Measurements and conclusion
Contents
We also measured this particular speaker cable in the Alpha Lab. We recorded the entire measurement session to give you an idea of the procedure. Of course, we will fine-tune things in the future and measurements may be added. But it gives a good idea of how we proceed.

LCR Measurements QSA Lanedri Ultimatum Infinity
What stands out in the LCR measurements of the QSA Lanedri speaker cable is that conductivity is incredibly high. 900 Siemens is a new record! That gives – obviously – low impedance. That helps with delivering tight bass. (In our experience). Capacitance is also particularly low at about 200pf. That helps in terms of speed and constant timing (propagation variation). And we see that again in other measurements. Inductance is fairly average at 1.8 to 1.6 uH.
Scope measurements QSA Lanedri Ultimatum Infinity
As expected, the response is pretty tight. The treble is a bit more rounded than on the Van den Hul The Nova. We hear some of that too, frankly. Not disturbing, by the way. The bandwidth is wide, as we see in the response measurements up to 10 MHz. Propagation time is very fast with 13.8ns. The propagation variance is also very small at about 0.3ns. This is impressive. Great work by QSA Lanedri.
The only thing we really can’t explain is the noise measurement. It is just weird. We hear a pretty black background. Not as black as the Kimber cables, for example, but still… However: the measurement says otherwise. We will have to look into that further.
