sad but true.
DUAL was a true non-hi-end item in the days before digital and then folded like so many other volume manufacturers, Thorens, comes to mind here.
The Thorens name got 'picked up' again as was DUAL name, but I think Thorens is looking a bit better then DUAL, which seems to battle the affordable lines of Pro-Ject and the likes. Not sure if their comeback will work, but then who knows.
I had some DUAL stereo (speaker fold-up, all in one) like EVERYBODY and his mother had (then living in Germany in the late 60s - early 70s).
They were work-horses but nothing special other then putting a stack of 45s on a pin (worked well though) and just an OK match to most of the other late 'Wirtschaftswunder' HiFi, for everyone to have some sort of vinyl playback. Just a step up from the 'Musiktruhe' = radio set, vinyl (mono), with plastic tone-arm, and furniture piece all in one. Fitting the kidney side tables with 'smoked glass top or mosaic, brass edge trim and thin long conical legs...
Well, that's DUAL for me -- not too inspirational, shame.
