In my experience bi-wiring never improves the sound, it is always horses for courses, you win something and you lose something.
The initial feeling of an improved sound is often caused by a slightly better separation, but after a while I realise that the presentation have lost some coherence.
I gave up on bi-wiring long ago, and my amplifier manufacturer (Lavardin) bluntly advises against it.
With a limited budget having a better single wire speaker cable rather than a cheaper bi-wire one works fo me.
