Of course we encourage you to voice your opinion on our forum too. Some may fear that adding an external amp will in a sense " waste " the unused internal amplifiers of the AV Receiver. Our answer to that is to simply reroute them. Most modern AV Receivers allow you to reroute them to power speakers in another zone or to add height channels to do a full 9.
Another option would be to power a second set of speakers in another room from the main zone if your receiver doesn't have multi-zone capabilities. You can turn them off by toggling the main speaker A or B switch. Fear not as there is always a use for those unused amplifier channels.

Some manufacturers such as Naim and Cyrus have dedicated connections for adding external power supplies. If an integrated amplifier has pre-amp outputs, then using it solely as a pre-amp and passing amplification duties onto another amp, is another great way to upgrade. Whatever the rest of your hi-fi system and your future plan for it, introducing a new stereo amplifier requires some thought and a bit of advanced planning.
