Good-sounding audio components?

For me, reviews of all types, but mostly backed-up by recommendations by friends (including a few I hold in high regards here) and dealers (remote) I trust. Unfortunately, I don’t have many good HIFI dealers in my area except a couple good used dealers), and the one dealer who does carry very good stuff is very high end (albeit I got my used Vandersteen Treo’s from him that he took on trade), thus, I have had to purchase many of my components without listening and comparing.

It’s worked out well thus far, but I do a lot of reading, talking, and investigation now days.

You have to do your homework. 

All of the above.    It is an easy hobby to make big money mistakes on.  That's for sure.    I always try to listen to the product,  what ever it may be.  Thats's often difficult depending on where you live.

I always try to buy something that is low risk, 30 day trial, maybe used equipment that I can buy at a good price and there is minimal risk.

Avoid lateral moves.   If you really like something and its a bit out of your budget, save and buy that ,rather than something that is just ok

All of the above, and I would add try to audition a piece in your own system.  If there are still bricks and mortar stores in your area and they will allow for such a thing, then great, but I would also strongly reward them by giving them your business and not stiffing them by purchasing  for 5% cheaper on the Internet.  If that isn't possible, buy from a company that has a good return policy, and be prepared to pay a restocking fee.

actually....

i'm trying to un-become an audiophile, now.
