What a great hobby! One guy does back flips over
something that yields little or no improvement for someone else!
I started with one Power Chip on a Furutech strip,
and really liked it. Adding another Chip to the
breaker box, and another to the cable from the main power box leading into the house, dramatically improved the sound.
I have not found that the Power Chips are very sensitive to placement changes. I have not experienced any break in period. Being in Maryland, where we can get 30+ days of 90 degree weather, I have simply turned the Chip "upside down"
on the outside cable (western exposure), so that it is somewhat shielded from the elements, and faces the ground. I have not noticed any difference in the sound under different weather conditions, like rain.
Then, there is the question, "What to add, or subtract?"
If you are adding a tweak that is making an improvement, is it worthwhile to subtract or take away other things that have been in place, and have been working well? Conversely, if you are adding something and not really experiencing a positive result, does it make sense to remove the tweaks that are already in place?
At least with friends or family members at a holiday gathering, you might have an idea of who mixes well with others. (And who doesn't!) In the audio world, an open
mind, and open ears, are your best allies... agreed?
