1) The NAD is a nice amp, but so were some of the Sansui offerings, though I am not familiar with the RZ-1000.
2) When does the "SNAP" sound occur? Is it when power is turned on? This could be a capacitor issue and may need to be looked at (I bought my 3020A new in 1979, i believe, so yours has a few years on it)
3) Any input except the phono will be fine to use with the CD, IPOD, or DVD. The Aux and Tape input were designed for line level voltage inputs as apposed to the very low voltage of the phono.
Great low power amp that has a smooth presentation. One of the units in my journey I regret letting get away.
