Anybody here terminate DH Labs BL-1 cable?


I want to make sure I'm terminating these correctly.
They have 2 conductors, a drain wire and a shield.

For unbalanced RCA termination, 1 wire for signal, 1 wire for ground, and combine the drain on the ground wire?
Is that correct? Or is the drain only used for balanced connections?

Thanks,
Itsik

@williewonka I'm waiting on some cable then I'll be building a couple of your power cables.. I'm interested to hear what change they bring, if any. I'm currently using diy cables I made based on the VH audio designs. However, I filled the PVC tubing that contains the conductor and neutral with aluminum oxide powder to act as a mechanical damper. My conductor and neutral are silver plated copper..

Thanks for posting the designs. I love diy! I just made a y cable using your helical architecture and some plenum cat 5 cable for playing music from my phone. It sounds great and looks pretty. Which is more than I can say about myself..
@williewonka
I finished the cables and they sound great from the start. Though I think a lot may be attributed to the silver plug and IEC connectors. I have a DIY power box wired with 10awg silver plated copper straight through a DIY power cord like the VH audio cords. No IEC connector, just outlets to plug, which I upgraded to a silver Sonarquest during this project. My outlets (wall and box) are all Hubbel 5362 and I have a dedicated 20 amp line to the two outlets in my room, though i only use one. Unless I’m vacuuming.

I made 2 10awg cords.
I ended up using the innards from a power cable I found through your power strip post. It’s the place you purchased your chassis from: vt4c.com. I bought GY-PW8000, which only has two conductors and a smaller gauge ground, but the conductors are teflon insulated, monocrystal (whatever..) rectangular, multigauge copper. And they’re fat. My contact there said they were approx 11awg, but I found them to be fatter than 10awg, maybe not quite 9awg.

I bought the silver sonarquest connectors. It’s funny, my previous DIY cords also had sonarquest, but I hadn’t noticed the silver before.

The cables are for a dared MC-7P tube preamp and a crown xls-1500 amp. I’ll make one for my CD player next. I’ll probably give interconnects a try too, though just in copper so i can compare the sound difference to my current copper cardas cable DIY ICs. I’m a bit limited in budget, as you can tell by my meagre gear, but it’s capable enough for me to be able to notice differences in cables, especially now that i’m beginning to sort out room acoustics.
I think I will try the KLE connectors though. I'm curious how much better than the standard cardas silver plated copper they are.
@williewonka , I just wrote you a novel, but it wasn't posted for some reason. 

I definitely noticed more of a difference when I put a power cable on the amp than when I put one on the pre.. But the amp has a switching power supply, so I think they are more susceptible to current restriction..

I'm waiting on a small inline component before I build any new ICs.. Then I'll start messing with building them, as the component well require different terminations.

My speaker cables are DIY, braided cat5 plenum cable. 7 lengths braided to form a 9awg cable, terminated with audioquest silver plated BFA bananas. I love their sound..

Thanks for all your posts, by the way. They've been a great source of info.
Dude, thanks or that list! A great starting point for me. 


I could conceivably do helix speaker cables since I only need 5 ft cables.. Though might length differences in the + & - adversely affect the sound? I understand why they won't in the power circuit, but I don't know enough about the speaker output circuit to know if length differences matter. Do you?
 
Again, thanks for the knowledge.
