I’ve not heard DH Labs signal or power cords in a while. I did have their AES/EBU, SPDIF Coax and USB digital cables. I thought they were excellent value.
I use Nordost Heimdall 2 power cords on streamer and Frey 2 power cords on DAC and integrated amp. DAC drives the amp via Nordost Tyr 2 XLRs in my system. Well balanced cables with natural tone that don’t emphasize any particular frequency. Very transparent. I have compared these cables to similarly priced Kimber, Audioquest, Acoustic Zen, Analysis Plus and several others.
Now what does this tell you? Just that I like them in my system in my room. How these will compare to DH Labs only you can tell when you do the A/B testing in your system. That’s the only way to find out.
