I have inherited my father's Naim Tri-amp system. This is a very early one with the Isobariks serial numbers 13 &14.
I have the following items,
NAC 32
NAXO
SNAPS (2 off)
NAP 250 (3 off)
All are original bolt down, the 250s were serviced about 10 - 15 years ago. The other items are untouched. The there is hum on the MC input, this is present with turntable unplugged. There is also a faint burbling in the background present with and without the preamp. (Need to eliminate the WiFi router as a possible cause.)
I also have an olive NAC62.
My questions:
32 or 62 as preamp?
Is there a sensible way to use the second SNAPS?
Any advantage in dual railing the preamp?
What regulator upgrades options for the SNAPS?
Anyone tried the Witch Hat upgrade on the 250?
