The AQ Water cables are going to be much more laid back than either the Niagaras, and probably even more laid back than the Kimbers.
I've had the Kimber Silver Streak and the Niagaras here. I found them both aggressive, and forward compared to the AQ Colorado and AQ Sky cables. (which I still have and like)
The Waters are the warmest, most laid back AQ I have tried. What your hearing is the same thing I heard with them.
