power for mc452 and c2600


I'm relatively new to high end audio. Had a mcintosh integrated amp for few years and now decided to upgrade to separates. Just received c2600 preamp and awaiting on mc452 amp due to arrive sometime next week. 

I don't know anything about power conditioners and protection devices. currently using monster surge protector. My questions: 

1. what is the minimum protection device that one would use for my equipment
2. does it have to be a power conditioner or just surge protection
3. how much do these "power conditioners" contribute to the overall performance? Can you objectively measure their effect? Can they worsen the performance in any way by limiting power? 
4. is there a real difference in relatively affordable (200-500) vs. higher price units (1000 and above) ? 
5. What are you using and what is your experience with it? 
6. Your recommendation on units with good reputation under $500

thank you

Thank you pokey. I am touched. :)

So far we have not had our home flooded and water levels stayed stable in our area today. Forecast predicting end of heavy rain around midnight in the Katy/Richmond area.

Thank you again pokey, whart and Al. God bless you all.

Wish all the best to the folks in the affected areas. Electronics and water don't mix well, and those with the giant Krells, Boulders, Levinsons, etc., will have to leave them behind...(little humor in case not obvious)
Hi pokey,

We were very, very lucky. Flooding and mandatory evacuations all around us, but our home and property survived unscathed. Thank you for checking and thank you for your prayers. They worked! 

Dave
VERY VERY glad to hear that, Dave.

What a nightmare this must be for countless tens of thousands of less fortunate people, both now and very far into the future. It further reinforces how fortunate we all are to be able to enjoy quality music reproduction in the comfort of our homes.

All the best,
-- Al
