I've recently helped my brother put together a entry level system as follows:
Pro-Ject RPM 1.3 turntable, used NAD 3020e amp, Infinity Primus162 speakers
connecting wires are those that were packaged with the Pro-Ject turntable and cheap Monster speaker wire.
Sounds great, but there is a quiet, but audible hum. It can be heard as soon as the amp is turned on (prior to turning the turntable on).
Is this normal? Any help on what may be causing it (connections? maybe the age of the amp?)
In setting it up, we did zip tie the all the wires together. I think I remember reading something about not having the power conenction touching the speaker wire, but was unable to find anything.
Appreciate any help in advance.
