I will admit I do have some regrets. In one way, I got to hear details that I hadn't heard in really cheap buds and speakers. And I did learn quite a bit of things about audio over the past few years. In another way, I became more focused on finding the "perfect sound" rather than listening to the actual music. I tried a few IEMs and headphones, only to be disappointed. Nowadays, I wouldn't feel as happy spending more money on high-end equipment and thinking about what "pairs" with what. I have been much happier just listening to my HD600's and even cheap stuff without thinking much about its flaws.
