HiDiamond Speaker Cables

B- depends on how resolving your system is. The answer to your question is exactly what you would think it would be. Again, all systems are different. I now have p-4s from the wall to the P-10s and from the P-10s to the amps. Better than p-3s and much better than stock cord, which is still better than most other stock cords I've heard. P-4 is audibly quieter in my system. P-10 is audibly quieter than P-5 in my system.

Stevepo - curious to hear how you like the HD8's. What are they replacing and what are your speakers?

Stevepo,

The HD's sounds good right out of the box but will improve
substantially up to and over the 500 hr mark.

I'd say my ic's noticeably hit their stride at around 400 hours. Seems like a lot but one day I turned on my system and sort of went, "ahhhhh". I feel like they hit a plateau somewhere between 100-200 hours then Bam! at about 400.

Fplanner2000,
I have terminated my P3s with Oyaide M1 plugs and F1 IECs and the difference is night and day. Expensive but worth every cent.

Fplanner, I am reserving any commentary on the D8's until they at least reach the 100hr mark which should be by tomorrow night.
