A 12-page combined DENON and COLUMBIA catalog, issue No.4, January 2001 - the whole Nippon Columbia lineup at once, with the same trumpet, flute and sheet music on the cover as issue No.3 two months earlier. On the DENON side it tops out with the S1 series (the POA-S1 mono power amp at ¥2,000,000, the PRA-S1 preamp, the PMA-S1 integrated), a CD chain from the DP-S1 transport with its separate DA-S1 DAC down to the DCD-S10III, the PMA-S10III and PMA-2000III amps, AVC-A1SE, AVC-A10SE and the new AVC-3500 AV receivers, the DVD-3300, the DP-900MII turntable with DL-S1 and DL-103R cartridges, SC-777SA speakers now joined by the floor-standing SC-T777SA and center SC-C777SA, and the DN-M2300R pro DJ players. On the COLUMBIA side there are the retro “音聴箱” record players (GP-70, GP-38), home karaoke (the new CDV-1700 with a TV and the CDV-500, replacing the earlier CDV-1500), Elepian electronic pianos (EP-G1, EP-3600), plus CDo cassettes and blank MiniDiscs. This may be one of the last combined “DENON / COLUMBIA” issues: in 2001 Nippon Columbia’s audio business was spun off into a separate Denon Ltd., though whether any catalogs followed No.4 is not yet known.
