What's the most overrated or overpriced piece of equipment you own, have owned or come by?

I regretted buying the Dynaco 416 amp with the outboard C-100. I had heard it in someone else's system and I was enthralled with the immense power and the flashing LEDs. I got it home and immediately blew out 2 pairs of speakers. But it wasn't until I switched it out for a pair of Mark III monoblocks that I knew I had made a dreadful mistake. 

I also regretted buying the Magnepan 2Bs until I got them into the right room and learned how to position them. 

But generally I buy used and more than 5 years old, so I don't get much buyer's remorse. The only exception to that is cartridges and CD players, which are the only things I have bought new in the last 20 years. 

But I am considering a NAS drive...

Odyssey Audio. By far the worst company and the worst products I have owned. The most positive thing I can say is this; After owning three pieces that had hum and buzz coming from the transformers and not getting in touch with the owner (no returned messages)  I finally reached him and returned the gear. It came back with the same problems. Mr K. lectured me on my power problems, even though countless pieces of gear never revealed this problem. So after years, not months, he agreed to buy it back at a huge loss to me. That is the good part.

I know there are fans, but I cannot see it from my vantage point.

2psyop: Sorry you had such issues with Odyssey Audio. I purchased a Stratos HT3 from Klaus (actually a one-off with new circuit boards for the L/R channels and an old board for the center channel) with cap upgrade following a little negotiating at an audio show. I had a hum problem as well. I was able to get Klaus’ assistant on the phone, and he walked me through the process of removing a ground wire inside the amp that he suspected was the issue. It was indeed the issue, and since then, which is about 10 years now, the amp has been totally silent. I did have one capacitor fail early on. While Odyssey Audio gladly and quickly replace it under warranty, I was a little upset by the large shipping charges required to send the 64 lb. amp to Minnesota. But overall, my experience was far better than yours, I think. FWIW, I love the sound of the Stratos. As they say, YMMV.

Everything I own was well worth the discounted price I paid. I seldom settle for paying the full price for anything. 90% of what I own was bought brand new. Some of it 30 years old or more, and still working. My Tannoys I bought at a great price, due to dealer error. I was supposed to receive a used pair, but a salesman sold them not knowing that they were set aside for me. Turns out, to make all good, they sent me a brand new pair fresh from the Tannoy factory in Scotland! That was a Happy day.....

I had a pair of Bose 901s.I bought used in mint condition for $315 ,they were fair traded back in 1972.When set up right they sound Great...I don't know why people hated them...lol....but they do sell alot of overrated garbage...lol
