Ever notice the quality of RCAs on the backs of various receivers? Some of them suck because they are thin metal shells over plastic which are attached directly to a mother board with tiny soldered flanges. Maybe there is a screw holding the plastic casing to the back case of the unit. Then you can go to the opposite extreme where you have high quality, heavy all metal units with teflon internal insulation mounted bulk-head style directly to the outer casing of the product. In fact, even on expensive receivers you can end up with poor quality ones. I've seen good cables (tight connections) tear the cheap shell-type connector's metal parts right off the unit! This is one reason why I switched my RCA connectors on my cables to units with slightly less grip or two screw-tightening units. What I find interesting is that Denon will put out the 5308 which costs $3000+ and only use half decent heavier connectors in one position and the cheap ones elsewhere whereas H&K on their 8000 receiver use fairly decent ones for all RCA inputs/outputs. Most power amps have decent ones, but not all. Virtually all seperate prepros have better quality units than most receivers. Would it really kill the receiver mfg. to spend the extra on decent ones? IMO, having the poor quality ones is like having spring-clip speaker wire connectors.
