OK, I've rechecked mine with the house silent.

There is an extremely low level of hiss. No hum at all. As described by others, this is only audible with my head RIGHT AGAINST the grill cloth. It is as low as the level of hiss I get from my Norh preamp, which is virtually none.

If I had my TV on, the noise from it would be far more noticeable (flyback transformer whine, etc.).

So, either something in your environment/system is affectinng your 950, or there is a problem with your unit, or their manufacturing parameters are unacceptably variant.

hmmmmmm.
