Electricity. We don't fret about it unless there's a blackout or a lightning storm. But it's constantly humming away feeding our HDTVs and A/V receivers.

The problem is, electricity does not always flow consistently or cleanly. It spikes in intensity. And when it's feeling really mischievous, it will start looping through your system causing all sorts of problems like noise in your TV picture and buzzing in your audio.

A good surge protector – I assume we all have one – will safeguard your equipment from catastrophic lightning strikes. But to clean up the common everyday electrical current annoyances, you need a power filtration system.

Manufacturers like Panamax offer filtration solutions at prices starting under $100. With a suggested retail price of two grand minus a nickel, the MAX 7500-PRO is at the top end of their power filtration system line.

At 36 pounds, the MAX 7500-PRO weighs as much as a 32" HDTV. Just by lifting this solidly constructed black metal box, (17" W x 12.75" D x 3.5" H), I knew I was holding a serious piece of equipment.

I'm not an electrical engineer, so I will not delve into the MAX 7500-PRO's specifications. (You can find those on the Panamax website.) Though, I do like this impressive photo of the guts of the MAX 7500-PRO. That blue Isolation Toroidal Transformer is one of the main components that keeps that unruly electricity in line.

On the outside, I appreciate the elegant curved design and those glowing blue lights. But the real coolness are the two round, auto dimming meters with their analog display and actual moving arms.

On the back are ten outlets, (2 Always On, 6 Switched, and 2 High Current), where you plug in all your home theater equipment. An extra convenience outlet is included on the front.

For protection and filtration, you can also loop through your cable and satellite coaxial sources, and your telephone and Ethernet lines.

Setting up the MAX 7500-PRO is a simple matter of plugging your gear's power cords into the appropriate outlets on the back of the box. Four of the outlets are Filtered Regulated, four more are Isolated (Switched), and two are High Current.

The manual does a good job of explaining the different outlet types. And more importantly, they instruct you on which components, like DVD players and subwoofers, should be plugged into which outlet.

As a nice touch, Panamax includes a goosenecked convenience lamp, (powered from a USB jack) for illumination in tight dark spots.

Even if you have cable TV, phone and Ethernet lines to connect, the whole process shouldn't take much more than ten minutes – unless you have a hard time untangling all your cords.

I didn't test the MAX 7500-PRO with any fancy electronics equipment so I can't scientifically tell you how well it performs. My judgement is based on what I saw and heard while watching HD content like the Blu-ray DVD of Dave Matthews and Tim Reynolds performing Live at Radio City

I will say that I thought the picture on the ViewSonic that we have in for review looked cleaner than without the MAX 7500-PRO. I also noticed that our subwoofer wasn't popping as it occasionally does.

At $2000, the Panamax MAX 7500-PRO is not one of those idle "oh, you might as well throw that in, too" purchases. But if you are trying to squeeze every ounce of performance out of your ten – or one hundred – thousand dollars worth of home theater equipment, then you seriously need to consider the MAX 7500-PRO to filter your power.
