Owned Shunyata Sidewinders, then went to Kimber PK10 Golds which on my system and ears were an improvement. Later went to WyWires Silver and Platinum Juice II PC’s and very happy with them. Own all three variants from the standard, to HC and Digital types. Great power cords for the money, especially on the used market. Been moving my IC’s and speaker cables from WyWires to Nordost but probably stay with WyWires PC’s. I do own one Valhalla 2 PC which is definitely better than the Platinum PC but the WyWire holds its own very well and was a lot less money. If you’re looking to move up I’d consider the Platinum Series.
I use a WyWires Silver Juice II Digital PC on my Teddy Pardo, and all digital devices as well. Platinums HC’s on power amps and Silver Standard and HC and preamp and other components.
