Your single most significant purchase mistake?

Back in the early 2000's I bought a Crown amp getting rave reviews, 1000 WPC. It lasted a week in my system, I let my friend try it to buy it he gave it back. Rather shrill sounding and good bass.

I also had an NRG Control amp after that and it sounded ok but was built poorly.

"My ex wife."

Very tacky technik.

Lol @fthompson251 

They’re great for PA Systems and or supplying the muscle needed for Home Audio sub drivers, but that pretty much sums them up.

Biggest Regret Purchase: Magnepan MGIII speakers.

There was a recent thread regarding McIntosh and a lot of folks trashed the brand. Interesting that only one mention where someone bought a Mc product and did not like it!!! FWIW I do own and very much like McIntosh.
