Quad II-eighty Mono Power Amplifier

The Quad II-eighty Mono Power Amplifier is a modern classic and designed by valve supremo, Tim DeParavicini, the II-eighty is much more than representing homage to the Peter Walker classic – it’s a complete re-interpretation of the philosophy. Using 4 x KT-88s and a similar cathode coupled output, the lineage is clear to hear and see, but with such huge dynamic headroom, this amp is faster and with more control than any previous model.
