BIGGER = Better ?

cassette deck

These are some of the BIGGEST cassette decks ever made. Were they better than a regular sized deck? In some cases, yes, they were hiding complex mechanical construction and sophisticated electronics to achieve the best possible sound. Let's take a look at the models and the years they were made.

The AKAI GXC-570D was first manufactured in 1975 and it features 3 heads and 3 motors.

Here is something interesting, something you would not expect. This is the 3 head UNITRA MDS-624 from 1983....apparently only a prototype...

Finally, the BIGGEST of them all but never manufactured. The LUXMAN X-3K, only shown as a prototype in 1982. With this system the aim was to completely extract the tape from the cassette and run it on a free and precise tape path.

Quadraphonic - Surround Sound Amplifiers


Quadraphonic is a forgotten Surround Sound system from the early 1970s.
This system used four channels with speakers positioned at the four corners of the listening room. It was never a huge success because of the expensive equipment, conflicting formats and available albums. True, four separate channels, were used in the UD-4, CD-4, Quad-08 and Q4 systems. A different approach was the encoded system where the four channels were converted (encoded) in two channels (usually a vinyl LP) These records were decoded with a decoder in four channels. Some of the formats were the Matrix H, EV-4, and the completely different SQ and QS.

Here are some examples of quadraphonic amplifiers and decoders made in the early 1970s.
