'Qute owners - How important is the equal length 'speaker cable requirement

Posted by: jobseeker on 29 October 2012

I'll shortly be the owner of a Unitiqute to add to my Superuniti. It's replacing an amp which had uneven lengths of standard 79 strand cable fixed round the lounge, which I don't particularly want to pull out and replace if I don't have to. I just wondered if anyone had any idea how critical Naim's recommendation of equal cable lengths was in this scenario.

Hi,

 

I think you will find that most if not all manufacturers will say that cables should be the same length; in Naims case they use the cable to load the amp correctly.

Yes, I'm aware of that general advice from Naim and wouldn't question it for the likes of the nap amps. However, the Uniti series amps aren't dependent on minimum 3.5m lengths of NACA5 or, indeed, NACA5 at all. I wouldn't even consider bothering about equal cable lengths for most amps and it would be a particular nuisance in this particular instance. Still, if I must then I must.

a metre or two will not effect the resistance of large csa cables

Hi Jobseeker You could always try adding a bit on to the shorter length to even them out. Should be cheap enough to try out (or free, even, if you have some spare - I know that I have a few lengths of QED 79 strand in the loft) and you could then see for yourself if it makes any difference.

I bet it doesn't matter, although I usually have my qute connected to 3.5m of NAC A5. I do sometimes move it to my other system with qed 79 of uncertain vintage and it works just fine there too.

Actually, I've found a spare length so I can even them up with a bit of effort getting the old cable out. However, i've noticed that it's QED Micro, which I think has rather less than 79 strands  Should be interesting.

Just when one thinks he has heard all the NACA5 jokes along comes a world beater.

Add a bit to it and see.

 Brilliant.

 

Actually, I guess what I wrote isn't too clear either. I have a full length of cable to substitute for the short length, so I won't need to add any. Maybe I'll leave the original length in position to save getting at it and just leave the new length on show (though my wife will NOT like that). However, all the cable that I thought was 79 strand isn't - it's micro, so will have rather less copper I think.

Oh dear, QED Micro. I usually show it to customers, then beg them not to buy it! It's dreadful. 79-strand (or QED original as it's known) is way better.

 

The cables should be the same length. If they're not the same, then the oddness that comes (usually a phasey sound almost lke you're lustening at an angle) depends on how much difference in length there is. My experience is that a few inches in several metres doesn't make a significant differene but 1m in 6m makes quite a difference.

 

But if it's Micro, I doubt it'll make a difference anyway! Give it a whirl and see how you get on.

Frank.

I've just found 2 x 4.4 metre lengths of original Proac Response loudspeaker cable at the back of the cupboard. Now that's got some copper in it ! The ends look tarnished so I'll have to strip it back. Mind you, it'll be a beggar to install. To be honest, with the lounge set-up as it is, no one will notice any improvement. There's just a couple of Audio Pro Qubes at each side of the sofa, reflecting the sound up off the walls. It's fine for casual and background stuff though.

I disagree with your assessment of the Uniti series regarding cable.  They are just as particular with cable.  They like Naca5 just as much as the amps, and in longer lengths.  We tried to use a short run on a Qute and it was bad. Bright!
And yes, equal lengths, even on a Uniti.

I think the point about some of the newer amplifiers is that they don't need NACA5 for stability, even if they benefit from it in terms of sound quality.

Hi,
That's not what my dealer told me.
It even sounds best using its own supplied connectors. I know, I had other quality bananas on first - not as good.
