There are 36 issues of '
Copper: Music, Audio, & The Good Stuff'.
Here's their description of the magazine, from issue #1:
The first issue of Copper, now before you, requires a little by way of introduction. Copper is dedicated to furthering the art of home audio reproduction, and growing the community that supports it. Whether you call it Hi-Fi, hi-res, or High-End doesn’t matter; such labels tend to separate and isolate people, which is exactly what we don’t want to do. We’ll do our best not to be audio snobs.

-- By the way, I had no idea (as mentioned in this first issue), that
Paul Kantner and
Signe Toly Anderson of
Jefferson Airplane had both died last year - and on the same day.
