"This quad was a birthday present to my son, they were replacing a set of JJ’s which had been in place for a number of years in his Leak TL12+ Mono-block amplifiers. He says they are definitely louder and give more body to the sound of his CD player and streamer." - R.G.bought Tung Sol 7189 matched quad 27th April 2021
