A question for all of those electronic gurus.

How come when you have speakers with Bi-Wire connections using Bi-Wire cables makes all of the difference ?

An example:

You have 4 connections on the back of your amp, 2 red, 2 black and on each speaker you have 4 connections, 2 red, 2 black.

If you use 2 sets of cables with 1 black and 1 red on either end and connect both cables at one end together to enable connection to the above amp and then leave the other 2 cables free to connect to the speakers.

A mate of mine and I tried this on his new speakers and it made such a difference over using single wired cables going into the speakers with spliters on speaker.

Difference in the sound:

Large soundstage, sweeter treble, no muffling, tighter bass, cleaner sound.

Any help to understand this one would be appreciated as I am a little lost

Thanks

Paul.
