I have a lovely pair of Spendor SA 1's which I've just got past the break-in stage. My previous Harbeth HL-P3's has a a little more air in the treble and a little more bass weight. On the Other hand the Spendors image slightly better and are definitely less compressed in dynamics. I would like any recommendations on a suitable partnering cable that will give the treble a little more zing whilst maintaining bass weight. I'm currently using same Ecosse reference 2.3 speaker cable.
