Alright, I have a good one for this thread. 7 years ago, I got back into my huge vinyl collection (I’m an Old). I decided to spend nontrivial $$ on a decent phono preamp, so I found a Graham Slee “Gran Amp 2 SE” on Audiogon for $275. Bought that, and then I bought a $200 power supply to go with it (because we all buy stuff for our stuff, right?).
Well, last week I saw a review on YouTube that said that the Gran Amp 2 was crap, and what a I really needed was the $129 Shiit Mani preamp! So I ordered that Shiit and thought I was really smart, because I could probably get $400 for the Graham Slee on Audiogon. I put in the Mani, expecting it to sound about the same or better, and damned if it didn’t actually hurt - the midrange was harsh to my old ears. I sent it back, with a 15% restocking fee and $28 return shipping. So now I’m into phono preamps for $525. I think my teenage self would approve, but damn. My ears aren’t what they were 40 years ago. It’s all backwards. I should have had the good shit in 1980 and the crappy stuff now.
