Nordost Vahalla or Mit Oracle

I would update the digital front end before spending $5K on speaker cables.

That is your weak link IMO.

Wire technology does not change appreciably from year to year as the manufacturers may have you believe.

Digital does.

Well I have made the mistake of auditioning the the Kharma enigma (biwire version) in the system, and all I can say is holy ****!! I'm hooked. The room just got wider and a lot deeper. Lows are swift and authoritive mids and highs are more open and airy. The only drawback is they are about three times what I wanted to spend, but with this kind of sonic reward who cares!

To be honest I think there are better speaker cables then Nordost. I will admit the Nordost cable I have used is not in the same league as the Vahalla. I think Nordost speaker cable is not really neutral I get a feeling it gives a false sence a being highly detailed. To me the mid seems a tad more present wich as result gives the idea of a highly detailed cable.
If I were you I would look at and try out other brands as well, brands like JPS lab and NBS.

I may be biased but when I switched from a Nordost to NBS speaker cable, I got less of a hifi sound but more music. The music had the same amount of details. But is justhad a better flow. With the Nordost I was listening to details and with the NBS I lsiten to the music.

I wish I was better in explaining what I hear.
