wires in the sgl-jr cable looks to be stranded copper in clear insulation. Though I am not sure if it is indeed stranded or just the extrusion marks in the insulation making it look stranded. Wire diameter 0.9mm, including the insulation. Wires look to be braided in some kind of flat geometry, lay loosely in the tech-flex sheathing. Any pulling stress is contained by the techflex, not transferred to the wires.
The plug end on my pair looks fine, not sure why Spritzer's pair (in his tear down thread) has an extra disc in the middle of the pins. I bought my pair used so don't know if the disc was ever there.
I did some more listening, using HeAudio Jade, 007 and sgl-jr .
gear chain is the same as above, except the output caps of SRM-1 changed from 0.22uf FT3 to "0.47uf miflex oil // 0.1uf FT3". The bass distortion problem previously detected with 007 no longer shows up.
Music was Fleedwood Mac 25 years box set ( 4 disc's in the set. I only had time to do disc 1, 2, and most of 3). The session stated with sgl-jr, then 007, then Jade, and ended with sgl-jr.
sgl-jr: the widest stage of 3. Maybe 50% wider than 007. The most detailed of the 3, a little sharp at times but not offensive enough for me to want to change anything. Didn't have the feeling of "wanting something more" or "something is not right", it was simply "good enough". Once the volume was set, I did not feel any urge to touch the volume knob. Just kept on listening.
007: nice warm sound, but even with all that warmness there was something in the upper mids (female vocal range) that bothers me. A little grating if you will. I turned the volume down and up and down again a few times trying to find a comfortable spot. I put the 007's aside after 30~40 minutes.
Jade: the Brightest of 3. Sound stage slightly wider than 007. Bass light, I felt the "want" for more bass all the time. Not as resolving as the 007; sound is smooth and I did not wish anything to go away, just the wish for something more (more bass, mostly). So I turned the volume up, to get more bass and more obvious details, but after a while the brightness got to me so I turned it down, then up again, then down again..... I suppose I could get use to the sound if I could control the urge of wanting more bass.
The 007 lasted 1/2 CD, and Jade lasted maybe 3/4 CD. The sgl-jr did the rest, and I could keep on listening to it, but by then it was already 1:30am.
