Let's discuss power source!

Miguel,

What changes happened ?

Kelvin can answer all this, but unfortunately, by now, I think he's dead.

However, his observations are still with us.

Believe it or not, Kelvin currents, expanded upon by Kirchoff, started out very much like Newton's laws did after the apple hit him on the head. In the case of Kelvin, he was making his living in telling folk where the silt was in canals so they knew where to dredge.

We now know that the silt builds up on the side from where the wind predominantly blows.

What has all that to do with audio you may ask?

Well, substitute current direction for wind direction (a westerly blows to the east...) and find the source of the current, and that's where it flows back to - just like the currents in the water which deposited the silt right back to the side where it started. Made Kelvin a few bucks!

Today, we see terms like "Kelvin capacitor" when reading about amp decoupling - or should I say, we read about such things in the real world, which unfortunately most of you guys don't usually see because of all the hi-fi hype - but then again you have me...

So, if the power starts out at the power station... yup! It ends up back there on the other phase!

So, I guess you could take that as an add for batteries? Nope! Unfortunately batteries often let the side down because of a thing called internal resistance. But, if you use a truck battery, that can be minimised.

Now, because all this stuff is part of the basic knowledge required to build incredibly good sounding gear, then I do actually take it into consideration. In fact, it's a major consideration.

But, at some point I have to say "No, that's it! Nobody will pay me what it takes to go that far". It is a case of diminishing returns - the cost curve increases considerably whilst the perceivable improvements become fewer.

I don't want to put the dampers on this discussion - in fact, I want to encourage it. But let's not confuse differences with improvements. Often there can be a big difference, but it may not be an actual improvement when heard by others.

This place is a credible place - let's keep it that way for our visitors.

Due to the ferrites on both ends I felt the music presentation was clearer and the background was blacker. Also the cable is shielded and since I have a very crowded cabinet with a lot of gear I believe it helped in the overall sound presentation. Lastly I purchased the power cord on sale fro under $90 USD so I do not have a lot of money sunk into it. YMMV.

I have replaced almost of my stock mains cables and heard a difference in most cases. the cables vary from £50/60 to £150. Two big impacts: the CD player (clearer) and subwoofer (faster and punchier on kick drums).
