I agree with Rlwainwright-I would keep the NAD for now-which is a very good performer btw. IMO, NAD will sound better than the adcom. Your idea of upgrading the source and/or the phono stage is a good idea. I think you will get the most bang for your buck by upgrading your source. I would also look for used gear to save money. Your speakers are very nice, but can be a tad lean-perhaps a sub to get the bass pumping-that always helps to create more emotion in music and a lack of bass can seem a bit clinical at times?
