xDuoo MT-601 and MT-602 Tube Amplifier Preview
by SHENZHEN AUDIO on Jan 07, 2021
xDuoo have a good reputation in the china audio industry with their best selling products like the XD-05 plus portable headphone amplifier, which adopts XMOS XU208 and AK4493EQ chips and supports up to 32Bit/384KHz and DSD256 signal. And their good quality products such as X3II digital audio player and tube amplifier lineup “TA” series including powerful TA-30, TA-20, or the latest USB type-C ESS9118EC chip Dac connector the xDuoo Link2.
xDuoo have planned their new product lineup for a while, and now they are going to release their newest mini headphone amplifier MT-601 and MT-602. Another product lineup "MT" represents mini tube amplifier which mixes tube and transistor in a tiny box. MT-601 will be available on Jan 7th, priced at US $89.00. While MT-602 will be ready for sale on Jan 8th, US$ 99.99.
MT-601 is a high performance tube & class-A headphone amplifier. The pre-amp adopts 6N11 tube to process audio for the audio giving exquisite and tender sound, and the post-amp is adopted transistors for class A buffer, with strong load capacity, it can easily power the various kinds of headphone, whatever you throw at it.
With a AUX output, which through tube processing, and can be contrlled by the volume button, you can connect to active speakers, making your speakers more flavorful. The power supply adopts 24V DC input. After professional power processing, not only the amplier can exert its maximum performance, but also the weight of the machine is greatly reduced, and the volume of the machine is also reduced, making it more lightweight and portable.
Science knowledge: About tube + transistor hybrid amplifier: Tube, has its unique sound, the sound is sweet and soft, warm and durable, the music feels good, and the atmosphere is good; its shortcomings are the transient response to high frequency, the resolution is not as good as the transistor amplfier, listening to some symphony and other songs Especally obvious.
Transistor, the advantages of transistor power amplifier are large dynamics, fast speed, high resolution and strong driving force, which is especially suitable for the performance of moredynamic music; its shortcomings are low frequency The sound is not soft enough, and the high frequency sounds are sharp and dry.
Power Source: DC24V/1A
Output Power: 200mW(32ohm)
Frequency Range: 10Hz~ 60KHz(+0.5dB)
THD+N: 0.8% (1KHz@32ohm)
Suitable Earphone Impedance: 16~600ohm
MT-602 is also a mini amplifier which adopts dual 6J1 tubes for pre-amp to process audio for the audio giving exquisite and tender sound. And the post-amp, same as MT-601, is adopted transistors for class A buffer.
Therefore, the pre-amp used tube and post-amp used transistor, combining the advantages of these two power amplfer circuits to achieve the ideal musical effect, you can devote yourself to the, joyful atmosphere of music.
