Power on popping sound


Hi Everyone!

Why does the left speaker always make a "pop" noise when the amp powers up?  Also, after preamp and amp are powered up there is a low buzz coming from the left speaker.  Not sure if I can hear the buzz from the right speaker.

The left speaker also makes a "whoosh" sound when powering off the amp.  

Getting paranoid about speaker damage.

Gear:
Speakers:                    Ologe 5 (Same thing happens with my LS 50 passives)
Amp:                            Forte Audio 1A 
Temporary preamp:     ADA Suite 8x8 - (I might pick up an Audible Illusion Modulus 2B but am open to suggestions.)
I also swapped in my Fostex HP A8 as a preamp and got the same popping and buzzing.
Rocket 88 speaker cables

Thanks!

Thanks for your help! I will try reversing the cables and also the LOFO steps.

Is the power supply capacitor an expensive thing to replace?
I reversed the cables.  Turns out it is the left channel. Thanks Yogiboy!

Checked out the amp repair site. I'll get in touch with them on the buzzing and pop sounds.  What a great resource!

@firstnot - What amp are you using with your Audible Illusions 3?

Is it better to use a tube amp with a tube preamp?
