If the present cable is also only 1.5 feet or so, I would not expect that changing it will affect the treble significantly.
If the present cable is significantly longer than that, reducing the length and selecting a cable having lower capacitance per unit length may help, to a greater or lesser degree depending on the output impedance of the component driving the cable (the higher the component's output impedance, the more difference it would make).
Blue Jeans LC-1 offers very low capacitance at a very low price. Oyaide PA-02TR, available from The Cable Company, also has very low capacitance, at a somewhat higher price.
IMHO. Other opinions will differ.
