I thought the original selling price of $4K was quite high. But $7K?, we're talking big bucks here! I didnt check the auction bidding results, but it wouldnt surprise me if the buyer was determined to have it, and perhaps placed a hidden snipe-bid. In other words, if someone else had bid higher, the guy who won mightve paid even more for it, maybe even $10K.
I wouldnt mind owning a G33K, but way outta my price range

However, I dont think it can surpass the BA-5000, my #1 favorite Sansui amplifier.
