Hi folks. I'm new here, big music fan but not got much of a technical head. I'm sorting out a home set up at the moment, so I can get the turntable up and running again. I've just picked up some great Leak sandwich speakers that I'm really happy with. I've just seen a Leak Delta 70 amp I like the look of. Seller seems like a trusted vintage audio vendor. Two questions: The speaker connections on the amp look different to what i've seen in the past, does anyone know what they are? Do you have any speaker cable recommendations? Thanks very much. Cyrus.
