no quarter: I would be interesting to see what's really inside both those boxes..
I have repaired a ton of stuff over the years, one you get down to the circuit board I am lost, now in the most cases replacing them is pretty easy, but some thing tells me the power coming to your house is perfectly fine.. Now if your living in a house that's 100+ years old and it doesn't have a electrical make over, go for it!
A lot of other boxes will most likely do the same for less, or at least make claims they can.
Garmin, I'm not directing this at you, I'm just using you as an introduction to my post.
A good company will give you the option of the dry version or the wet version.:roll eyes: The dry version being fairy dust and the wet version being snake oil.
I'm just being facetious.
I think PS Audio makes a decent product. In saying that, I wouldn't get too hung up on power conditioning unless you live in a high-populated area with a lot of manufacturing. With a lot of population and manufacturing, you can get a lot of feedback into the grid and power fluctuations; then a good power conditioner will help.
Luckily, I live a rural area that is fed 100% by nuclear. We have no manufacturing where I live.
It doesn't matter what time of the year, whether we're heating or cooling or just have our windows open(spring/fall), I get a constant 123V +/- .1V at my receptacles.
When I remodeled the house, we rewired much of the old part and diverted that old wiring to a new electrical panel that serviced both the old and the new parts of the house.
100% of all residences in the US are 240 Volts coming into the panel. Two legs of 120 Volts each, which are 180º out of phase from each other. I instructed my electrician to make sure all appliances that had a motor or electronics (washing machine, refrigerator, dishwasher, microwave, etc.) were all on one leg. Just make sure my 3 dedicated circuits to my listening room are on the opposite phase.
I did 3 dedicated 30amp (10 Wire) circuits to my room. Other than isolating those circuits, the only thing I did was install really good receptacles. Grip!(surface area of contact). Electricity depends on good contact.
After the power cord leaves the receptacle (the last 6 feet or so), the only thing that matters is maybe some shielding?, and flexibility.
Cable companies are trying to defy the laws of physics, common sense, & profit margin.
