It isn't always easy to find cables with an airy and extended top end that don't lack bass. In my experience MIT cables work great, Nordost also falls into this category (although I don't care for models Red Dawn and below - they have grainy treble), Chord cables, and Supra cables. Find some models that fit your budget and try them. Certain van den Hul like Orchids have an airy, extended treble too. Some say in general that all-silver cables do too but I find this tends to vary.
