Got my curious USB regent link. It's had 24 hrs burn and so far I'm impressed how good it is. It makes a bigger improvement than expected and exactly as people described.

The first 3 I mentioned are not massively expensive. Less than $200 or £150. The others are a lot more!

Probably a lot more involved i.e. the purity and OCC. Also specific shielding. A lot at USB manufacturers use silver such as Oyaide, Neotech, Cabledyne, Wireworld platinum and Audioquest Diamond. I have the Oyaide Continental (5N purity) and the Cabledyne premier (6N OCC).

Hi all, The signal wires are silver. I have just ordered the 200mm regen link between W4S Recovery and Naim Dac V1. I'm hopefull for good results!

thanks for the reply. It costs twice as much and the standard smps will still pollute the mains!

Hi, I'm Glynn. I listen to headphones quite a bit so not to disturb the family! I'm currently using senhiesser hd600 with uprated kimber cable, via Shiit magni (with linear power supply and neotech mains cable), naim dac v1, inious zen NAS, oyaide silver sub, Ifi ipurifier2, kimber KCAG...

I really would like a 24v Ipower. Any chance these can be made available if there is enough interest? It seems like a popular size.
