bi-amping Dunlavy IV speakers


I recently bought some tube amps--EAR 509's---and sold my Krell KSA 200s. The new EAR's are gorgeous up top and mids but lack the weight, authority, and tautness of the Krell bass.

The Dunlavy's are bi-ampable but there's nothing in the owner's manual about this. Anybody have any experience bi-amping Dunlvay IV's??

Could someone please tell me which binding posts on the Dunlavy's are for the highs and which are for the lows? They are not labelled. I am assuming the top pair are the highs and the bottom pair the lows, but I would like to know for sure.
Thanks.
Hi,
I just forced myself to purchase the Dunlavy Aletha which are also bi-wire-able (Upgrading from Nautilus 805). I use Krell KSA250, KSP-7B, and Cardas Quadlink speaker cables. I am thinking to upgrading the cables since I want to get a more "open" vocals. If I have a very limited budget (as I have spent over-budget for the alethas), is it better to upgrade to better cables (but non-bi-wire) or get another similar cables to bi-wire them? Which cables is good to get a more open/ dynamic vocals? Thanks
