We all know how much improvement a good NOS (New Old Stock) tube can bring to the sound quality, therefore, start today, we will have a new model Tube Magic D1 with a brand new GE 5670W military version tube pre-installed. If you plan to use the tube preamp out on the D1, then it is a must-have upgrade.
