What’s a mistake you made by being impulsive?


I’m looking for cautionary tales to curb upgraditis.

After living with the same speakers and integrated for 20 years, I’ve now replaced everything in the last year. I even have a list of next steps that may or may not be necessary. Like I probably should finish mounting all my acoustic panels before getting a subwoofer. And do I really need a better pre if I only use one source and might eventually upgrade to a DAC with volume control? Did I mention I’m waiting for new speakers to ship? But SET amps sure are interesting and now I want one of those, too.

So when did you make a purchase and then immediately regret it because you decided to go a different direction?

I bought a high end surround sound preamp, big mistake. Mixing analog and digital on one chassis, simply a bad idea. OP you need a subwoofer and isolation platform, forget the panels.
I would say impulsively buying and flipping cables for a few years, I eventually made myself stop and very happy with the loom I have now.
The Krell KSA 400 integrated amp. Took it home for a weekend and it was the most amusical device I’ve ever heard. Had the famed Krell bass slam but everything was garbage. 
@nmmusicman My thoughts exactly about Krell amps in general, which was a bit of a surprise the first time I heard a Krell amp given all of the positive press that they get. I guess how each of us listen is different.
