"best advice I can see on your audiophile journey is to try some stuff make sure there are returns or at the very least if you buy it used that you'll be able to flip it and sell it to someone else if it doesn't work for you so you're not risking a ton of money. "
With an unexpected divorce, followed by an unexpected retirement and a suddenly "fixed" income, I use the same methodology. The key is having the patience to put the time in to research and locate what you want. And to get it for a price that allows you to flip it if need be.That being said, if I am sure about something, I don't mind buying new.
