No one actually knows how to lculate what speaker cable they need


It goes back to cable manufaturars, mostly provide no relevant data! to sales and the users. None will answer this!
Whay do you think that you own now the optimal cable to your setup?
I think I've figured it out.

Yes, exactly! Audioquest is a cable maker. And you are not. Polk is a speaker maker and you are not. Definitive Technology is a speaker maker and you are not. See the pattern? Furthermore, there is no financial advantage for a speaker company or an audiophile magazine editor to promote bi wiring. Hey-loo!
Mr. geoffkait

All the respected makers you have mentioned above have an interest. They make a living out of that, the more they sale the better. That’s called a biased testimony.

I don't.

See the pattern?

Bringing this back to topic, b4icu, did you say that this doesn't work on class D amplifiers? If so, does that also go for class T as well?

And what about for budget receivers and speakers, for example, I have this amp: https://www.cnet.com/products/sony-str-dh820/specs/ and B&W 684 speakers. What would the optimal cable be for that pairing, and, in your opinion, would it be worth it?


As for bi-wiring, I'm going to test my current cable in a bi wire set up. If that offers an improvement over single wire with a solid silver jumper cable then I'll compare that against the 0 awg when it arrives. If that sounds better again, I might even bi wire the 0 awg. If it works, great. If it doesn't I can use it in another system.
I guess you’re probably right, b4icu. It’s a giant conspiracy. Very carefully choreographed by big money - and it’s worldwide. Especially in the US. You see everything, don’t you? 😬
Mr.  conradnash

What is the difference between T and D class...? D class may have a DF of up to 5,000! Using the same formula, it would suggest a cable with a cross section of an elephant's leg…

I'll rest my case and not dig into those few who wend that way.
Most Japanese receivers have a DF of 40.

As you ignored my need for cable length, I cannot answer that question. The link for the spec does not specify DF.
I'm confused. Are you going to connect this SONY receiver with two 0 AWG wires? Please follow my say over this thread and then reconsider. Thanks
