D5 uses one pair of large pipes D5Pro uses 3 pairs of large tubes to increase thrust, the rest are exactly the same
D5 R&D process
The first generation D5 pure rear stage was launched in 2015
Launched D5 merger machine in 2017
In 2021, the D5PRO merger machine was launched, which increased the number of power tubes per channel from 1 pair to 3 pairs in parallel
Line characteristics
Round Moon Bending Knife "Da Xiao Wu Large Loop Feedback Amplifier Circuit
Warm, soft, comfortable, and pleasing to the ear, this is an amplifier suitable for sitting down and slowly listening to music. The sound is quite smooth, open, and natural, without any noise, which is quite pleasant to listen to. In terms of bass, the volume and depth are both good
High damping coefficient, can control any speaker freely because it is a feedback amplifier without a large loop, with first-class control power, worth a try
MBL preamplifier circuit, powered by independent parallel stabilized power supply
3-channel RCA signal input selection
Production materials
D5PRO adopts 6 pairs per channel and 3 pairs of precision test pairing ON MJL3281/1302 high output current capability
All small signal lines and high current lines inside the machine are made of Taiwanese PTFE oxygen free copper wire
