I have been able to recently compare the Venustus against the Aqueous.
The Venustus has defintaly more bass but not tighter bass.
The Aqueous has more high end extension and better overall dynamics.
Ozzy, a bit more info please. Were the cables tested between your 3910 and Pass? How would you characterize the basic sound of both the APL and the Legacy? (I already know what the Pass sounds like.) I have heard many good things about the Aqueous, but I am still using the Venustas between by preamp and amp. The rest of my system is AZ Silver Ref II, so I'm wondering if I'm getting a similar "synergy" effect, and maybe using the Aqueous would be too much?
