Hi-Fi, I find your observations the opposite of mine except for the warm part. I just purchased a pair of 770 Reference 2 tube cables and found an improvement on image focus and air, soundstaging, timbre accuracy and BASS definition (that's right) and the highs were more relaxed and natural without any loss of detail. I am at a loss as to the differences we hear but every cable I have tried up till now sounded too bright on top. I am now absolutely delighted with the sound and rate this upgrade among the 2 best in my system over the past year. It must be system matching. Maybe the differences in our systems?
