Audio deals you bought that seem impossible for the price?

I knew I could not afford the stereo equipment I wanted and in fact the class A amplifier I wanted is in my opinion one of best ever manufactured. I was wanting, looking for a Krell ksa300s which was last made in 2010. The Amplifier weighs in at almost exactly 185lbs not as big as you would think but, there is one reason for its extreme weight. Almost any wire that you think would exist within the chassis was replaced by oxygen free copper bars and has a massive toroidal power transformer. The extreme use of these copper bars insures that frequency signals shoot straight through internal circuitry much the same as you get from the use of expensive high end component and speaker cables. Thing looks pretty bad with 4 electrolytic capacitors as big as automotive oil filters. I've pretty much just reworded an article online from Stereophile so, if anyone is interested in specs, test results just go online and enter ksa300s and you will almost get directly taken to two different detailed articles from Stereophile. I thought I would find it on eBay which I did and had been recapped little less than 3 years earlier and came also with a matching Krc-3 preamplifier and an excellant kas250cd/2 I paid $8200 and according to former owner a company from California offers a clone copy of the class A amplifier at only $25,000.
