similar speakers

+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.

To hardcore audiophile (which I am not)...there are no similiarities between products...every piece of equipment is different...even the same model from different production run...we are talking people who encase turntables in concrete, stay home alone at dust their amps, measure speaker placement in mm...so a familiar section would be pointless imho
