To be honest, when this whole thing came about, I actually did a couple passes of 2 different CD-4's and one of the Q8. While my CD-4 sounded pretty good, this sounds GREAT. I would have loved it to be one of my passes but, to me, this sounds the best it ever has and I have had MANY copies. it's really clean and crisp sounding. There are no "nasties" of any kind that are present.
