Your single most significant purchase mistake?

Aurender N100H. Unstable, couldn't withstand power outages, factory support that couldn't be bothered to read the user's email complaint. Dumped it at a loss through TMR because I couldn't with a clear conscience sell it directly to a fellow audiophile.

I had purchased the N100H new from my ARC dealer. It wasn't defective other than arguably by design. Ugh.

early class d mark levinson mono blocks circa 2006/7... omg... how can something that looks so pretty sound sooo bad...

@mijostyn ... the missus is on line 2 holding for you...😂

mijostyn - I like the way you think😎 although I have many more mistakes. For audio, selling my SAE X-25A.
