First I tried the Valhalla power cords. I could not believe what I was hearing. I was so impressed with what I was hearing that I figured I should try the Valhalla interconnects and speaker cables.
At first I just installed the interconnect between the DAC and the pre-amp and lived with that for 3 weeks. Wow, things sounded a whole lot better.
Then I installed another interconnect between my pre-amp and my amps and also hooked up the speaker cable. This really took my already great sounding system over the top. It was a learning lesson in what neutral is. The system is more detailed and relaxed at the same time. Things just sound more realistic then ever, with vibrant texture of tones, bigger sound space with air, air, and more air. Highly recommended!
Hope you find what works for you.
All the best,
Tom
