Ever Bought an Audio Product that was Stupid Good for the Money?

I bought a used 5 shelf Symposium Isis Ultra Rack with TT shelf last December for $3,300. A real game changer that justified the cost vs performance of the entire system. http://www.vpiforum.com/viewtopic.php?f=7&t=8479
Two tweaks - A sapphire thrust pad and ceramic bearing, and a tonearm rewire with Nordost Valhalla 2. $195 and $150 respectively. They each brought super improvements and collectively pulled my VPI HW-19 MKIV TT out of the stone age.

Genesis Physics model 7s - about $75 new in 1984. Still have them, never refoamed. What a set of tweeters! (See Human Speakers)
Oppo DV-980H - $83 used including S&H in 2015. Got me into hires.
Shure V15 RS. Still sounds great with original HE or SAS styli.

B&W CDM1 SE, $300/pr less than a year ago, cherry finish, like new codition. I think the seller knew they were worth more but he didn't seem to care.

MFA ’Venusian’ 3 chassis octal tube based preamp. An un-labeled prototype, seemingly with a unique circuit.

The bottom box is a 40lb power supply. Chock full of NOS(ish) rare and expensive Octals, matched low noise quads of red base RCA on the phono amp, etc.

Procured for.....$108.37 on an eBay auction.

One can’t even buy a thing like that, let alone find it on eBay for that kind of money.

Of course, this was an accidental bargain, not something that anyone could have bought as a regular item.
