I use a Carver 705TX with Jamo Concert 11 (4 ohm speakers). At normal volumes for me: Digital music through satelite (-25dB) CD's (-25), DVD-A (-30). If I crank it up to +5dB the amp starts to clip. At this volome level the measured loudness on my sound meter is 105dB to 110dB. More than enough for me.
