In the last year I build a new no 1 sound system with Raidho X3 and upgraded another one with Q Concept 500. In the process, I tried various speaker AND power cords. The latter have a big influence on the sound balance, i.e more or less open . Here are my findings for power cords. I will talk about speaker after
Audioquest NRG, Blizzard and Dragon: sowhwhat darker sound
Luna Mauve: also dark, but with a lot of oumph in the bass. More solid low bass.
DR Red Fire Ultra: great highs , cristal clear, but thinner bass, less free flowing.
Siltech Classic: Bingo the ideal solution: higs as good as DR and strong bass like Luna.
Same conclusions on both systems.
Speaker wires now:
For the Raidhos, I tried Transparent Super and Luna Red. The latter is kind of smoother, more liquid or organic sound. I kept those.
For the Q concepts, I got Tranaparent Ultra, biterminated to replace the Supers. I was stunned by the difference. Suddenly I had the feeling to be in the mixing room of a friend's studio years ago, listenning to a band playing in the studio , the sound going from the microphones to the mixing table to the monitor speakers. Wow. These cable brought me closer to the sound of live music , a lot.
My advice: experiment, borrow cables and try them. You will learn a lot and have fun doing it. There is no better cable. You just need to find a good match.
