这是和1073 DPA的区别:
The DMA ia far superior to the DPA
1st: Features that DMA has and DPA does not:
- PAD
- Hi Pass filter, an all discrete class A one
- DI: an all discrete ultra high impedance class A jfet feeding the input transformer.
2nd: how it is made
- DPA is SMD technology ( modern micro components )
DMA is made the old fashioned way, with same components as in the vintage 1073.
