1. I trusted my mother. I went to college. She said she would pack and ship my LP’s, less than 50, so I didn’t need to take them. Nope. Jogged a memory, I should have known better. When I was younger at summer camp, please send batteries, nope.
2. Went to Church Christmas Eve. Got ransacked while gone. They took my AR2x speakers, I’m still mad.
3. Pioneer 6x9 car speakers. Commuting to Philadelphia, 1hr 20 min each way for a while, I wanted to improve the sound in my 1961 VW Bug. They sounded fab in the store. Bought em, put them in the space behind the back seat, excitedly test, what the heck, no bass? Took em back to store: these no good! Guy says "Were they loose, or mounted in a panel? That’s when I learned about the back wave cancelling the front wave. Made a plywood panel, put em in, wonderful!
4. Waited, should have pre-ordered replacement tweeters. My son had some great parties here. EVERY time, they blew one or both Dynaudio D21 tweeters of my JSE Infinite Slope Model 2’s. They would hear nothing, juice the volume up, up, then figure out they had the wrong input. Bang, blast, burnt the factory tweeters. It cost him $60 or $120. each party. After research, I substituted a Focal tweeter, they could take a shot.
5. Trusted my evil stepfather. Mother divorced him. He took a collection of about 100 classical LP’s that had been my uncle’s. (my uncle died young, that’s when I inherited the Fisher President II console). Stepfather put them in storage in Maine. He agreed he should not have taken them, said he would drop them off with my mother. Lie, lie, lie. Then he stopped paying for the storage, the owner confiscated everything, nobody knows where they went.
6. Bought several used LP’s over the years, unknown artists, based on the cover design/notes. Some god awful. Now, I look stuff up on my phone when I need to.
........ other poor judgements I am sure ....
