Is it possible to get Hi-end sound ??

Wrong hobby for the poor...but after all high end sound is a state of mind, a mental thing...I thought I had hi end sound before I discovered Audiogon, now 15 G's later I still don't have it, so that tells you something, lol...

It is possible to get sound that you can enjoy. But can you get sound that everyone else enjoys? no.
You have to know what sort of 'bad' in the sound you can accept, and what sorts are terrible to your ears. Then buy the not so great stuff that fails in the areas you do not care about. Let's say all you can afford is a $25.00 flea market receiver, and some 'white van' no name speakers, another $50. used, and a used CD changer, another $30. You could be in heaven. (or Hell, depending on your ATTITUDE.
((If you were the typical cheapskate audiophile, then you would extoll the virtues of your system, and denounce others whose choices differ. LOL!!))
I can hear the gnashing of teeth already.. from my fellow audiophile wannabes... (i am an Audiophile wannabe too, if that helps alleviate the pain.) All I need is another $150,000. to have a good system I could brag about.
As it is, plenty of folks would say my system is 'thin' no bloom.. (Who cares?, It has super clarity, tight! my thing!)

I wouldn't say that it's not a hobby for the poor. Not having the money doesn't put you at as big a risk. You do not have to spend 15 grand to enjoy what your ears hear. There's alot of lower cost components that would be stellar for someone who never had a good system. However, the hobby is an addiction and you should be very careful if you lack self control. You need to decide what you have to spend to get started. Then decide whether you want vintage or modern equipment. Don't get discouraged by what you read after asking your big question!
