Very rare mid-sized system taking up where the Series 20 left off. Varied but coherent design, an obvious effort on finish and... good components, too !

The SA-3000 amplifier hides very well its two power transformers and diecast hetsinks behind a deceptively simple front. One of those transformers is a toroidal.
The CT-3000 cassette deck is the one well-remembered as Pioneer, unlike Sony, Victor or Technics, never made an old-style round-VU recorder except this one. The tape being hidden in a tray, an even more old-style remaining tape gauge is fitted into one of the meters. Strange, though, that soft-touch transport keys weren't incorporated into this "design" unit... but this was coherent with old-style styling :)
The TX-3000 tuner seems like an offspring of the japanese F-28 sub-lineup - very elegant with its lit needle window that doubles up as tuning meter.
The PS-3000 is somewhat more previsible but remains almost as elegant as, say, a PL-630 ; no "Stable Hanging Rotor" here yet, though. Supporting all this heavy metal is the B-3000 rack cube. The recommended loudspeakers were market-dependent: tiny CS-X2, big HPM-60 or cool S-X50.

A 1980 addition to the Series 3000 took shape in the SX-3000 receiver. The Series 3000 had the overall name of "Mini Component" in Japan, Mini 1, Mini 3 or Mini 5 corresponding to the various combination of units : the Mini 1 was TX-3000 based, the other two took on the SA-3000 integrated amplifier. But there also were other variants and versions there and elsewhere, too.

If I could cram a DAT recorder into the CT-3000, I really wouldn't mind using the Series 3000 system as main music maker in my home, daily.
