Fluctuations of the loudness of speakers???

I've just discovered something that has me concerned. Sometimes while listening to music, either of my two speakers (that are probably not broken in yet)suddenly loses volume (not all the way but still very noticable)...it's like they lose juice suddenly. It's more noticable at lower volumes but happens at higher regardless. I don't know if to blame speakers, or cables, or if my power outlet has a problem with my 250 wpc amplifier. Sometimes a simultaneous "crackling" sound occurs. I have no idea if the problems are related but at keeps me up at night :-( Any ideas greatly appreciated...

Recheck your cables...(interconnects and speaker) - make sure they are clean and tight.

Most problems with electronics involve connections. I would clean all connections (the Caig A/V Survival Kit does the job well). Then treat all connections with Mapleshade SilClear or similar. That may solve your problem. If not, you may have a bad interconnect. Try changing them out one at a time to eliminate the bad cable. Beyond that, you may have a bad tube, (if that applies) or something else internal in amp/preamp.

Cables are all brand new but the tube does apply since I have Musical Fidelity Nu Vista amplifier that supposedly contains some tubes. I wouldn't even know how to go about getting let alone replacing one...

Do you guys think a bad tube would probably be responsible for the volume fluctuations rather than an occasional "crackling" sound? With rock music hard to notice, but put on some ambient music, and it's more noticable...thanks everybody for their (even future) inputs and ideas.
