Mj you can get all the advice you need from MIT rep. Joe Abrams, membername = joeabrams. He'll provide you with great advice & a great deal too. MIT makes a special line for Spectral but I don't see any of them in his present sale listing.

I'd suggest to go with at least MH750. He has one 8' pair & one 10' pair available. But for Spectral I think that I would suggest the Oracle series; he has an 8' pair of V4 for slightly more $ than the MH750. He also has a 10' pair of V3 Wideband EX, which would be great with your DMA amp if you can swing it.
You want cable made for solid state of course. Regarding impedance, that relates to interconnects not speaker cable. You need to know the input impedance of your amp, then go to their website to determine which impedance range matches it, or ask Joe. He's absolutely wonderful to deal with.
I'm using MH750 Magnum biwire with my big Accuphase amp & it does a really fine job.
