Recently I bought Yinyoo IEM 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 Yinyoo 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 Yinyoo 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 Yinyoo (light blue) and Stock cables (dark blue and light purple) - 2 measurement each cable:
TFZ T2 Left Channel Yinyoo (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 Yinyoo 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 Yinyoo Cable Left: -19.20 dBFS
TFZ T2 Yinyoo Cable Right: -19.80 dBFS
Those are the level setting of the generator in the REW. As we can see that with Yinyoo cable I have to set around 0.3 dB lower to match level of the stock cable. That means the Yinyoo cable is simply 0.3 dB louder than the stock cable, which translates to lower resistance on the Yinyoo 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.
