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

You're right, sorry, I forgot cable length. The length is 2m for that system.

No, I'm not going to connect that receiver with two 0 awg wires, apologies for the confusion.

I have three "systems".
An HT/listening room: classe ct5300 -> 2.5m cable -> B&W 802
A family room TV: Sony DH820 -> 2m cable -> B&W 604
An office system: Class T amp -> 2m cable -> B&W 805

You could say I like the B&W house sound :)

The plan is to use 0 awg in the HT
Prior to that upgrade I'll try bi-wiring with my current 4mm cable. If that makes a significant improvement, and the 0 awg is an improvement over the bi-wire, then I might order more 0 awg and see what bi-wiring does with that. Again, that's all in the HT.

If the bi-wire in the cinema offers no improvement I was thinking about where else I could use that cable. I'm probably getting ahead of myself. I'm sure you're going to tell me not to bother bi-wiring with 0 awg anyway, in which case I'll likely leave it.

Thanks again for all this information and time. My new cable ships tomorrow so I'll tell you how it sounds and give you pictures later this week.

Mr. conradnash

I'll refer, with your kind permission to your HT system only. The rest doesn't worth the effort.

I've told you what cable you need. I took the time and the effort doing so.

If you have other ideas, you are welcome. I won't take the responsibility for that. I do not understand why you would ask for my advice and then do else. Is that sounds right to you?

Well if you go your way, it is your choice. However, it would have nothing to do with my thread. This is not a bi wire thread and I do not wish to keep that subject as topic here.

It may not benefit any of us.

@geoffkait , absolutely. While the logic and absolute-ness (in audio, indeed!) might not be agreed on by everyone, I’m an advocate of trying it and seeing how I get on. If bi-wiring has claims to work (ignoring any bi-amping, whether active or passive) then swapping the cable for one double thick run instead of two thinner runs should achive a similar effect. Maybe that’s what’s being seen here? Either way, agreeing that bi-wiring might work but this can’t seems like a contradictory argument.

>>>>Sorry, no offense intended, and I realize some will probably accuse me of shooting fish in a barrel 🐟🐟🐟🐟🐟 but you don’t have any more idea what bi wiring is than b4icu.

I appreciate your instructions and they're what I'm following. 2.5m of 0 awg. I'm really just thinking aloud about other possibilities.

Also, in the course of this thread I've come to realise that I can test out bi-wiring my 802s. But that's of no real relevance here, you're right.

To be clear, I'm taking your advice, I've ordered what you suggested, and that's what I'll feed back on. Thanks.

@geoffkait I think I know what it is, but I don't understand the reasons behind it offering any improvement. I'm no electrical engineer so I'm no position to talk about impedance, conductance, and resistance, or how the length, gauge, or number of cables alters their relationship. I'll freely admit that.

Like I said, I'll try bi-wiring as well as part of my experiments. I don't need to understand why it works to hear the difference.
