During my 100 years on earth, I've owned mostly separate amps and preamps, but only because that is where I startedor I should say, that is where my audio-savvy friends directed me when I began asking for guidance. Nevertheless, the audio system I've used the longest (unchanged for almost 10 years) consisted of 1984
Rogers LS3/5a loudspeakers (15 ohms, with factory wall mounts) powered by a proletarian-looking Creek 4330 integrated amp sourced by an Oppo CD player.
