By far we see more Quad 405 amplifiers than any other product. The Quad 405 was manufactured up until the 80's. the Quad 405 was revolutionary in it's design with being the first current dumping amplifier. The Quad 405 had basically two different versions the last in production incorporating a speaker protection circuit. The Quad 405 though legendary cam be improved upon by utilizing better opamps and output transistors. Dada Electronics stays true to the original design of the Quad 405 because it is sound rather we upgrade the Quad 405 components to a higher grade. There are many different levels to upgrade the Quad 405 and as you go up the ladder with price there is a diminishing return but none the less an improvement of the Quad 405 at every level.

Who We Are

We fell in love with Hifi-design from the 60's and the 70's, and use our craftsmanship and dedication to put new life in those Quad's, B&O's, Naims and Revoxes. So if you want to get the dust out of your ears, pick these amps out of the attic, ship them to us and they'll be returned in no time better than original, once more ready to take the prominent place in your sound system they deserve.
That's why we decided to establish Dada Electronics.
Dada also specializes in getting you those hard-to-find spare parts, audio-grade cables and components at a reasonable price. We now stock EVERY circuit component for every model Quad ever produced.

We try very hard to earn your trust for today and the future by providing the highest quality workmanship available!
