Has anyone else auditioned something that really was terrible?

Someone noted that he was surprised by the fact one of us did not like a KEF LS50 speakers.  After all, reviewer Steve Gutenberg uses them as a reference.  In a YouTube video. Nelson Pass shows his reference speakers, stating that they are not his best speakers, but are the best he has to show the differences between electronics.  Steve G did not say they are great.  He said that with the right sub, someone might be happy with them.  That is not a great endorsement.  

The worst system I ever heard was at a friends house. Before I tell the story, I'm a firm believer that we all hear things differently. Because I don't like it doesn't mean it's a bad product or that I'm right and others with differing opinions are wrong. I think that if you had 3  people in front of a system there's a good chance that you will get some differing opinions among the group.

My friend had been going through equipment trying to find the best fit for him and spending a lot of money churning gear. He acquired a very highly reviewed system and invited me over to hear it. Well I spent 20 minutes squirming in his listening chair and he finally asked me what was wrong. I reluctantly explained to that for me the sound was so harsh and in your face that I couldn't listen to it. That's a hard thing to tell a friend. In any case he ended up selling the system a few weeks later and downsized quite a bit to a system that sounded much better to everyone who heard it including his wife.  He has had the same system for the last 9 years. I won't name the products because I am sure to get flamed. My friend started a discussion on this when he sold the gear and the distributor had AGON take the thread down. 

The lesson I learned is not to buy anything that you haven't heard in your own listening room, if possible.

Well... I lusted after the original Revel Ultima Salon’s for years - highly reviewed and rated as A+ . Heard them many times at dealers and shows and dismissed the dull sound as associated equipment or room. Finally against what my ears were telling me I purchased my Salon’s... three amps, four pre-amps, and two different rooms later I sold them.

I do have a friend that own’s a pair plus the new Salon2’s as well and likes them very much. So hold your flames, clearly my ears are broken hence the name tinear123

I dropped by a local audio boutique a few years ago and they were demonstrating the then-new Wilson Duette stand-mount speakers. I don't remember the electronics they were connected to, but they were decent, but the sound was bad - flat and no decent treble. Then I looked closer and saw that the source material was from a laptop computer. I think they were using the audio straight out of the laptop's sound card, though I can't be sure. To be fair, it may have belonged to a customer who brought it in for a demo, but it did the Wilsons no favors.

How is GoldenEar not on this list like 5 times already? I have never heard something so well-reviewed that sounded so bland and with such poor imaging. We were a dealer for them temporarily, but couldn't sell them with a good conscience.

The other one is the Raidho D-1. We transported a set for a client from one house to another about 5 years ago and they sounded so bad I thought we may have damaged the tweeters. Seriously. We brought them back to the office and played them on 3 different systems for multiple employees and everyone agreed they just sounded bad. The B&W 805D absolutely crushed them above 80Hz. We even sneaked the 805D into the client's house while he was away and played them on the Zanden gear he had and the B&W was still way better. We told him we were concerned about the Raidhos which is why we brought them to our office to be checked out, but we couldn't find anything physically or electrically wrong with either one.
We never tried to sell the client on the B&W because we didn't want it to look like we were poo-pooing his gear. We just reconnected his D-1s and he said they sounded as they should. We were all shocked.
