BALANCED HYBRID DESIGN OF FRONT TUBE AMPLIFIERS AND REAR TRANSISTORS

The xDuoo MT604 houses a combination of front tube amplifiers and rear transistors. Adopt four 6J1 tubes for the pre-amp and adopt transistors for class A buffer. This combination of a front tube amplifier and rear transistor combined gives the device the advantage of two amplifier circuits that achieves a full sound.

INSIDE THE CIRCUIT - TUBES + TRANSISTORS

Tube Amplifiers have a unique “tube sound”, which is generally described as sweet, soft, warm and listenable but the high frequency transient response isn’t shiny. To tackle this issue “Transistors” are added into the signal path giving the sound a larger dynamic range and a sheen on the top end. The combination of this makes vocals sound sweet and exquisite while giving the MT604 the capability to output strong power that can easily drive various kinds of headphones.

A good entry point to Tubes

This is a hybrid tube amp. Not exactly the pure tube sound you would want, but if you are new like me, this is a good starting point. The output power is great, this will drive almost all hunger power demanding headphones. The foot print is small so you can put it anywhere. The two volume controls to match left and right is a boon and a bane. Good for people who have issues with volume matching in headphones, maybe one driver is going bad, or just didn't match to the other for some reason. This can help bias correct those issues. Otherwise it takes a little work to match the L and R volume knobs for a center image. They could have inlcuded one master volume knob. Other than that this is a great amp, good resolution, the sound is sweet, with a bit of tube goodness. Still early days, so testing it as I go. Shipping and delivery by the guys at HPZ was spot on. Well packed and super fast delivery, they are damn good at this. You are getting a lot of Amp for this price, can't go wrong with this.

Excellent hybrid amp...great analogue sound

Excellent hybrid amp and excellent price offer you wont get these products too often grab fast.

I used 4.4mm cable from headgear audio and used tempotec sonata e44 as input (Dual dac in e44 is a beast feeding mt604) and even my blon bl01 is performing like $200 iem...what a performance. Just replace power card input cable with local Indian one having earth pin which is missing otherwise you might hear alight hiss depending on your wall electric circuit.
