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

And...even if say for the sake of argument, someone uses 10m of these wires, then that is:

0.0252 Ohm for 10 m of 14 AWG
0.00093 Ohm for 10 m of 0 AWG

Who cares? You CANNOT hear any sonic differences due to this resistance difference alone! Electrically, this is chasing angels on a pinhead when it comes to an AC audio signal of a few volts, if that.

I'm sorry but this is biggest bag of (Maritime51 please insert here) ever concocted.

From what I gather a decent 0 AWG welding cable with suitable connectors (correctly attached) will work with 95% of the speaker/amplifier combinations negating the need for a top secret double probation yadda yadda formula.

Mr. stevecham

I see there is a big understanding gap you need to overcome.

The resistance of #14 vs. #0 is remaining relative, no matter of length. It will apply to any length from 1 m to 1 km or 1 cm.

Who cares? I do. You should too.

If we return to DF and assume it is high (500) it would represent an output resistance of 8/500=0.016 Ohms. (this been repeated many times along this thread).

A #14 wire of 3m long (actually it is 6m) is: 0.01512 Ohms.

That’s as much as the Ro (DF). If so, the actual DF is reduced from 500 to 264. It is half!

That’s why your amplifier investment and you should care.

If you spent $5k on that amplifier, you have just lost 50% of it, due to that poor #14 cable.

If you would use a #0 cable, you would get most of the DF, or the entire $5k you invested in that amp.

What that sounds like? Look at the sharing. More will hopefully follow. Try it yourself instead wasting your time and energy in something you do not understand. It is kind of $60 away from you. Nothing in audio for $60 will get you such an improvment. Ask Mr. conradnash or Mr. keppertup.

 

Mister b4icu...I met the esteemed Mister Low when talking to a sales dude about speaker cables at a nearby audio "salon" (meaning one of the few hifi joints left) and he introduces me to Low who's standing behind me. Low is amazingly passionate about this stuff...cool guy. I use a pair of 10 foot Rocket 33s (the cheapest of that line of cables) per Bill's suggestion (read the stuff on the AQ site about the bi-wire capabilities of these cables for details) from a 12wpc (likely more like 10wpc with the KT77s I prefer) Dennis Had Inspire Firebottle HO (it's a HO...says so right on the front) single ended amp into 99db efficient Klipsch Heresy IIIs. The resulting sound is magnificent. 

Mr. wolf_garcia

I never asked about how you met Mr. Low. Thanks for the sharing, I meet yesterday a chair.

Please be kind to answer my questions:

1. What is your amplifier? Tube (KT77s) What model and brand?

2. What is the cable length? 10 foot (3m)

3. What is your speaker? Klipsch Heresy III

4. What gauge is the cable he offered you? "Rocket" cable does not look normal on the outside" This is the most "technical data" I'd found on the Rocket 33s. The rest is even more BS than not normal looking! Very common on cable makers who are amazingly passionate to rip you off.

I would assume that with your Klipsch (I Have the Forte II with the same efficiency of 99dB/w/m SPL), the tube amp is a good match. The cable, unless it has some capacitance or inductive properties, any would be fine. For the rest of your say about Mr. Low, I would rather meet Miss Pamela Anderson. She seems to me way more "amazingly passionate"!
