What's the problem?
Contents
Why did we actually immerse ourselves in the world of speaker cables? What is the problem we want to tackle?
Frankly, the urge to tackle it was born out of the well-known statements on forums, Youtube, Facebook (and sometimes on Alpha) that “cables don’t do anything”. That there can be no audible difference and therefore all cables are just the same.
Now, we’ve reviewed quite a few cables – both blind an ‘normally’, alone and in teams – and time after time we’ve been amazed at the differences they can make. It can lift a system from good to great. Or from tasty to blissful. Any enthusiast will recognize and acknowledge that.
How can that be?
Now, of course, the question is: How is that possible? Is the sound or character of a cable measurable? If so: where can we see that? Frequency response? Timing? Phase? Impedance? Or is it something else?
The advantage of a study like this, is that Ãf we can show where these differences come from, the discussion about the usefulness or audibility of decent speaker cables is also immediately over….
Hi team,
This is quite an amazing project that you have done.
I am trying to use this information to help my selection decision making on some new cables. My conclusion is that the Audiomica ones which you tested seem to be the best value in terms of price vs your feedback about their sound. And from the qualitative feedback it seems like those cables would play well with most systems. Is this a correct conclusion to draw from the testing?
I understand that I would probably want to try the cables out on my system to make sure that they fit with the sound that I like.
I am relatively new to hi-fi so I apologise if this is a question that is a philosophically wrong way to think about things.
Hi Leon,
It is corrent that the Audiomica hits a sweetspot. They deliver very decent quality for a decent price. They are not cheap, but they are very good sounding. And yes: we estimate that they will work in most system.
It is always wise to first try a couple of cables and – if you found your match – buy them. We never advice to buy anything ‘blind’. Always try before you buy!
Thank you for the response and thank you again for putting together this review!
Welcome!
I wonder, if the impedance of the cables would not provide a more significant perspective instead of individual values of R, C and L ?
Well. We measured impedance. So check it out.
Here (impedance vs phase):

is one cable data incomplete!
I see. Slp 14/4 phase. It was accidentally measured in rad. That’s why i left it out.
Hey Jaap, that is a really nice test with lots of information, thanks for that! Would it be possible to have it all into one table for a good overview, instead having to scroll through the individual pages? May be too much to ask 🙂
Keep up the awesome work!
Standard cable of 2.5mm2… I am using 16mm2 “standard wire”, 3m long. Very low resistance. That ticks one box. I guess I can theoretically calculate the inductance and capacitance. Wonder if these are of significant consequence at 20kHz. Maybe I can twist the cable to reduce the inductance if it has some impact.
Let me know how it turns out… ;-).
This is beyond – need to study it – not just read, to understand.
Thanks for including the “peasant” installation cable AudioQuest 14/4 – I use the more expensive version XTRM 14/4. My question is – how did you terminate the cable and in what configuration? I have it terminated with nakamichi bananas and connected in a star-quad configuration.

It is terminated with spades.
And, just like that, Alpha-Audio shoots to the top of the audio reviewer heap! The GOAT of tests and shoot-outs. Well done kind sirs, that was an impressive and Herculean effort!
Thanks,
Eric
Thank you Eric.
