    Where is the distortion coming from?

    I've been dealing with intermittent distortion coming from my setup for a while. The core of my system is a Realistic Lab-250 turntable going through an NAD 3020b. I'm currently using a pair of Klipsch Fortes, but it's happened with other speakers as well. The NAD was thoroughly restored earlier...

    Hi There

    Just taking a sec to introduce myself- I’m a NAD 3020 enthusiast (and its siblings and cousins) and collect and nurse silver versions of the family. I hope I can contribute some knowledge here and there and I certainly have plenty of questions. Photo of my current rig attached. Cheers.

    Did adding a speaker selector screw up my system?

    I've got two pairs of speakers: a pair of Original Large Advents, and a pair of EPI T/E 100s. I picked up an Adcom GFS-3 speaker selector so that I can A/B between the two, and hooked it up this evening. I'm using a NAD 3020b as a pre-amp and an Exposure 2010s power amplifier. Originally, each...

    Upgrade from NAD 3020i

    I have used a NAD 3020i as my amp the latest 10 years. I have not found any amp that can match its details and treble. Though, since trying a NAD 319 dedicated power amp in my system I realise that the 3020i lacks definition and power in the lower frequencies. I wonder if anyone has a...

One channel is slightly louder than the other one, so do I need to do the bias setting as described in here or do I have another problem? I already have replaced all caps. Is there a service manual for the...

    Choosing amplifier to suit speakers. NAD or Pioneer?

    Hi. My amplifier, which i think is the weakest part of my system, is giving me problems which are making me think I might be better off replacing it than repairing it. There are currently both a NAD 3020, and a Pioneer A400 for sale nearby, both of which seem to be very well regarded. I've read...
