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,

Thanks for your responses!

What confused me about the BL1 is that it does not have a shield but rather is a twisted pair with a drain wire (as opposed to coax that has one wire with shield)

@williewonka what you mention is interesting. One of my sources is a VDAC2 (w/ VPSU)  and that uses a C7 (figure 8) connector without ground. In that case you are suggesting using the end with the shield to my amp?

On a slightly different topic, I am also trying to assemble a power cord for the VDAC2. Since its a C7 it does not have ground and only requires 2-core cable, but the bulk wire I found was only 3-core (I bought some Furutech). I wasn’t sure whether to just float the ground wire on both sides. I asked Furutech support and they said to do it that way

Right.. but do you use that shield on either end?
I thought you only use the 2 wires + drain
@williewonka Thanks for the detailed post and links. Those designs do look interesting although seem a bit more complicated than what I can get into currently but will reference them surely in the future.

I’m starting my first DIY IC’s now with Mogami 2534 and BL-1 as stated in this post and will be doing some comparisons between the two.
For the Mogami I used Neutrik Profi and the BL-1 will be terminated with Furutech FP-126.

I am a bit regretting not getting the KLE. I’m not convinced there should be any noticable difference (hence comparing myself) but they do seem to be recommended all over.

I am also planning on assembling a power cord with DH Labs Power Plus and standard Marinco connectors.




I haven't used the Furutech 126 yet, so I could replace for KLE Copper Harmony (within my budget).

Based on your experience, do you think that would be worthwhile with the BL-1?
I'm using DH Labs BL-1 between my Creep CDP and amp and a DH Labs power cord for my amp.. but not Thiel speakers.
I was using Neat Motive 3 and now experimenting with Monitor Audio GX50
This is quite interesting actually. 

I built 2 IC's, one with Mogami W2534 and Neutrik Profi, and one with BL-1 and Furutech FP-126.

Listening with my Senn HD650 (Creek 5350SE amp + Creek Destiny CDP) the BL-1 is very bright, even harsh sometimes.
This is odd because the Destiny is a very smooth player and the HD650 have the reputation of being rolled off the top.
At first I thought this was because of a recent recap of the CDP, but I dont have this issue with the Mogami IC.

I am reluctant to conclude that the BL-1 could have such an impact, but there is no doubt that the sound is harsh with that cable. It is very noticable (painful in the ear at moderate volumes), and that is not the case with the Mogami.

Wondering also if the Furutech RCA may be the difference here and not the cable
