I used to notice a difference in times of day until I got a puritan 156 power conditioner. In my case, I plugged everything (amp, preamp, phono, DAC) into the puritan and the sound improved considerably. The Valhalla 2 are outstanding cables and in my comparison to several other brands, were far superior. Also, consider having a dedicated 20A line to your music room. This too can make a large difference. Hope this helps.
Nordost Valhalla 2 - Susceptible to Noise?
I was over the moon with the improvements my Valhalla 2 speaker wire brought to my system, until the next day things didn’t sound so great. I thought maybe my first impressions were overblown, until I tried again after midnight and that glorious holographic soundstage re-emerged.
It seems that the Nordost cables are so resolving that I blatantly hear differences in power quality, and I’ve since gone down the path of investigating power conditioners.
But that’s another story. What I’m wondering is whether the Valhalla 2 cables themselves could be more susceptible to RF/EMF noise, given their unique ribbon design? And, if so, is their any way to deal with this issue?
I’ve seen some folks using Alan Maher’s Circuit Breaker Filters which you can simply tie to pretty much anything, but they don’t seem to be on his site anymore.
