Buying used or sight unseen speakers a bad idea?

There is a member dispute link on the member page. One more thing. If you want to have recourse for your transaction you need to use paypal. They will block the funds in the sellers account the moment you raise a dispute until the issue is reolved. You pay 3%, but it is a from of insurance.

Another quick note: try to buy brands that are sold in local dealerships near you. That way you have access to repair techs that are in your area. You are also able to audition their products, then go out and find them used. When my Rotel amp starting blowing rail fuses, I took it to ListenUp here in Denver. They are a Rotel dealer, and the front desk guy was a little reluctant, but they have repair facilities onsite, and took good care of me. My Halo Pre can be supported by Gold Sound, a brick and mortar shop that's been in business for 20 years. Otherwise if something breaks, you have to ship it off to some out-of-town joint.
I do not recommend buying speakers unless you've listened to them first...

Realremo, the only problem I have with your post is that I am uncomfortable auditioning equipment at a "bricks and mortar" retail audio store because I would be taking up the time of a salesman who probably earns his/her living (in whole or part) through commission. Hence, if I take up the salesperson's time with the intent that I will buy used off A'gon or where-ever, any time spent with me would be time not spent with someone else who might be a serious buyer. But that's me.

As a newb I've bought on Audiogon once; A KEF center channel from another newb that didnt even leave me a feedback. Great.
I'm currently looking for a nice set of "classic" speakers because I feel they will hold their value over the HOT IEM of today.
I have bought a Kuro reciever from a sponsor;
Are they supposed to leave feedback as well ?

If buying "sight unseen" from anonmymous sellers was generally causing a lot of trouble this would be reflected in far more negative feedback than what is actually there(and the demise of audiogon). Typically, feedback is overwhelmingly positive, indicating problems are the rare exception and smooth transactions are the rule.
