Didn't pan out... When I went back to get them, I took a closer look and they were not as "Mint" as I/he thought. A few nicks and scratches here and there, front corner issue with one of the speakers, and half of the top of one speaker having discoloration (sun fading mark). I would have rated the condition of the cabinets a 90 out of 100. More importantly, the owner did say without a doubt that they need the "caps" replaced. Apparently he is an audiophile with a lot of Klipsch friends (started naming off all of the Klipsch classics that he and his friends own), perhaps some are members of the KAC. He was adamant that they needed "Crites upgrades" (I think I read up on that somewhere). I ended up offering him $400, explaining that with the condition and needing upgrades it seemed like a reasonable offer, but he would not budge. He said he needed to get $500 for them. I respectfully asked him to meet me in the middle at $450, which I thought was generous of me, but he declined.
Now, did I have buyers remorse before the purchase? I think not, but when you're standing in a million dollar home overlooking an equally beautiful lakefront view and the guy wants top dollar and won't budge, the street-wise kid in me kicks in and I can get stubborn too. Frankly, I think he will sit on them. They have been up for sale since November, so I don't think I'm the first to make him an offer. In his mind he was originally asking $800, then dropped the price to $500.
Thus the search continues... Thanks again for the information, it was a big help.
