Recently I bought
**** 16 cores cable for TFZ T2 during AE 11-11 sale. I bought it simply for the look as it looks nice and matching the TFZ T2 blue color.

When I compared it with the stock cable, I didn't expect to hear any differences, but I think I did hear a slight differences between the 2 cables. The **** cable sounds a tad warmer with slightly thicker tonal density around the mids and bass. Just a tad, nothing significant. Out of curiosity I measured them to see if I can see any differences from the measurement.
I use China generic IEC60318-4 coupler (with mic integrated), and RME Babyface Pro for the audio interface. Rode VXLR+ converts the 48V phantom power to 5V plugin power for the condenser mic inside the IEC60318-4 coupler. For software I use REW latest beta version. I have done quite a lot of measurement with this setup, with small Silicone ear tips and proper insertion I could get less than 0.1 dB level matching between insertions. That means for the same driver, the level at reference point (in this case I use 1kHz instead of 500Hz) is pretty consistent between insertions and measurements. I usually do around 3 times measurement and re-insertion for the same driver to check consistency. So for example when I see the 1kHz level like 0.2 dB different between left and right channels, it is the difference in left and right channel matching and less of the insertion error.
I measured the **** cable (silver-blue) and the stock cable (black), the FR looks very2 close between the cables, so we can say FR is practically the same between the cables.
TFZ T2 Left Channel **** (light blue) and Stock cables (dark blue and light purple) - 2 measurement each cable:
TFZ T2 Left Channel **** (Yellow and Orange) and Stock cables (Red) - 2 measurement each cable:
TFZ T2 Left Channel with stock cable - Left and Right channel matching - 2 measurement each channel:
So FR wise no different between stock and **** cable.
But I notice the following differences in 1kHz level when I matched it to 95 dB SPL:
TFZ T2 Stock Cable Left: -18.90 dBFS
TFZ T2 Stock Cable Right: -19.50 dBFS
TFZ T2 **** Cable Left: -19.20 dBFS
TFZ T2 **** Cable Right: -19.80 dBFS
Those are the level setting of the generator in the REW. As we can see that with **** cable I have to set around 0.3 dB lower to match level of the stock cable. That means the **** cable is simply 0.3 dB louder than the stock cable, which translates to lower resistance on the **** cable. I haven't measured the resistance of the cables, but this is good enough for me to see that both cables do have measurable differences.
