Amp protection circuitry? all that its cracked up to be?

I was curious what everyone plugs their amps into? The wall? A surge suppressor? Power conditioner? I've been on the listening end of a Bryston 4B-ST amp for some time now, just recently upgraded the home theater to a Proceed AMP5. Both user manuals claim that the amps have internal protection circuits and RF rejectors and they should be plugged directly into the wall socket. Does anyone believe this? I've noticed quite a difference when I plug my 4B-ST into my MonsterPower HTS3500 as opposed to the wall socket. The sound gets sweeter, and the imaging improoves. Can't say if the power drops off as my speakers are fairly efficient and I'm nowhere near to straining the amp. Just curious what everyone else does. To be honest, the main reason I plug into the HTS3500 is to make myself feel better about a lightning strike. Granted, if lightning hits on or near the house it's probably all over. I knew this guy who's house got hit by lightning. He lost power, and it would not come back on. Finally, he called the power company out. They were amazed to find that every single wire in his walls had vaporized! They said he was darn lucky the house didn't burn down. Anyway, I ramble...

Protection from what?
It used to be that the 'amp protection circuit' was to protect the speakers, That went out of vogue in the High-end, mid 80's time frame.
Protection from Lightning: forget about it. there is not enough known about lighning to adequatly protect equipment from it.
Recently there has been a plethora of products that advertise "cleaning" and protection for audio equip. some works, some doesn't, what do you hear?

I doubt that we can protect our equipment from a direct hit and if you were that unfortunate, I bet you'll have bigger problems to deal with than your HiFi. ;-) But there are times when near by lightning strikes can cause spikes and power surges on the AC line. I feel safer having my gear plugged into a high quality surge protector. If I'm home and notice lightning strikes around my immediate neighborhood, I unplug my all gear by unplugging the Monster Power HTS5000.

I talked to customer service at Madrigal, and they said to plug the amp into the wall and then the surge suppressor and use whatever sounded better. They recommended that the best solution would be to plug the amp into the wall and get a dedicated AC line. They said the amp has 6 protection devices, and if a surge blew through that then it would probably make it through the HTS3500 as well. I may just plug the thing into the wall and be done with it.

Lightning storms are very problematic for me as I have to really turn the volume up to drown it out knowing that if I get hit my insurance will pick up the new gear...... Lightning is a strange thing and best way to prepare is to get your insurance agent to go over the options and make sure you have adequate insurance.....Plug the amps in the wall and line level gear into a good AC filter....
