I just got my aurora cable (not cheap at ~US$130) for my UE TF10. This is similar to Athena (8-way braided) but more expensive.
My initial impression:
1. Bass: It made the bass more pronounced. Not louder but it gave more definition to the bass)
2. Mids: I noticed a remarkable improvement on the mids. It has brought the mids of TF10 forward.
3. Highs: No improvement (highs are as good as it get even with the stock cable).
4. Soundstage: Same with stock cable.
I noticed however that it introduced a bit of sibilance, especially for the mids.
To close, I did not expect that a simple cable upgrade will change the signature of TF10. Is it worth the price? Well, that depends on how deep your pocket can go.
No buyer's remorse for me however
