I had the same receiver along with a pair of Celestion Ditton 15's in 1984, Bought them at a used stereo store when I was in the Military. I left them with my sister when I was posted and upon return a year and a half later she had allowed my brother in law to take the to his place of work and they somehow just disappeared. I was 23 at the time, 63 now and it still bugs me. It was nice to see the Marantz in action again. Thanks.
