This is the first german radio that I buyed on the usual auction site
I'm in love from the first time I saw her, and about a year ago I was able to buy it
The peculiarity of this radio is the compression tweeter (schallkompressor) that sounds with two flutes, giving a unique 3D effect. This is the top radio in the Graetz catalogue for 1957, and most collectors think that it has the best sound of all the German radios. Today I have three Grundig, a Saba and two Loewe, but none of them sounds like this Graetz.
