On the basis of the original, the new DP34 has enlarged the shell size, upgraded the power (290W) and size (105 iron core) of the power supply cow, and the output cow has also been fully coupled (standard 0-4-8 ohms, It can be changed to 16 ohms by changing the wiring), and the application of imported CMC sockets makes the overall performance level higher.
