The digital noose of TOTAL control of every aspect of American life is tightening around every neck and the sheep go baaaah.
Stero 5 , you put your card in A'gons liitle file, somehow I think that hackers who can hack the CIA and Bank of America just might be able to do same to A'gon.
You have to be fool to put card on file anyplace on line.

+1 that this approach would be a waste of time, and potentially even misleading.

Without prejudice to any other arguments, simply posting a random, arbitrary or limited list of suggestions with an elusive target of actually getting "similar performance " kit is BS and blind luck at best, with a high probability that it won't work optimally with your kit.

System synergy matters .... Big time. Brand X cannot be simply randomly or blindly swapped for Brand Y because of the system synergy alchemy formed by ALL of the interaction of electronics, source, speakers and cables.

Putting credit card is not the worst error, but putting banking card on A'gon or even ebay/paypal file is definitely foolish and naive.
I use prepaid debit cards ONLY.

True , not worst but still foolish.

I'll still buy here, but won't sell anymore. There are just too many other sites for hobbyists.

It's not the money Audiogon charges, it's all the changes over the past few years. Too intrusive and restrictive, all the signing in over and over (what's up with that anyway?). If I hadn't started here back when it truly was just a bunch of audio-people trading stuff I might feel different. Remembering the good old days gets in the way for us old dudes.
