Clone Dartzeel D5 Ultra NHB-108 Hi-End 300W HiFi Stereo 2.0 Channel Amplifier 150W+150W 1:1 copy Dartzeel NHB-108 Line 2-channel Power Amplifier Natural Sound Low Distortion High Power HIFI Audio Amplifier Sound characteristics: This is an amplifier that is suitable for listening to music in a relaxed manner. The sound is very wide, open and natural. Suitable for long-term use and pleasant without sharpness. Regarding the bass, the sound is blessed with great volume and you can immerse yourself wonderfully. The power amplifier works without much feedback, with first-class control of the connected speakers. It's absolutely worth a try. Product introduction: We have upugard the BC capacitance and Aluminum Feet for D5 Ultra Version. 1: The main amplifier circuit is derived from the Dartzeel-NHB-108, a famous machine with a price of around $50,000. The circuit matches the original 1:1. The selected components also correspond to the original at the key points in the sound and therefore no compromises have to be made in terms of sound compared to the original. 2: The secret of the Dartzeel 108 power amplifier is the design of the power amplifier circuit, which operates almost entirely without a feedback loop. Effects on the sound caused by feedback are completely eliminated. The sound is natural, open and the connected speakers are well controlled thanks to a power-coupled output stage. 3: The patented circuit of the amplifier runs very broadband due to the revolutionary design, has a powerful current delivery capability and therefore this incredible sound quality. 4: Due to the lack of an entire feedback loop, compensation networks that influence the sound are also omitted. It is an "open-loop design" with only 6 transistor blocks in the signal path. 5: The short signal paths in the amplifier design are the guarantee for outstanding sound quality. An additional circuit ensures that no DC components reach the output and the rest voltage is below 1mv. The stereo channels are completely separated after the transformer, which reduces crosstalk and other interference to a minimum. 6: A very quiet toroidal transformer with 800 watts for the Ultra version rounds off the setup perfectly. In addition, the Ultra version has an inrush current limitation for safe, problem-free operation.Note: No cables are included
