Hi There,
I've had a Rockna Wavelight for 1.5y now, and have been reading this thread. I wanted to chime in on the differences a fuse upgrade will make in the Rockna. I had a Synergetic Orange, which was a nice improvement over the stock fuse, but nothing would prepare me for the QSA fuse in the Rockna. I sprung for the violet fuse which is so crazy expensive, but OMG, after 3-4 days of it in the improvement of the DACs ability to portray the natural flow of music was amazing. The fuses are directional, and if after 2-3 days the change brings on brightness, the fuse is in the wrong direction. I find that the Rockna is sensitive to power cords. Back in Oct I got a great deal on a Synergetic Research Galileo UEF power cord. OMG - pardon the profanity, but I nearly fell off my listening chair. The room grew in size, and the soundstage widened well past the boundaries of the speakers. More importantly, the Galileo on the Rockna allows the DAC to scale up the size of the music hall, also very accurately placing instruments within their own space within the larger sound stage. the QSA is a nice upgrade for the wavelight. I was half temped to go all the way to the top of the QSA line, but cant justify that much money for a fuse. I dont think you will be disappointed with a QSA fuse, I would recommend either a yellow or violet, but some have mentioned the improvements are more drastic as you go up the line of QSA fuses.
