My Yamaha clips at 3/4 volume


I have a Yamaha M-45 and Aragon 28K preamp driving a pair of A/D/S L810 speakers. The problem is that the amp clips at 3/4 volume and a couple of times the preamp turned off. Does it sound like there's an issue with the preamp or the amp. When the clipping or whatever it may be happens the speakers have virtually no detectable distortion which leads me to believe that isn't the problem.
Do I just need more power for the L810's to satisfy my need for volume?
Thanks for any responses

Mrdecibel,
I turned up the output levels to full and voila...I was recomended by a friend to keep them at 1/2 output (don't know why) but since putting them at full output what a definite difference in output(WOW!). I have more than enough volume and it doesn't go into protection mode.
Thanks to everyone of you who responded!
You guys rock and now so do I.
I'm using a Technics SL-PD867 CD player along with the amp and pre-amp. I had the volume pot on the preamp at about 2 o'clock, the left and right output levels on the amp were at 12 o'clock. I just got the M-45 and Aragon 28k, previous to this setup I was using a Yamaha A-700. I'll get it back to make a comparison.
When I checked to see if the Class A switch was activated, it wasn't. What I discovered was that both the A and B switches were both activated and the speakers are only connected to A. Could this have an effect?

Thank you Elizabeth, Rrog and Sandstone for your help.
As you can probably tell I'm somewhat of a novice when it comes to stereo equipment.
