I'm finally wiring up the Kaiju rebuild and I'm not happy with the signal wiring layout that I've committed to. The internal signal input wiring will need to be almost 20" -- from rca jacks at the back to a stepped attenuator at the front and then to the drivers near the center of the amp. On top of the 20" of internal input signal wiring is another 20" of interconnect between the Beepre and the Kaiju. So approx. 40" total per channel.
I did a bit of research on cable capacitance, inductance and impedance but found so much contradictory information that I gave up: one says cable capacitance has no impact on audio frequencies over lengths less than a couple meters, and that it's all about impedance; another says impedance doesn't matter and that it's all about capacitance. So I am confused.
All signal wiring will be copper shielded -- internally with solid copper tubing and the interconnects with thick copper braid. Unless I re-jig the layout by moving the attenuator close to the driver tubes, all I really have to play with is wire diameter and cable structure. My default approach is use 20 ga silver plated copper wire, twisted 3 times per inch, and then shielded with shield grounded at one end. But I also have some 30 ga wire on hand that I cold use if that might make a positive difference.
Question for the BH experts: any educated or experienced-based guesses as to my best approach (other than moving the attenuator)?
