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.  

Stoped into a resale shop one day and spotted a marantz 9-1 av receiver (new is $2100). The owner happened to be out this day and a nice lady was filling in. There was no price on it and the power cord was missing. I asked how much and  that no power cord concerned me as I could not even test if it would power up. She tried to call the owner but could not reach him. Right next to the marantz was a rca unit with built in turn table that was marked $90. She said they look alike so how about $90? I said no cord how about $80 and it was mine. Ordered new power cord and it has worked flawless for over three years now.

Flash sale at Crutchfield for the CS9080 center for $611. Pay $1 now and the rest when the item ships 5 weeks from now. I look around after paying…still $1,199 at B&H and locally. Next day, the rest of the charge hits my card. I had planned to use a different card and/or make the money to pay for it in 5 steady work weeks or cancel. Nope! Took the money out my checking account already and I called to see what gives. Seems they received the shipment just 5 weeks earlier and that’s why I was charged. Oh, well! Got the speaker and no worries about how to pay for it. It was done and over and on the way! Cool enough! 

The little Andrew Jones designed Pioneer speaker, which you can buy for next to nothing.

I bought a Vincent SA31 pre amplifier at half price in a sale, never had Vincent before but needed a cheap pre amp. It was originally around AUD$1000 got it for AUD$550, great bargain. Got it home fired it up and noticed it was a little different to the box so thought maybe minor upgrade and whilst box said SA31 the unit had SA31MK on it so I thought mk1 vs mk2. Had in system for a week before I queried with the store (after visiting Vincent website), the young salesman was apologetic but maybe I could just keep what I had as they had now stopped selling Vincent? So a new SA31MK rep AUD$1900 for $550.
