Hi Peder, I have a few HB power cords, they are very musical, reasonably neutral with perhaps with a little warmth when used with the standard/supplied connectors. I personally found that the connectors were limiting the performance of the cable somewhat when I replaced them with Furutech NCF connectors (Rhodium ), then they become even more neutral but the noise floor drops significantly.
If you wish to still retain a little warmth then try the Furutech NCF but gold plated connectors, or just one NCF gold at say the ICE end. As I bought them very long time, just about when they were released, the price was reasonably fair, but not sure how much they are now.
But they are good, I have bought a couple of Stealth power cords at 3-4 times the price and they are better than the Vertere HB. But Vertere HB offer very good performance for the money. I have not tried the HBS as that seems to be sold exclusively in the Asian market.
Hope that helps somewhat…
