NAD 3020A Integrated Amp

So I have a series of questions re: a NAD 3020A I just bought on Ebay. I'm just getting started on trying to build a good system so please excuse my lack of knowledge.

1. NAD 3020A Amp hooked to JBL 4312A Control Monitors and new REGA RP-1 Turntable. NAD is replacing a early 90's Sansui RZ-1000. I would have thought there would have been an appreciable difference in sound quality but I'm not sure that there is. Can't tell if it better, worse or just different.

2. NAD delivers a electrical snap sound to the speaker which Sansui did not. Is this cause for concern? Should I have this unit tested / looked over?

3. As this is an older amp it has limited inputs. Is it ok to run IPOD or DVD into the AUX input? Also no CD input, any ideas?

Iamnate, most likely not all caps need replacing, just all the electrolytics. Unless you can get a copy of a service manual to identify their location and values and have some de-soldering and soldering skills, you will be advised to find a tech to do this. The labor will be much more than the parts cost.

I have a 3020A I use in with my TV. I replaced the speaker spring clips with mini-binding posts and that is also recommended.

Iamnate, specifically to your question about using an outboard amp.

Basic question, how sensitive are your JBL speakers? Does the NAD under power them or are you wondering about a better quality amp section?

I've only used mine as a full integrated (and Nmmusicman's suggestion is likely a good one) but years ago there was an audio topic program on a LA FM station called "In Fidelity". The guy who hosted that used the preamp section of a 3020 with a Dyna St 70 to drive his Quad 57 speakers. Considering how revealing the Quads are it must have had good sonic qualities. Note here I'm not suggesting the St 70 for your situation. That would be a different question.
