No Brainer upgrade to my NACA 5

Having been considering cables for a while, I phoned Sondek Meister Colin Macey of Martin Kleiser to discuss my speaker cables. He sold me my first Naim kit around 1990, and the NACA 5 that went with it. Cutting to the chase, he made a suggestion that I thought worth a try - so I hoofed over there lunchtime to pick up the cabling he suggested for a loaner.
To be truthful, I was a little sceptical - but I did get the chance to hear Marilyn Manson's mOBSCENE through Komris.....mmmmm.... but anyway.
Unplugged the old, plugged in the new....INSTANT improvement of pretty vast proportions. We are talking about BIG TIME changes here. So far since then I have been listening to Kate Bush in the main, more later, but wanted to post on this soonest; everything is clearer and more defined; instruments that where hinted at are now placed correctly, audibly,, and rythms ( how IS that spelt, Herm? ) that where down in the mix are now revealed. I was converted in a very few minutes.
The naim of this cable? NACA 5.
It is this simple. If you have old stuff, it will degrade, it has degraded, it is not at its best. I did not believe this; I thought that the oxidation spiel was a hi fi bluff. It is not.
This is an incredibly good VFM upgrade - I recently went 82/HiCap to 82/Super; the improvements from new cabling are probably 2/3rds the jump from Hi to Super. It really is that good.
Make me 5 meters Mr Macey- and are you ever wrong?

Mike,
ive just had similar results. I changed my turntable, arm, cartridge, pre/power amp, speakers all cables, stands, carpet, lampshade, ears and spleen for identical items. The difference is incredible!!

I think nipping the oxidised ends off your old Naca5 and reterminating it would have yielded similar results for less money than replacing the whole cable.

Steve.

I agree with Steven. If "aging" NACA were a factor, Naim would be recommending we replace it as they suggest recapping our aging boxes.

Thanks for that valued contribution, Trickytree; most illuminating.
Steven/Dave; I agree that oxidation is likely to be the cause of the degradation in sound evidenced by a switch to the new stuff, but the cable ends are terminated and shrink wrapped in plasic - albeit not as well as the rest of the cable.
Two other points spring to mind - first, the plastic wrap will itself leach gas over time, which may affect its contents; and second, over time it will be porous ( at a microscopic level ) to air and so allow slow oxidation.
Whatever the reason, putting new NACA 5 into my system made a real improvement.

Mike -
I didn't think NACA 5 was around 10 years ago. Is it possible that you had NACA 4?

Mike,
Herm usually attends extremely tedious arty farty events on Sundays. He has appointed me as deputy spelling policeman:

That was my first thought - however, it seems that NACA 5 replaced 4 in 1989 ( product history from main site ) and I bought the kit in 1990.
As Mark says above, there really is a noticeable differance.

What's the price of NACA5 these days Mike?
Cheers,
Paul.

Paul
around £6 per meter; plus plugs, labour. So £50-£60 for the minimum 3.5 meter length, x 2.

Thanks Mike.Will need around an 8m pair,but can terminate myself.

Correct....I have an extreme soldering fetish!

Mike, Cardinal sin, I forgot the smiley

Some time ago my Naim dealer related a story to me, ( a very well respected figure, held in high regard on this forum ). It was sugested that he replace the plugs ( on a six pack, alot of plugs! ) as after time oxidation occurs and degrades the sound, this he duly did. The result? Shorter speaker leads, a lot fewer plugs in stock and no difference whatsoever.
This is not to say you did'nt find otherwise, but why imply that the cable itself has oxidised? If this were the case why not replace the cable inside the speakers, or even the amplifier? While were at it, remove every single item from the PCB and re-solder them!
There was a thread recently regarding differances between NAC32's and NAC62's in which Naim themselves admitted these amps could sound differant to each other due to differing suppliers of PCB's. I dont know if Naim have more than one supply of cable, but even if they dont, the cable manufacturer most certainly have more than one source of raw materials.
Every item Naim make is built to a tollerance limit. It is quite concevable that you bought a 'Friday afternoon' set of cables all those years ago, perhaps a few impurities in the copper, contamination in the sheathing, slightly differant plating on one of the plugs and even a dry solder joint thrown in for good measure. The gods have now provided you with as near perfect a pair of speaker cables as modern production meathods allow.
I think it more likley this is what you heard given the huge leap in sound quality. If the cables had degraded that much in 10 years, what would your system have sounded like another decade from now? Or perhaps the've always sounded that bad and you've only just noticed.

Note smiley this time please!!

I also wonder about an individual's soldering technique and how that could affect cable differences.

You may well be right... but from what my ears tell me, the new stuff really does sound better.
Simplest thing to do is pop down to your trusty dealer and ask for a new pair on loan.

I agree, it's very likely that the soldering technique and the solder have produced the biggest part of the difference. In my experience different solders can make identical cable/connectors sets sound *very* different. Any similar experiences guys?

Mike,
Of course there's always the (outside) possibility, that after the new cables are fully burned-in, in say 3 months time, they may sound just like your old ones
