Notice：
D5 uses 1 pair of large tubes, D5Pro uses 3 pairs of large tubes (increases driving force), and the rest are exactly the same
After-stage power amplifier circuit:
The main amplifying circuit of this machine is derived from the dartzeel NHB-108, a famous Swiss machine with a price of 130,000 yuan. The main amplifying board adopts a 1:1 direct reproduction of the original machine. The component models and parameters are completely consistent with the original machine. The sound is exactly the same as the original machine. The dartzeel NHB-108 power amplifier adopts a power amplifier circuit without large loop feedback, which completely eliminates the influence of the horn back electromotive force on the power amplifier. The sound is natural, comfortable, and powerful. The highly acclaimed NHB-108 patented minimalist broadband circuit, a unique revolutionary design, has a strong current output capability and incredible JI ZHI sound quality. There is no global negative feedback, the input and output stages do not have any negative feedback or compensation network, and the unique output stage open loop design. There are only 6 transistors per polarity in the entire signal path.
The sound of this unit:
This is an amplifier suitable for sitting down and listening to music slowly. The sound is quite stretched, open, natural, not noisy at all, it is quite pleasing to the ear. In terms of bass, volume and dive are good. Because there is no big loop feedback power amplifier, the control is first-rate, it is worth a try!
Transformer: Special customized audiophile grade Nippon Steel transformer, no vibration, no call, low voltage drop rate, pure copper wire winding, better shock absorption, is a rare audiophile transformer.
Local parameters:
Each machine uses 12 ELNA FOR AUDIO audio dedicated electrolytic capacitors
The left and right channels of the power amplifier part of the rear stage are completely independently designed to reduce crosstalk interference
Preamp is powered by an independent power pack
Output power: 120W/8 ohm
Signal-to-noise ratio: above 110DB
Distortion: less than 0.005%
CNC machined standard size aluminum case: W430*L314*H110mm
Whole machine weight: 16kg
Static power consumption: D5 85W D5PRO 90W
The pre-amplification part used by the combined machine:
Using the classic MBL6010 pre-core amplifier circuit
Bile-flavored op amp OPA604AP with tube tone
The ALPS27 type potentiometer is rear-mounted to shorten the signal channel and reduce the noise
Potentiometer extension rod connection, short signal transmission path, reduce interference
Preamp uses a Class A shunt stabilized power supply with good transient response and extremely low noise.
OMRON relay signal switching
CMC high quality RCA terminal
The distortion of the machine at full power is as low as 0.003%
A pair of tube amplifier boards used in D5
Three pairs of tube amplifier boards used in D5Pro
