What Cables to Use on Hegel H200-H300 Integrated

Picked up a Hegel H200 and presently using MIT AVTs1 biwire cables to my B&W 803s speakers. Will be picking up my Oppo 105D next week and plan on acquiring an Ayre C-5xeMP soon as well. Wondering if I should stick with the MIT cables, or try something different at this point? Any insight from actual Hegel owners would be especially appreciated.
Whats wrong with AVTs 1? I use a 20 ft pair on Maggies and am well pleased. As good or better than CVT's which were next step up.
The Best cables to use are always the cable you like the best.
I use Nordost Blue Heaven. But I also use Blue Heaven for my speakers.
