I found that the Cardas cable was better than the stock.
The Zu Mobius which is silver certainly gave the treble a boost.
The Equinox gave the best all-round presentation.
btw, I was a real skeptic until I changed to a Cardas from stock.
I also found that if you replace the foam with about 5 layers of nylon pantyhose cut to size, it lifts the treble considerably.
Without any foam I only last about 20 minutes before my ears get very tired of the presentation.
The other side may have a cheap aftermarket cable for sale.
