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.

After reading and following this thread from the beginning, I still fail to understand how a fraction of an ohm (or a few milliohms for that matter) can have such a profound effect? When you consider the average speaker's actual impedance curve does not adhere to the rated impedance. My 10GA cables are estimated to pass around 60 or 70 amps. Will a 300A rating make difference? Do I risk the threat of copper thieves breaking into my house and stealing my speaker cable? Please excuse my rambling
geoffkait may be right (mark this day in your century calendar).

This is from some cable test where around 50 people showed up. Obviously, those are people more obsessed with audio reproduction than average. Out of them...

 "55% of voting audience uses bulk wire (not branded) on their home systems. Of those that use branded cables, 72% cost $500 or less per set in retail dollars. Therefore, 13% of audience use “expensive cables”, 33% use branded cables $500 or less."

Good info! Winter is coming. Maybe with 4/0 cables, I can jump start my car using my (10 output tubes per monoblock) OTLs playing some heavy metal?

DF is an amplifier design and making matter that may advertised whatever they felt its right.

The high DF is all about controlling the speaker. In electronics, the common idea about it is: the more the better. (Just the opposite of THD or noise: which is the less the better). However, some likes better the sound of amplification with higher THD and very low DF: tubes. That’s Ok too.

The new kind of D-class (digital amplifiers, using direct DAC as PWM) have DF of 5000! Even thou those need to be related more like a DF of 1000 (way of calculation).

I'm not into say what amp is better for you (it might be another thread) but I do say, for the amp you already own, what would be the best speaker cable.

Mr. flapjack

What could be better than a dual purpose cable?

If you would read my thread, you could already know that tube amplification have a very low DF, so you could practically borrow your line phone cable and use it for your speakers. If that would be also a long one, you could use it in between listening to your tubes and speaking on the phone, to hang your wet laundry.
