Some Common Issues with Londons and Deccas
Many London and Decca pressings lack weight down low, which thins out the sound, easily heard in the lower strings, which sound washed out.
On some sides of some copies the strings are dry, lacking Tubey Magic. This is decidedly not our sound, although it can easily be heard on many London pressings, the kind we’ve played by the hundreds over the years.
If you have a rich sounding cartridge, perhaps with that little dip in the upper midrange that so many moving coils have these days, you will not notice this tonality issue nearly as much as we do.
Our 17Dx is ruler flat and quite unforgiving in this regard. It makes our shootouts much easier, but brings out the flaws in all but the best pressings, exactly the job we require it to do.
Here are some other records that are good for testing string tone and texture.
