Power Conditioners Recommendations

I recently bought an Audience Adept Response for $311.00 used here on Agon and can not believe the improvement. I know it is just outside of your price range but read the reviews - they are accurate IMO.

The new PS Audio conditioners have received some good press.

Never tried them though.

I use a relatively inexpensive Monster strip for everything but the power amp and it does seem to clean and tighten things up.

I wouldn't use them, as Tvad said. If it is possible have dedicated circuit run to your equipment. If worried about storms, voltage spikes, etc get something like a BrickWall for $250.

I see that you are new, and looking for advice. Don't let people throw you-off with unhelpful and false advice....(roll of eyes)

Which unit you get may depend on where you're going to use it and with what equipment. Filters are useful for keeping noise pollution out of your system, as well as giving you the extra plugs you need without resorting to a cheap power bar. (which can cause even more noise!)
Cheaper noise filters can be a problem when you have a big amp that draws a lot of power when it gets loud. Unless you have a really good filter that can handle the current without strangling your amp, plug the amp into the wall and everything else into the filter.

I happen to have two of those units right now. I wouldn't use them in my expensive high res Audio system, but they do have a place in my Home Theatre. The Adcom ACE 515 was the first filter I ever bought, and it does a decent job. A couple of years ago, I upgraded to the Monster 3600MkII for my main rack of equipment at the side of the room, where it does a fine job, and moved the Adcom over to where my TV and subwoofer are.
The TV looks noticeably better when used on the filter, and the subwoofer gets plenty of clean power. Everything else is plugged into the Monster, except the seven channel amp, which can draw a lot of power.

There are other options of course, but if budget is a problem you can't really go wrong with the ones you're looking-at.

When I look at my Monster, I kinda' pause and think about it, given their stupid pursuit to OWN the word "Monster" and their legal harassment of other companies that use it. I'm not buying Monster anymore, but I had this unit before that story really hit the news Big Time, and I'm not going to sell it just because of that. Just remember that there are a lot of people who bad mouth Monster because of this, or just because they mindlessly parrot the same propaganda because they heard it somewhere else. It is your decision to make and all that crap doesn't change the fact that the 3600 mkII does a good job...so buy a used one and be happy!
