Amp cutting out/shutting off at same place on CD

I have had a Sim Audio W-5 for about 1 1/2 years now and use it with a Sim Audio P-3, Pioneer CD changer and an MSB Link DAC III. I've been very pleased with the results using Soliloquy 5.3 speakers. Over the holidays, I hooked up a pair of James 10 Loudspeakers to give them a listen. I liked the result with them as well but when I got to track 6 of "The Big Picture", a Telarc CD of Erich Kunzel and the Cincinnati Pops Orchestra the amp just shut off or cut out part way through. The track is one of the Apollo 13 Mission and is pretty intense. I tried it several times and at volume levels over 50% the amp cuts out every time. At 50% or less it plays all the way through. Do I need more power or is this normal? Has anyone out there had the same experience with this particular CD? Is the amp protecting itself by cutting out or is the CD overloading it or what?

Depending on the drive level from the source, the dynamics of the recording and the overall gain characteristics of the amplificiation chain, most systems are running at or very near rated power with the volume control at appr 1:00 or 60% of wide open. With that in mind, your guess and Kelly's response is right on the money. You need more "juice" in order to maintain the listening level that you're trying to achieve and your amp is protecting itself. Sean
