Cambridge CXA60 - Knob Feel Review Cambridge Audio are back, but with a shorter name and nicer Knobs. Volume, Bass, Treble and Balance all make an appearance. Bass and Treble are a little to attentive on the protrusion, whereas the Balance is dampened and smooth on the rotation. Volume, being the big boy, seems to have taken some notes from the 851A previously reviewed. Lovely smooth rotation with a little weight behind it. Axial skew is present, but not a game changer. Cambridge are back and taking Knobs seriously!
