What is the cost of this product ?
Got one of these to day. In the US on 110v. Used it all day. worked great. No issues. Tried a number of different ohm headphones. None over 100. worked fine with out issue. If anything changes I'll reply or edit my post. the box it came in did clearly say on the outside "110v Only" Though it did come with a 220/240 volt AU/EU plug. Kind of stupid... yeah. I feel bad for the people that didn't notice, or box wasn't marked. Also have a Mullard Pre-Amp tube on order and some Russian gold grid's on order. to go with the massdrop AKG K7xx headphones. I'll update later once built out.

Noticeable improvement on the tube switch out. The Mullard K-61 tube switch was first... The low mids and bass became clear and un-muddled (but wasn't noticeable on 80's and classical music to begin with). The Russian 6S19P-V (6C19P-B) Gold Grid tubes increased my output a bit all around. Also removing a hiss and hum that was barely noticeable to begin with(only noticeable after about a hour of usage originally with the Chinese tubes). To which I have dead silence now even if I max out the volume. Tubes were purchased from Ebay.

Couple months later. This amp is still rocking solid. No issues. Not a single one. Mostly used for USB/Computer audio. Still rocking the Mullard pre-amp tube.
HI Did someone else had a reply already?
gjhartog
Nope. Not yet.

Grtz Good Luck

My TA-03 definitely runs out of steam trying to power my HiFiman H400S. Has anyone achieved appreciable extra gain by changing the Tubes? I've seen a few comments but since it's been a little while now I was hoping for some updated feedback please. Thanks in advance!

Noticeable change in output. See my post above for photos and parts I used. Now you do have another choice there is a UK seller on ebay, selling a Telefunken pre-amp tube that from my reading was original meant for computers back in the day with 130-140 milliamps rating. For 58.04$ USD under the title of 6211/ECC802S/12AU7 TELEFUNKEN on ebay. They tend to be a little crisper and you loose some of that old fashion tube sound, but the higher output will go in to the main amp tubes. May provide that extra punch you need. You'd need to research a bit, but it should work just fine to, but weren't original designed for pre-amp sound from what I read. I choose Mullard because most consider them to be the best after Telefunken. But NOS of Telefunken is hundreds of dollars US. So I bought a used tested Mullard. Some sellers will show you the test output readings on the auction. I would only buy a pre-amp NOS or Used only if this testing values are shown by the seller. My opinon mind you. Mostly because they are two channel, so if they are not balanced... well you get the idea I'm sure.

Tubes are not good for low impedance headphones. Should've went with solid state for a planar instead.
Anyone already heard something from Customer Support?
I turned it on, a POP sound followed, then a nasty smell....and a dead UNIT...
HMMMM
Turns out it seems from multiple sites that alot of the units are 110v only. So make sure to check your box it should be labeled on the out side. Mine was.
Decided to test it. It came with an Australian plug. Australia uses the same voltage as the UK. So I assumed I'd be safe. I was Not.
PieterKdeVilliers
Exactly what happened to my unit. Let's see what customer support will come up with.
jupiterianvibe
And exactly what happened to my xDuoo TA-03 as well!!! Gone in a split second. Alhtough on the site of Massdrop they mentioned 220-110 Volts (so I thought thats OK) they obviously send a 110 Volts amp to Europe in fact to the Netherlands!!! Inside the receptacle on the housing you cab see "250V" by the way!!

Ok great!! I didnt hear anything yet from them. Tnx for the answer!
PieterKdeVilliers
out side on the box it came in did it say 110v only?
Mine just turned up at the door, but I dare not plug it in!
Just checked the spec on this and it states: Power supply: 220 or 110 V But at no point in the ordering process did they ask which one I want. As I am UK based it needs to be 220V. Any word from Massdrop regarding the units blowing up mentioned here?
PieterKdeVilliers
I raised the issue to the customer support just now.
jupiterianvibe
Yeah, I did the same, but no response yet. Will update when I hear something. Anything.
Same as above, received this today, plugged into 220v, turned it on, tubes started to glow, then a lot of smoke, one of the power tubes popped, burned circuitry smell all around, barely managed to unplug before I set the house on fire. What did I do wrong? Couldn't find a switch to select voltage so I thought it arranges that internally. Very sad that my first drop turned into a disaster.
jupiterianvibe
That makes are a bit nervous about plugging mine into the power when it gets delivered tomorrow.
I turned it on... the tubes started to emit a soft warm glow... then a bright flash... a pop... and lots of smoke. Great special effects, but can't say much as to the audio quality. :-(
Is anybody else experiencing noticeable distortion past the 12 o'clock position of the volume knob in (busy) music (like Deorro - Five More Hours? There is no doubt there is a wider sound stage, and many more details present compared to the 3.5mm jack of my Note 5, but it seems there is very little additional volume past the 12 o'clock, and really just more distortion (though it doesn't get completely out of hand). I've been switching back and forth between the stock 12AU7 and a Mullard from upscaleaudio, and the distortion is present either way. Disclaimer - I am not an audiophile, and this is my first 'tube anything'. Cans are AKG 712. Have a few hours on the Mullards, and less than 20 minutes on the stock 12AU7. Honestly isn't very satisfying at anything 12'oclock and under (might as well have the AKG plugged into the Note 5), and this makes it a paper weight for me.

