Re: Not Just a Review, but

I actually prefer to use a -120 dB floor for excluding effects, since a good amp or source usally has >110 dB SNR. Granted, you'd have to turn your stereo up to volume levels which would cause permanent hearing loss to hear differences that small, but a bit of conservatism when treating effects as insignificant seems wise. In general I'd say things which fall below a -60 or -70 dB floor aren't going to have a significant effect on my stereo's sound since my typical listening levels are in the 60 to 70 dB range. But there's a difference between significant and negligible.

I agree what ultimately matters is the sound. Any model is an approximation of a system; the value of a good engineering model is it provides useful information about design tradeoffs. In this respect an RLC model of the cable is a highly useful tool since it's an electrically small system and dielectric losses are negligible (specifically, for any cable I've come across the difference between an RLC and an RLCG model is HTML tag not allowed


What they don't capture is the change in cable structure at the terminations and the contact resistance of the terminations themselves, the latter of which apparently neither of us has data for and therefore cannot be included in the model. That's not ideal but I think it's OK; any cable has to be terminated and, assuming you're being fair and terminating all cables the same way, then to a first order approximation the termination doesn't matter in assessing electrical tradeoffs because any cable you choose will be affected equally.
