Power Strip Sound Differences.


My system is a Denon modded universal player, a Luminous Axiom passive preamp as my volume control, two B&K Sonata M200 mono amps, and Silverline Sonata 2 speakers.

I installed a new Hubbell cyro wall outlet. The outlet is not connected to a dedicated line; however it is the first outlet in the line, with only two lights being used further down the line.

I plugged a three outlet (six plug) power strip , built with the same Hubbell outlets, into the new wall outlet. I plugged the two B&K amps into the front two outlets on the power strip and plugged my Denon player into the remaining wall outlet.

What I noticed was way more bass than I had ever experienced before in my system; however with a loss of detail and space in the overall music. I then, after a couple of days, moved the Denon plug to the rear of the power strip behind the two amplifiers. This arrangement gave me back my detail and space with a more balanced sounding bass.

I knew Ac outlets and power cords could make a difference, but I had no idea that where the power is located in the path of the individual components could make such a big difference.

I really like the way my system sounds now; however I am always looking to improve. I was wondering if someone out there has had experience with setting up their own equipment with power strips and maybe can tell me if there is a better way with only one wall outlet available for my system.

take a look at the Balanced Power Technologies site.

I just took delivery on one of his plain vanilla PPC - pure power strip

I also have a CPC.

These two are his bottom of the line but they both work very well

I would go so far as to guess that the position on the strip would not make a difference with these products

Hi Kevine -

A lot of the better power products (BPT, Equi=Tech IMHO) provide isolation between each duplex. Depends on the mfg - some designate specific duplexes for digital, high current etc - but at least with the isolated duplex engineering approach you create an effective barrier to a good part if not all of the digital grunge.
