I have tried many speaker cables on my Soundlab U-1. Best results were from Nordost Quatra-fil , Purist Dominus, Cardas Golden Cross and top end Audioquest, such as Volcano.
All of these are extremely high quality construction, low capacitance and use high purity metals in their construction. The ones I listed are the high end of each manufacturers line, so if cost is an issue consider finding used.
My personal choices (in order) is Purist Dominus, Nordost Quatra-fil, then Cardas. The Quatra-fil is the most transparent, the Cardas is the warmest and the Purist is the most phase accurate and prettiest midrange.
Observations made on Soundlabs may not transfer to your Martin Logan's. For instance, the midrange on your Aerius may make the Nordost a poor choice. I would not be surprised if the Cardas was the best choice with your amp and speakers.
Please post results if you try some of these and what you decide.
