78's I think acoustical reproduction and electric reproduction are 2 separate categories. A Victor scroll electric or Columbia ViVa tonal from 25-29 were recorded w/the assumption that reproduction was for state of the art players credenza and the biggest Viva tonal-at some point 28 or 0 the recording technique changed in 28-29- to western electric or VE w/assumption that these would be for state of the art electrical reproduction-all kind of odd in that probably most people were playing records on machines made before 25 and if they invested in sound equipoment it was a radio. One might argue that the bass upfront Orthophonic sound is a false esthetic-I love it anyway. I have always wanted to hear one of those british EM Ginn machines-they continued to make external horn acoustics I think into the 30/s. these days its cd's in the car-but when time permits the edison baby console and Credenza (both were restored tone chamber and reproducer)will be retrieved from my folks basement-the fidelity is really amazing w/restoration and a mint 78. acoustic 78s pre 25 really sound better on a machine w/smaller horn the consolette works well enough.-I did compare a colunbia gramophone and Consolette playing acoustiuc 78;s -victor won out. If the record is mint thorn needles are great -period sharpening ephemera is cute but I used to use a Dremel mototool and fine sand paper to sharpen. perhaps I am nostalgic for the period in my life when I had time to deal with and learn about this stuff!
