The Turquoise Instrument cable uses the Sommer SC-Spirit cable. The Turquoise has a super-low capacitance of 23.8pF/ft to allow all your frequencies to come through. The tight braided shielding prevents electro-magnetic and radio frequency noise from getting through. It looks beautiful with its Turquoise MDPC sleeving and gold G&H plugs with nickel housing. Contemporary design with vintage style.
