3/9/2017 Rose Aurora Update
STILL CERTIFIED BASSHEAD. My XB90ex has been resting.
I've purchased a $12 silver plated copper cable from Aliexpress. It looks badass and sounds great. I daresay it takes a step in the direction of the SZ2000's sound with the silver plated copper cable. Everything is tightened up, treble is opened up & far sweeter but still non fatiguing, and bass impact is not suffering more than maybe 5% subjectively at most. Since the extra 5% or so on the stock cable has considerably less definition than the silver plated wire, I will continue to use the silver plated copper. NOT pure silver, that will kill your bass impact, unless that's what you're after . The SZ2000 uses silver plated copper as well. I would not complain if the silver plated copper became standard... and stop putting those little white tags by the 3.5mm Rose!
Tips used on my Aurora are Sony hybrid tips. Once I discovered Sony tips fit on perfectly I have used nothing else (they provide the impact of the stock tips with the clarity of the spiraldots.)
