From my experience since I own the CD-2, sure the combo sounded better than my Belles 21A Auricap but I'm not at the point of getting rid if my pre because the CD-2 and what I have heard from other CD-5 users is that these unit just doesn't have the gain at moderate levels but beautiful at low volumes. Since we're talking about, I'll do some comparison tonight at low levels since my kids are all tucked in.
