IWISTAO Headphone Amplifier Discrete Component Pure HIFI Class A Amp Lehmann Upgraded Version Plastic-sealing LM47910
This is a pure Class A headphone amplifier that is made of discrete component. High signal to noise ratio, you will not feel the unit is working if its LED don’t light, and you cannot believe your ears when listening to background quiet, very clean sound at the end. Powerful drums and drum points are precise distinct, as well transparency, layering, positioning is very good The overall feeling of the sound is smooth, plain, plump, good separation, warm timbre, high resolving power, dynamic large, high-frequency extension also is very good, a strong sense of air, gorgeous atmosphere, for a long time to listen not tired. Large driving force can be pushed all kinds of headphones (range from 32 to 600 ohms). Headset to play as much as possible the original style, taking the sound balance, relaxed, listen not tired for a long time.
1. Used 30W high R-type transformers.
2. Independent power supply designed, this is more important, you can reduce impact of the power section of the amp, high-end amp only use an independent power supply design; used six capacitor filter, ensure adequate large dynamic currents, there will not be lack of low-frequency and no sound divergence situation.
3. 2 channels independent designed, independent headphone protection is also two relays to improve channel separation, increasing the SNR.
4. Increase driven switch that can fit most current high-end headphones.
5. Coupling capacitor used in Germany ERO capacitance MKP1813, plus the latest Weimaraner film capacitors, good performance of high middle frequency and resolve improved, detail perfect.
