Okay so my impressions on the HD800 copper(ground)/silver(signal) cable and Toxic company (Frank):
The communication with Frank was swift and informative, no wonder he is overloaded with orders, people appreciate these two things. Intravenous feeding comes to mind...
I will not go into detail with sound, the last time I posted my impressions on opamps in Auditor's power regulation section how it changed the sound....yeah I won't go into that but I will say this; I think the sound is not as bright as it was before even though both the stock and Toxic cables are SPC.
I asked Frank for some slightly custom stuff like longer cables between headphone connectors and the y-split and he made it perfect. I also wanted shorter heatshrink under connectors and was surprised by how he finished connectors, very impressive although I think even if there was zero heatsrhink there wouldn't be a strain relief issue anywhere. I'm just not a fan of heatshrink.
The cable aesthetically is beautiful but that's not why I bought it, I bought it for ergonomic reasons and there is scores a 10. There must be a gazillion of tiny strands, its that flexible. I hope it lasts long before copper starts oxidizing and SPC eventually as well. Since I won't be disconnecting cables much I am not worrying air would come in and do damage any time soon.
I will eventually order a HE-500 cable from Frank as well but a new phone comes first as my contract expired and I am still comparing silver to copper before I make a final decision.
Here are two photos I took really quick with an ipad:
Edit: I forgot to add that Frank was kind enough to add 3 rubber thingies that hold your ipod/amp/dac/shampoo together. That's exactly what I needed when I needed as I went to Tuscany 2 days later with my stack.
