Right now I have Wywires (Blue) between the KWI-200 and the LS-100, and Signal Cables (Silver) for source and speakers wires. The speakers are from Selah.
Mfa 6 500i, with low sensitivity speakers. It's a British amp ,harbeths and the like will be a good synergy.
How can you add a LS-100 pre to the KWI since I can’t see a “main in” set of plugs?
