3 months ago I bought one of those pricey so-called audiophile fuses.
It took 6 weeks to make delivery from the other side of the Atlantic, and when it arrived, I set it aside and forgot all about it until last night. So I plugged it in to the back of my DAC-10 and not expecting much... I have to say I am quite pleasantly surprised. The difference isn't so subtle or merely "different" - but cleaner and clearer, and definitely more spacious.
