What interconnect cables, Which models to consider?
You could try Blue Circle BC95. BC's Gilbert Yeung is a Martin Logan fan and uses ML speakers as his reference.
I own ML Requests and Krell electronics. As many know this is hard to get right in the highs and cables are critical. I finally settled on the Pure Note brand. They are the smoothest (and most revealing) cables I have yet to hear.
You cannot go wrong with Harmonic Technology cables. Try either the Pro Silway or the Magic cable system. Dale
At the risk of incurring the rath of some I would recommend highly the hms grand finale. I put them into my system which is a bit different than yours in that the amp is an integrated tube/ss (nuvista) and was delighted with the outcome. There is a 30 day money back and tekunda is a real pleasure to deal with. He by the way uses the ML prodigy. If you want to look I wrote a review on AA (under moniker GG). I am happy to answer any questions you might have
