There are differing camps on this subject; mine is that one should utilize separate amplifier(s). I have three reasons for this.

First, it allows upgrading either the preamp/processor or amplifier(s) without changing the other. This is pretty important considering that format revisions and technology can obsolete a processor. Second, the power supplies in even large receivers do not match those in the better amplifiers. Receiver space availability usually limits the size of a transformer and capacitors, and switching power supplies have limitations. Finally, receiver amp output impedance is normally relatively high, resulting in a damping factor usually no greater than a hundred or so.

Select nice sounding amplifier(s) having a damping factor no less than 400 for excellent control of drivers handling mid-bass and/or bass. Personally, I like sonic performance of the large Rotel amps, but would not consider a Parasound amp; a subjective opinion.

If you would rather not invest in a great preamp/processor, then consider obtaining a moderately priced receiver for using the preamp-outs to your amp(s). The better Yamaha receivers have good preamps, but some others do also. Regardless of the preamp (or receiver) manufacturer, ensure that you choose a model having a phono amp stage and, if possible, Pro Logic 2 processing. The latter is an improvement over the original Pro Logic.

Well, that is one view; there are several others. Good luck.
