "expensive" system to be able to enjoy their system? How is this relevant to enjoyment? Can you buy it?

Look I been doing this audio thing for 20 years. I have heard some really good gear. I have heard some well built, good sounding gear. I have heard really good reasonable and expensive priced type gear.  For some people a system that is under 1,000 or 10,000  Will do just fine depending on the components and their tastes and what gear they have actually had a chance to hear. Do I need an expensive system to enjoy it? NO! But chances are the gear that I tend to like will usually cost more because of what I’m used to and the sound preferences I have.  To each his own we all have different paths to get where we sonically wanna be.  I think it’s important to hear gear at all levels and price points  to get an idea on what’s possible 

“Expensive” is a relative concept. Items that you may personally consider to be expensive may be relatively “inexpensive” to others.
