So I've been thinking about upgrading the cable on my Sennheiser Amperior and have two oprions. Buy one ready made for around £45-60 or try my hand at a DIY cable. I'm handy with a soldering iron so that's not a problem but I do need some guidance with the wiring. I've seen the parts I need on eBay UK (Cardas HPSC, silver cryo cable and 3.5mm plug). How do I go about wiring it all together? And what gauge cable do I need? Any help much appreciated! Thanks.
