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.

ENTHUSIAST CAPACITANCE

xDuoo MT604 includes the special enthusiast Japanese Rubycon Capacitance as this coupling capacitance has a transparent and sweet sound. Paired with this is also the Nichicon capacitance as the main filter capacitance which outputs a smooth and warm sound with open high frequency.

BUILT-IN MUTE CIRCUIT WITH BALANCED INPUT AND OUTPUT

xDuoo MT604 has a built-in relay for muting the circuit when it is turned on to avoid POP noise and to also ensure that the tube is working at its optimum condition. xDuoo MT604 also offers XLR and 4.4mm Balanced input, 4-pin XLR and 4.4mm balanced output. This makes the device suitable for many kinds of balanced headphones.

INDEPENDENT GAIN ADJUSTMENT CONTROL EMBEDDED IN A SANDBLASTED TEXTURED PANEL

The panel for the MT604 is designed to give you the freedom to adjust the volume of the left and right channels separately to reject the sound-bias problem. The exterior panel for the device has a beautiful sandblast textured panel encased in a hard aluminium shell. This is an engineering feat as the panel and shell are slap-up and can resist external interference efficiently.

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.

A little beast of an amp

I wanted to enter the realm of tubes, having heard so much about the musicality, warmth, slam and punch that tubes offer. When I ordered this chic looking guy I was a little sceptical, but confident that I wouldn't be disappointed, since all the reviews are favourable. I used my ef400 xlr output to the amp and heard it via the XLR output on my he1000 se. It was warm, spacious, wide and utterly musical. It made my ef400 which was what I was listening to earlier sound a little dry and sterile. The hifiman ef400 is already a great dac/amp combo. In my listening test it came out a hair lower than the hugott2, which is the pinnacle of amps, at a tenth of the cost. When I added the xduoo 604 to it, the music sounds terrific, and that's even before the burn in. I think it beats many higher priced amps in the performance to price ratio. I'd meant to review it later, after some burn in, but once I got the ultimatum, I am very happy to review it right away and it has my fullest recommendations for anyone who wants to know what tubes sound like. Tube amps defy any description, analysis or words that qualify solid-state amps. They need to be heard, then there's no going back. The journey has begun, now the quest is on to acquire the endgame tube amp, and start the education on tube rolling. This phase of the journey is tough and will keep me busy for a long while, sustaining the fascination for acquiring the holy grail of a near perfect music setup. I'd like to request headphone zone to add some more tube amp companies in their repertoire, like auris, Felix audio, Manley, etc.

We really appreciate the genuine feedback, we'll share your thoughts with the brand as well!

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.

Dual Volume Tube Fun

This is what I'd call a "fun" sound. The dual volume controls mean that you can alter the soundstage to suit your preference. That's awesome!
