Audio is a funny thing as I had almost the opposite experience of BigKidz. I bought my Au24's upon a friend's recommendation, and after subsequent research. In my initial research, among other things, I found that some to many (including Stereophile) preferred the Au24 speaker cables over the Valhallas. So I gave them a try.
I went from AZ Satori shotgun dual run bi-wires to Harmonic Tech Pro 9 internal bi-wires to Au24 mono wire. The Satori's and Pro 9's were near identical sonically.
In my experience, the Au24's were far superior to either of my previous cables. And my desire to bi-wire subsided.
I found easily discernable improvement in the bass regions as the Au24's minimized/eliminated the time-smear in those regions. (Supposedly, this time smear is quite common in cables.) And the Au24's showed how grainy the previous cables were at the top end by providing enhanced detail with quieter background.
One caveat is that the Au24's appear to be amp dependent. Both in my experience and now in the experience of a few others who've contacted me.
I say amp dependent because with one amp the above improvements still occurred (but depending on what cables you're upgrading from of course), but the bass can give the appearance to kinda' become much lighter as it became much tighter.
But with another amp, the bass became outta' this world, rich, full, tighter than I've ever heard, and beautifully pronounced.
If you do notice a lightening in the bass while also noticing a tightening in the bass, I'd have to guess that the Au24's are bringing deficiencies of the amplifier to light.
BTW, it's also nice that the Au24's cost about the same as these other two.
-IMO
