I was the first person outside of the MasterBuilt engineering team to have heard the effect of adding a single pair of Ultra interconnects in my system. I was at Axpona when the VSA VR100XS system was being displayed. During a break, one of the MB engineers arrived and asked Albert if he would audition a prototype pair of XLR cables that they (MB) had been working on. Albert said that he didn't have a balanced system set up at the moment. He then turned to me and asked if I would be willing to audition the cables for a few weeks and give my impressions. Talk about being in the right place at the right time.
At the time, I was using MasterBuilt Signature iC, SC, and powercords and was very satisfied with their performance. On returning from the show, I installed the ICs between my DAC and preamp. When I played the first piece of music, I was absolutely amazed at the transformation in the sound. The key attributes where this cable excelled were as follows.
There were additional fine details that present along with all the detail that I was hearing before. For example, during even the most dynamic piano recordings there was an additional "filigree" of complex textures in the piano's sound that made the reproduced piano sound much more realistic.
During quiet passages, the amount of information retrieved/retained in the signal was obviously much better. Hall ambience similarly took on more complexity, richness, and sense of a real acoustic space.
Oddly, even with such a major change in the system's quality, there was no skewing of the frequency balance, other than the bass being more extended to deeper regions and being more dynamic and harmonically complex.
Imaging, both laterally and front-to-back was improved along with that better defined recording venue acoustic signature recovery. Also, the sound height improved with the whole presentation being more immersive.
This occurred while my VR100XS system was being built. On hearing the dramatic improvement in the system's sound, I called Albert and asked if there was any way that Ultra cabling could be installed in my VR100 towers. It turns out that MB only had Ultra developed at that point for interconnects. I asked Albert to see what was possible with MB regarding Ultra speaker cabling possibilites. It turned out that it would take another year for MB to finalize Ultra speaker cables. During that development period we put the completion of my VR100's on hold, but now I have that first pair of speakers with internal Ultra wiring.
I also have a full loom of Ultra interconnects and speaker cables. I'm still using and continue to be very happy with a full set of MasterBuilt Signature power cords. I'll hear the Ultra powercords at Axpona in a couple of months. Once you hear the impact of the Ultra technology in a system, it's not easy to go without it. Back when I had to return those first pair of Ultra cables that I auditioned, it took months before I could get used to my system sans-Ultra.
Best,
