I've put my aged HK930 up against a NAD C320BEE and the HK wins, by a small margin. All I have done to the HK is have it cleaned and replace the preamp-out power-in jumpers with OCC cables. That's not to say the NAD is bad, in fact some people might prefer its more forward presentation. The HK is more laid back and with the new jumpers the timbres are sweeter. Probably I could tweak the NAD too.
The HK does need work. Its PS is aging and gets buzzy when the AC power is dirty. The balance and volume pots should probably be replaced, since at low volume (essential for the bedroom) one channel winks out. The NAD is utterly silent and plays at low volumes just fine.
If I spent the money to have the HK properly fixed up that would bring it pretty close to the cost of the NAD.
