I used to have a couple of metres worth of assorted audio mags: Hi Fi News; Hi Fi News & Record Review; Practical Hi Fi, Popular Hi Fi and Audio, Hi Fi Choice, Hi Fi Answers; Audiophile; Hi Fi Review; Stereo Sound; Stereophile (and a copy or two of The Flat Response
). A few of them have been kept, but with most I tore out the arlicles that were of interest to me and threw out the remainder.
Copies of the manuals and manufacturer's brochures have been placed in The Knowledge for reference.
Nowadays, with an average price of £6, I rarely buy the mags - I'm tired of reading about £5K preamps, £20K powe ramps, £25K speakers and £5K cartridges; let alone £1K cables.
