I tried all WBT Nextgen male and female(silver and copper versions),and Eichmann silver and copper at my own cables-WBT Silver sounds significantly better than anything else to my taste.Long break-in period-at least 100 hours before it start 'open'.Construction/price sucks,but performance is exellent-I never heard so many details on my familiar CD's-organic and sweet sound.WBT Nextgen female is great upgrade too.Just my 2 cents.
