According to the factory, NACA5 would have the 3.15 uH inductance @ 3.5 m to protect the amp and only 56pF capacitance to upset it.I don't have the figures for the RS cables, but my guess is not a good thing for your amp.
Naim amp would be happiest with 5 m (= 16.5') NACA5, providing 4.5 uH inductance while confronting it with only 80 pF capacitance.
In reality, this formula isn't set in stone, ( speakers/loudness matters, also ), however, I won't be taking chances especially older amps, for sure.
Think before you keep using your RS cables on your beloved Nait 2 as NANA does not offer to fix them any longer.
Follow Ups:
Naim recommends the cable, which may not mean a lot to some, but the cable is designed to be used with Naim amps. It is not that expensive and you can find appropriate lengths available on audiogon from time to time. I think the minimum is about 4 metres but a lot of people recommend 5 metres. Also the input cables should be of a high quality. Chord make some din/rca adaptors that work well.The 2 is a very desirable integrated among the Naimees. I have both a 1 and 2. Both are great, altho limited in terms of speaker choice.
In the old days it was suggested to leave the amp on all the time to avoid the turn on/off thumps, but as the amp is old, I have been turning it off when not using it.
Well okay then....thanks, that's exactly the info I needed! I'm really enjoying the sound of this amp. I've tried alot of mid-fi and budget gear (I'm broke, and cheap on top of that), and it's currently running in place of a Luxman R117 160 wpc receiver. A nice unit to be sure, but the Naim is holding it's own and actually giving a little more performance in the midrange. I'm driving KEF 103.2's, I think I mentioned, and it seems to be controlling the bass well (closed cab with an 8" woofer). I'll keep an eye out on ebay and audiogon for the NACA 5. Again, thanks for the advice-David
till you get a NACA 5. ( remember you need minimum 3.5 meter ).The first sign of distress of amp: touch the amp and if it's too warm or getting warm, your amp might be experiencing a thermal runaway...
