UPDATE: turns out NAIM only ties the neutral side to the ground in their source components - not at the amp.

Williewonka,
?? Your use of the word neutral is confusing....
From reading your posts I believe you use the word neutral in reference to the outer shell of the RCA jack, the signal ground.
Are you saying on your NAIM amp the signal ground is not connected to the chassis? The chassis is only connected to the safety equipment ground?
On the rear panel of the amp is there a signal ground lift switch by chance?
Lifting the ground makes the amp hum moreThat would make sense if the signal ground of the amp is not connected to the chassis.
