I too believe that Sig600 (havent heard the Lightstar) could be the end point and could go with any high performance speaker at any price paid.
I did lots of vs. vs. of modern D class Wyred4Sound, NuVista, Krell KAV400i, Bryston monos and found that sig600 has sonic advantages over models listed plus is affordable. It works its best in the balanced mode.
