Give the new cables additional 2-3 weeks of play time after the initial burn in by upscale and enjoy.
I am hoping to try the Valhalla 2 speaker cables one day but that won’t be very soon
As to Nordost lines and mixing with other cables…
I use Frey 2 power cords on DAC and amp. I’ve tried a lot of different power cables over the years, these are the best do far. Looking to try Tyr 2 this year. Interconnects are Tyr 2 XLRs. Again, I compared a lot of interconnects and these sound the best to me. Speaker cables are Audience FrontRow. So mixing and matching is key. The system sounds ridiculously good.
