Do I need a power conditioner?

I'm not about to say I know more than you but wanted to add the comment that if you read the stereophile forum comments posted by randy-11 you will notice that the poster raging against balanced power is saying that it is against NEC to have a balanced "circuit" which I'm sure is true. A balanced power "conditioner" (device) is different than a home "circuit". I use a BPT 2.5 Signature and the instructions say to use it with three pronged plugs. It is certainly not intended to be used on a lamp or other two pronged device. Does anyone really believe there would be so many balanced power devices available on the market if they weren't UL approved? I get a kick out of electricians and their absolute disdain for audio enthusiasts (I'll avoid that term that carries so much baggage). 

Re concerns about installing balanced circuits. It can be done within code but the outlets must be clearly labeled as non standard outlets. I had an Equitech wall mounted balanced transformer in my previous installation and while I thought it worked well the complexity of the system and problems in selling the house (I needed to rip it all out on selling as the buyer wouldn't touch something this outre) mean I'll never go that far again. My current solution is based on a Torus wall mount that has balanced input but standard outputs which I think gives you the best of both worlds 

Lots of good advice. I am also a fan of balanced power.
Like others I have tried various conditioners over the years, same
conclusion as others to many trade offs. Last year I saw all the buzz
with HFC's MC-05 plug in conditioner, tried one, wound up buying 4 more, absolutely no trade offs crazy part is they are not even directly in the power chain, huge bang for the buck.  

So the Equitech 2RQ arrived yesterday.
The more I read about it, the more I am convinced that balanced power is the better solution for eliminating noise in theory. In practice however, no way to know till you actually hear the results. Of course you can look at the list of heavy hitters that use Equitech. Never the less, I was apprehensive till I got the unit plugged in.
Started out with my Oppo 95 to PrimaLuna Dialogue HP Integrated to Zu Druid. (high sensitivity speakers more revealing, including noise, I think.)
Put it there cause the thing is freakin heavy, and I didn’t have any help to lift it into the rack on my real system. Long story short, I already ordered another Equitech (Son of Q jr this time) because I can’t imagine listening to that system again without the Equitech.
I feel kind of silly trying to give a subjective impression. All the audiophile terminology sounds pompous and pretentious coming from me cause I’m kind of a newb. But it was apparent right away that this thing is a game changer. Made orders of magnitude bigger difference that all the previous tweeks I’ve laid on that system, and there have been plenty. So yeah, drop the noise floor like that and you are gonna liberate the actual music that has been hidden behind the layers of smear you have been previously hearing. Pretty damn happy about that.
Seems to me that all the filtering that other conditioners use remove some of the music along with the noise. The better ones just have a better noise to music removal ratio. Pretty sure the Equitech just removes just the noise while leaving the music intact.
Glad I came to Audiogon forum again. You guys turned me on to a product I knew nothing about, that seems to be a much better solution than what I previously had in mind.

@leotis,
The first time I heard my Equi=Tech 2Q in my system (years ago, 2001)
I described the music as sounding like it was on steriods, in a good way!
