So my Nordost Heimdall 2 Power Cord & 1m BNC cables finally arrived. I was using an old Shunyata Venom and the stock BNC cables previously. I honestly was not expecting much improvements to sound, if any at all. For me, it's a completely obsessive-compulsive thing where I just want all the audio cables to be Nordost. Since I'm not going to waste time A/B testing, I don't know whether it's the BNC cables or power cord that made the difference. I'd say for the amount of money spent, for most people, they're better off getting a Hugo 2 if they don't already have a portable DAC/amp. I'd say the sound is slightly better with the Nordost cables. The vocals and sonorous instruments sound smoother. The background is just a little darker/more silent. The soundstage and instruments are just slightly more 3-dimensional. And the micro- and macrodynamics are also slightly better. The sonic improvement really sounds more like what I got when I changed my power cords to Nordost or when I switch to Uptone LPS-1 to power my video sound source or me switching to the the Nordost power bar. So my guess is that it's more the power cord than the BNC cables that made the difference? Not sure. I think unless you're really obsessive compulsive or you're just really into cables and tweaking sound that way, I'd probably not spend a lot of money or time on different cables. But then maybe I'm lying to myself. All audiophiles tweak cables and are obsessive compulsive?
