Let's have this thread as an FYI on the anticipated new Spectral/MIT cables. As of this writing, the following info comes from MIT, and is really so fresh that even dealers may not be aware right now:
Speaker cables: Spectral has endorsed the Matrix HD 60 as the successor to the UL-770 Series II. This same product can be purchased from any Spectral dealer, as the UL60 Series III
Interconnects: The interconnects are still under the listening test (they passed all electronic tests) at Spectral, and we have not heard back from them at this time. The two recommended interconnects are the Matrix 36 and Matrix 50 as the likely successors for the 330ULII and 350ULII. All were designed and tested on Spectral gear, provided by Spectral.
