First think TVAD could have point on the amp being issue.Cables are right ones to soften things up (sold Krell so needed to tell friends who bough Krell even though boss went elsewhere).Fact is you have one of my favorite speakers because I am someone who think gear is waaay overpriced new and used.
I'd say from your list the Dali's are a must.I sold a few lines years back (B&W,KEF and couple non-Brits).Of your list not familiar with Vienna enough (passed at show).PSB are bang for buck but I would go elsewhere myself.Sonus's are a hit or miss speaker in line.You might be a Maggie person if you have space.I don't like them and listen a lot at Friends who has classic 3.6/Bryston 4B ST I got him (he had III's before).Above mentioned Von Schweikerts aren't bad choice.I'd add maybe Spendor.Or used pair of B&W 803N/S.Audio Physic if you use them on long wall (the way they disperse).But I think Totem is damn hard to beat in terms of value though I'd check Usher line used.By ignoring patents and assembling in Taiwan they have big bang for buck.If you were going for new amp and it was low powered SS (pass),Class T (Redwine)or low tubes Silveline has great sound that is highly sensitive.But from your list think Dali is worth the hunt and Usher is you can find.
