I am considering selling my modded Grado SR80i's, recabled with one of Chris_Himself hybrid cables (SPC OCC copper for signal and OCC copper for ground). Only selling  because I have a recently built pair of magnums.
 
Would trade for Objective O2 amp, Grado RA1, or other similar amp. Maybeeee for an interesting pair of closed back headphones.
 
What you get:
Grado SR80i drivers, cups, confies, and headband.
Cable (retails for +-$100):

1. Hybrid (SPC for signal, OCC for ground)
2. 4+- feet long 
3. MDPc-X black sleeve
4. Double Helix Cable 3.5mm plug
5. Wood Y connector 
6. Great look, and feel.

 
I think the cable improves the sound in general. it adds little more detail and instrument separation. The bass response is improved ass well. I am very happy with the results.
The cups and the drivers are in perfect working condition, and sound GREAT. The cups do show some usage marks, as shown in pictures. The cable is basically new, and has been treated with care.

 

Ok, let's try something different: Who wants parts?

 
Only the cable left.
 
Cable: $89
(retails for +-$100, and waiting time for building)

1. Hybrid (SPC for signal, OCC for ground)

By the way, I haven't taken them apart yet. If somebody is interested I will do so. Still looking for some of the amps listed on top. I pay shipping anywhere, you pay paypal fees.
