How big is your listening area?

My medium size (2500 cu ft) HT is populated by M22V4s, QS8V4s, VP160V3 & a pair of magnificent EP800V3s all driven by a Denon AV Receiver (a couple of models down from the top of the line).

It easily drives all of this gear to levels that can become stupid. For most movies I set the MVL at -15 db/-10 db & music concert DVD/BDs at -20 Db. I have never experienced clipping nor audible distortion.

It might be wise to update your old Pioneer with something more modern...
