Try (active) Vertically Bi-Amping a pair of (sereies II or later) Sunfire Sig's to your speakers. OUTSTANDING!!! I have a pair of (series II) Sunfire Cinema Grands Sig's vertically (actively) powering a pair of old school Infinity IRS Beta speakers. I have one 3rd gen. Sunfire Sig. amp and I am waiting to get another, so I can use those to power the Betas and see how they sound compared to the set-up I have now. I also tried Bob's new (180 watts per ch.) Cherry 180 tube mono block Amps on these speakers (Tubes on the miss/tweets & one Sunfire Sig on the Bass), and they sounded pretty damn sweet; however, I tried the dual solid state set-up mention above and ended up liking all the extra power/headroom the Sunfires provided compared to the tubes.
I have yet to hear any of the Light Star equipment.
I have heard Mitcth4t's set-up (four Carver Silver9t amps w/ the O.G. Infinity Kappa 9's) and they too are to die for.
