RECOIL RCI23 100% Oxygen Free Copper 3ft 2-Channel RCA Audio Cable, Twisted Pair with Noise Reduction

Een beetje misleidend. Titel staat 4 kanaals rca 5.2 meter. Onderin moet je een keuze maken. Omdat ik gebundeld heb gekocht met de lc1 volume controller heb ik dit over het hoofd gezien.

How do you tell that an audio cable is good enough? With the modern Hi-Fi the quality of sound can be so great that it exceeds the capacity of human hearing, especially if you are over 15 years old. There are simple electrical measurements one can make to get objective data. A shielded wire has 4 basic characteristics that matter for signal transmission: central wire and the shield resistance R and Rs, capacitance C, and inductance L. The input you are connecting to has some impedance (usually 47 kOhm) and the inductance in series and the capacitance in parallel produce a drop at high frequencies. I measured 0.30 and 0.40 Ohm, 60 pF, and 1.6 uH for this 3' cable, which is pretty good. Relatively low inductance means it is made of stranded wire, and the capacitance is lower than most cables of similar brands. Also, relatively low capacitance means the cable is thick enough not to cause issues. The equivalent impedance at 20 kHz due to inductance is only 0.2 Ohm, and due to capacitance 133 kOhm. Compare the latter to your output impedance (usually 1.2 kOhm or less) and it is clear that the effects of L and C are negligible. One other thing is channel crosstalk. I measured 21 pF cross-capacitance for this cable which is very good: the crosstalk should be less than -50 dB. Had no issues once connected to a 6-channel input of my receiver.

Good quality. Works as advertised. No sound quality issues whatsoever

Good quality RCA. Would buy again.
