Bulk cables: Oyaide vs Furutech

I would also consider Neotech bulk AC cable.

AC terminations can also affect the sound of the DIY power cables.

The initial suggestion to contact VHAudio is a good one. Discuss the best choices for what you want to accomplish with your longer PC. He carries most of the best terminations as well as Oyaide and Neotech bulk cable. Don't know if he carries Furutech bulk cable.

Another excellent source for DIY cable supplies is Sonic Craft. I know they carry Neotech and Furutech bulk AC cable as well as most high quality AC terminations.

I have used the Acrolink 6N-P4030, can make a very nice PC depending on terminations. For DIY, a very easy cable to work with.

I am currently using Neotech NEP-3001 and NEP-3002 PCs in my system. Have also tried NEP-3003. For DIY NEP-3001 is a bit tough to work with while the NEP-3002 and NEP-3003 are easier. IMO: If it matters, 3002 and 3003 are better shielded than 3001.

If you can find the Neotech NEP-3200 bulk cable, it's also an excellent power cable. More solid core than stranded as the others mentioned and teflon insulated. Probably better suited for amps.

Oyaide 004 are very fine terminations, no doubt about it, but may not be the best choice for every system.
