Good speaker match for Sim Audio W5

Can I please get some Sim owners to give me some ideas before I start on the 'fun' speaker audition track. Just want to get some feedback and perhaps narrow my choices down a bit. I am looking for mostly excellent transparancy and good bass and the infamous 'speaker dissappearing act'(not sure if thats not more of a room and placement issue).

My supporting equip
Wadia 830 CDP
Golden Cross Cabling thru out

Thanks in adance!
