ASR helped A LOT.
I bought some generic brand high-quality USB/Toslink/XLR/Power cables, replaced all my old snake oil “Hi-Fi” cables, sold them to some willing buyers (oops), saved tons of money, which actually gives me better (at least same) sounding devices with less money.
It's crazy to think that there's basically no correlation between price and performance in the Hi-Fi market, I used to think that higher price must mean better, how foolish…
Also, this gives me a “bad habit”, I refuse to buy any device without seeing third-party measurements first nowadays, I don't trust my own ears anymore…
