Audio deals you bought that seem impossible for the price?

And I'm more of a "sounds good" guy. But you have to go with what you think works for you. Even if it doesn't, you will never know. Until you hear my Moabs.

@millercarbon agree whole heartedly re: the Raven Blackhawk Mk3.1. 
One recent unbelievable purchase was a pair of Sony SSCS5 standmount speakers. I bought these on Amazon for $73! Yes. $73. Now they don’t sound like $73 speakers. Before I got my Magico A3s. I had a variety of stand mount speakers. These are at least as good as all of them and they cost hundreds to thousands of $ per pair.  I have these a paired up with my pair of REL T/9i subs. The combo is tremendous. I don’t know how this can be. It confuses me. Essentially they are almost free. I have more $ in John Darko Amazon door stops and hockey pucks than these Sony’s cost. I bought them just for the hell of it. I thought maybe I would modify them with the GR Research kit. I decided against it. They sound so good as is and the value proposition is off the charts. 
The last one is the Intel NUC10 i7 that I built over specd for my Roon Core and mounted in a fanless case. The SQ is at least as good as my old InnuOS Zenith Mk3 and PhoenixUSB which I have since sold. Plus Roon Remote runs so much better and doesn’t crash like it used to with the Innuos gear. It also doesn’t flinch in doing DSP. All this at a total cost of around $800-900 as opposed to the thousands the Innuos gear cost. Another bargain.
