In my many years of listening experience, AMP3 should be used in pure Class A amplifier circuit!
1, it is also very warm and the sound is very full-bodied, while rich in detail and also has a very powerful dynamic, this trait in common DAP (such as the IPOD, SANDISK) is certainly not heard it, it exists only in high-fidelity Pure Class A circuit.
2, I took the same first caballe singing "Grandes Heroines Lyriques" in AMP3 and the home in Pass ＋Focal mini utopia of pure A class Hi-end systems were repeated comparison and found that their voices are surprisingly similar qualities! caballe voice rounded out sweet but also just right to express an appropriate degree of heroism, it sounds, very enjoyable, the music and the instrument separation is very meticulous, and orchestral sounds of the wooden pipe is particularly the sweet, the sound of the gloss and brightness is so just right, wind blowing in a circular shape is so true, even if the flow from the highest point we do not think there is a trace of reluctance, but also people think there are many margin, this instrument can express the characteristics of degree of texture or even warm I also only in the most high-end pure Class A sound system in the taste, but the AMP3 have this trait!
3, I like singing in a choir once spent a period of time, so I am solo and chorus are very sensitive, there is a singing technique is able to explain the nature of a pure A class circuit, we sing when asked to do every note must be sent to maintain the same energy level voice control, even in the weakest sound at too. Using AMP3 listening Carreras's "South American mass", it is perfectly expressed this only in pure class A circuit can be Jinxian advantage Carreras bright high-pitched voice can make your with emotional pitch with him to climb in a warm, but there is the need for a large number of songs in a rich atmosphere of the chest supported damper handle is beautiful and moved people to tears, and only pure Class A circuit in order to provide the same at any time, a powerful energy the performance of the supply of these sometimes as low as the Ministry of the details can not be heard in the dark.
Thanks hiflight for this great fair and honest review!thanks hisoundaudio able to provide such a good product, I must say, can buy DAP have such a perfect sound quality of all the happiness of the people who love music!
