NAP500 - which I require myself for this

Posted by: Ulrich Hohn on 16 September 2000

I live in a renting house and cannot play not loud. In contrast to
a NBL my SBL is a light load, so that the amplifier became
warmer in the 6 weeks never than 35 degrees Celsius.
My Nap500 does not play yet as well as the Nap500 at the
home-demo - although this was only 4 hours with me at home.

I require myself a cooled resistance, which I can attach at the
amplifier and which is loadable 2*25 Watt. Do I ask the impossible
from Naim?

At the home demo 5 months ago I heard sounding harpsichord music for the first
time on a hifi system well. I thought after this demo really that my
Supercap/Snaxo 4*Nap135 is defective.

Of it my NAP500 is still far. If it is run-in in 4 weeks not yet,
I give it to my dealer for 2 weeks. In the cellar my dealers can play
very loud with a NBL.

I believe that Ulrich is enquiring about the possibility of using a 'dummy load'- essentially a heatsunk resistor- to drive his new 500 into in hopes that this will allow the 500 to break in quicker than the SBLs.
While this may be a way to quickly (and silently) break in certain non-naim brands of speaker cables, I am not sure that the 500 would respond to such treatment. It after all has been powered up for the last 4 weeks, during which time a lot of music had to have been played, even at neighbour-friendly levels. I think that the setup should be carefully examined. Cable dressing, equipment siting and support and the solder joint integrity on the NACA5. No doubt that there was some rearrangement during going from the snaxo/supercap/4x135 to the 500. A job for the dealer-installer methinks.

Ron, thank you for your reply. The NAP500 is powered up for more than 6 weeks (every minute round-the-clock
with music from a NAT01 or LP12). The setup is carefully examined by my dealer.

I would not like that one misunderstands me: My NAP500 sounds better than every other to me well-known amplifier.
It is only the long run-in time which disturbs me. In all other respects I think that my SBLs still already
best to sounding passive SBLs belongs.
