Amp for Innersound Isis speakers


I recently purchased a used pair of Innersound Isis speakers and now need an amp that will make them sing.Thinking Sim Audio W-5 solid state or ARC vt100 tube. These amps(used) are maxing my budget.

Anyone heard this amp with Martin Logan Requests? I have a pair and am looking for jaw dropping sound. The closest I have heard to that is Clayton M70 monoblocks. The Bel Canto Evo is too sterile for these speakers.
If money is no object, perhaps the ESL amp is for you. For me, the PS Audio 200CX is the ticket, I have Acoustat Spectra 3300's. I am about to bi-amp them as the PS does run out of steam at VERY high SPL's. Perhaps I should just sit colser to them. :-)But for $500-$600 used, the PS Audio 200CX is hard to beat.
Thank you all for such informative and educated advise.Sounds like the InnerSound has found a home. Special thanks to Audiokinesis!