It depends on your headphones I think. My B&W P3 seem fine but my HiFiman H400s definitely need more power than the unit can provide. I do get the same issue where there's no appreciable gain past the 12 o'clock and distortion - very disappointing.
Never made it to 20h, my 12AU7 tube just died... Contacted Massdrop Support, curious to see what they can do.
Just received mine today. Except for the Australian (?) powercord, everything is fine. As I'm on a Mac, no driver issues here. Immediate improvement over the stock soundcard, about 2hrs in now. Will see how it does after a few more hours, happy so far. Will look into getting some other tubes for it as thecomputerdude suggested.
20 hour update- The brightness has significantly mellowed out, but the bottom end is still lackluster. Warm, but not full (Stock 12AU7). Unit runs hot as noted by others, this is normal operation and the reason behind the "must have good draft" warnings in the instructions. The tube heaters are basically compact space heaters which irradiate the metal chassis. There have been zero issues running my Sennheiser HD800 aside from the lacking bottom end.
The soundstage is pretty wide, I've noticed a distinct tendency to "swing" on certain tracks which is a bit uncomfortable. There's pretty much no cross-channel mixing, left is left and right is right, center works very well when the signal is balanced. The amp clearly prefers the left channel at lower volume, hopefully this bias will go away when I swap tubes.
EDIT: Just swapped in a Matsushita 7316 (12AU7). I'm floored by how much wider/fuller the sound is vs the Chinese tube. In this particular amp I think the Matsushita is just phenomenal. It does lose a slight amount of gain compared to the Chinese version, but turning the knob a little further is a small price to pay for the immense improvement in sound quality.
There is an updated driver for the TA-03 XMOS chipset, version 2.23. It can be retrieved from xDuoo's site via the Downloads section.
Received mine today. Aside from the fact that it came with a 250v Australian IEC cable (I'm in the USA) it works as expected. Still breaking the stock tubes in to see how they perform- initial impression of the Chinese 12AU7 is that the bottom end is very mushy and the top end is very bright (I was expecting mushy all around).
I'll post back with results after 20 hours of use or so- I have a Matsushita to put in afterwards.

It's the end of the day, any news for us?
Some people mentioned on earlier drops that the volume is not that good. Changing the tubes would improve the issue, but as I'm not well versed in tube amps, can someone : 1. Explain which tube does what on this amp 2. Which tubes can replace which, and how they size up.
Thanks !

Thanks for that. Will look into getting some 12AU7s and testing them. If I'm not mistaken, you should allow some hours on the tube for it to come to full capacity?
SimonSays
Yes, depending on how tight the valve is, can be anywhere from 5-15 hours of playback. Don't leave them on without signal until they are broken in on your music of preference, they'll develop a stiff sound in particular frequencies otherwise.
Did the units ship yet?
Are they going to send any shipment notification or tracking number?
I will monitor this one I'd love to see a drop with both a decent headphone and amp for those of us looking to get into our Audio some some good kit
50USD shipping? Forget it.
Will.Madeley
Shipping says FREE for me. Are you outside the US?
I'd pay extra to have rca outputs on it. Without it it's not worth it. Then could use it to clean up the audio going to my 7.1 stereo system. That would be worth it for sure! Great design, but really wish you had put extra outs on it. Hell even xlr outs, coulda used it will mixing tracks maybe.
dairyman3833
The RCAs become outputs when using USB audio. They're tied directly to the preamp stage with the DAC outputs.
Any chance they have a silver version? Instead of the black?
Vinyljunkie8
what's wrong with you?
This thing (or the next iteration) needs a SPDIF input. Want to Chromecast Audio into this, which has either 3.5mm or SPDIF. For now, I'll just use the USB ouput of my phone. Hopefully some with xDuoo's ear will suggest that for the future.
Hey cool, there's a North American plug this time.
