Is it okay to plug the rca line out into another amplifier, will this bypass the amp at line level
Has anyone asked xDuoo if a 12ax7 tube can be used with this amp and if there are any hazards, expected sound problems? I've found a Genalex Gold Lion 12ax7 locally at a good price but I'm still not sure if I should take the risks. I've read that "upgrading" a 12au7 (mid gain) circuit to a 12ax7 tube (high gain) can cause circuit overdrive and god knows what else can happen.
Please advise if you have such experience. Thank you!
My TA-01 made it to Europe the other day and I already modded it with a Socket Saver Tester + Black Tube Guard. It took some unexpected drilling of larger holes for the tube guard bolts but the result is eye candy.
I'm still waiting on my new headphones to arrive but this thing sounds fabulously warm and tight even with a JJ Electronic standard 12au7 tube. I got rid of the Chinese stock tube on my 2nd listen. Let's see how it sounds after burn-in on my forthcoming Beyerdynamic DT 880 250 ohm.
PS: it was 100% plug'n'play with Windows 10, zero drivers required. They didn't work anyway.

yes, I'm using a "12au7 socket saver tester" from ebay - https://www.ebay.co.uk/itm/1PC-Bakelite-9Pin-Tube-Socket-Tester-Saver-for-12AX7-12AU7-6DJ8-EL84-Gold-Plate/191783356390?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
And the tube guard also from ebay - https://www.ebay.co.uk/itm/1-x-Black-tube-guard-protector-for-12AU7-12AX7-ECC83-solid-aluminum/272578054447?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
IMPORTANT: You will need to unscrew the top "grey plate" from the original panel. There are 4 tiny screws and mine were covered in red silicone which slowed me down unscrewing them but it is doable. After you unscrew the top grey plate you will have 4 empty holes and 3 of them are exactly matching the design of the Tube Guard, so you don't need to drill new holes on the top panel. The next problem is that the holes are not wide enough to directly screw the tube guard on, so I had to widen the holes just a tiny bit to accommodate the screws for the Tube Guard. To widen the holes you can use a drill or do it manually by hand using a 2.5 hexagonal screwdriver to get in (BE CAREFUL) and then get a 3.0 hexagonal screwdriver to just slightly widen the hole. I did it with the hexagonal screwdrivers but be careful. Everything took me about 1 hour to complete.
See my review and unlock 32-bit. ;-)
Just do the folders 1,2,3 etc. Let me know how it goes?
Hi All
I realize my folder was incomplete, https://drive.google.com/open?id=1dAPrE9w1vGjcApPwF0p6S_p5l863WJmc it now has instructions the usb driver, xmos update, firmware update and some foobar stuff. I also suggest getting a socket saver. https://www.ebay.com/itm/9Pin-Bakelite-Vacuum-Tube-Socket-Saver-base-For-12AX7-12AU7-ECC82-ECC83-amps-P/113011138261?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649
Install driver and update firmware then enjoy a 32-bit rev.B TA-01. https://drive.google.com/open?id=1dAPrE9w1vGjcApPwF0p6S_p5l863WJmc

Nevermind. I was able to extract it and found the instructions. Very helpful!
Hi yea unzip it and install he xmos driver then follow the document xduoo sent me and apply the firmware. This was annoying me for a long time and I must have sent them about 5 email support requests, They might have worked on it after I emailed them as this updated version (non wolfson) needed the updated firmware.
A quick comment about the TA-01. I purchased one a some time ago and subsequently posted some pics, in this forum, which show the pair of CS-4398 chips inside. I sold that unit and quickly regretted it. So, I've since re-purchased an identical unit. My primary headphones often get heavy after long sessions so I like to wear the K7XX for casual listening of news-clips, youtube, etc. I keep the very light K7XX's plugged into the TA-01 for an outstanding setup I can wear and enjoy for hours. I plan on keeping the TA-01 to compare against other dac/amp combos I buy & sell. My overall impression from the TA-01 is indistinguishable, to my tinny ears, from the Fiio E17K/K5 combo and even the Fiio X5iii/K5 combo. The presence & punch of my Mojo/CTH combo is in a different league than the TA-01 but so is the cost. The TA-01 is easily worth the $119 you can get it for in this drop or elsewhere.
Need the actual driver.
What is the last price of this Amp/dac ?

I am going to get the magni3 and modi2 as schiit stack to run my beloved 4xx
Hi everyone, since I'm new to the tube world with this entry level DAC/Amp I've done a LOT of reading in the last 5 days and came across a very interesting article about tube fakes. I now understand, how "profit-oriented" this tube market can be. Imagine factory workers from ex-soviet countries selling low-quality/defective 5000 Tesla tubes, yes 5k (which had to be destroyed) to fakers, who then re-branded them as Telefunken ECC803s (the holy grail and sold them for $$$). Both workers and fakers make a profit, the buyer is paying a lot of money for his "belief" in someone's credibility.
I'm coming to the conclusion that a lot of people have paid 3-digit $ for something that is not really "original". So my advice is: if you see a Telefunken ECC82 or 802s on sites like Amazon and Ebay, it is not there out of a sudden, and don't rush a purchase. I'm based in Bulgaria, where old stock of Teslas is still found in someone's closet or old warehouse, prices are still upward of $30 (and I'm not sure if these were not mid 1990s JJ-built stock with Tesla parts, after Tesla factory equipment was sold to JJ or EAT). As a reference modern day EAT ECC803S Cool Valve Diamond is priced at € 180.00 a piece http://www.europeanaudioteam.com/en/eat-ecc803s-cool-valve-000009.html . I tend to believe that modern-day tube valve production process must have gone a step forward.
Here is the article that I read and was amazed of how the NOS market works - http://www.jacmusic.com/nos/images/Fakes/index.htm
In the end I might settle for a newly built JJ ECC802s gold, so that I know I'm not screwed and this is an honest copy of the Tesla / Telefunken design, built with contemporary equipment. What do you think about all this?
Electro Harmonix Gold are impressive. I dare to say I prefer it over the Genalex.
JJ tube is a little crisper than stock but the Gold Lion tube is pretty darn sweet, getting some serious low end off this thing.
EDIT: Many months on I have many tubes, the JJ was faulty so returned it and the Gold Lion as it wasn't sounding right. I did get a gold pin Electro Harmonix and it is pretty good.
I now also have a few NOS tubes:
Mazda(cifte): Best imaging, almost holographic with a warm low end. Sylvania: Best low end, dark sounding but good with EDM. Mullard: Best mid range, if you want crisp and lush this is it. RCA: Good all rounder, a satisfying tube indeed. Westinghouse: lot's of clarity but not harsh a pleasant tube.
Anybody else have the volume level just drop and decreased power across the board. Same thing with two tubes. EDIT: was a software issue set to do nothing. https://i.imgur.com/sIe78gB.png
Hello everyone. I finished my review and measurements of TA-01. It is posted here: https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-xduoo-ta-01-and-schiit-fulla-v2-dac-and-headphone-amp.3105/
Let me know if you have questions or need something else measured before I send it back to its owner.
Why it uses the Cirrus Logic, direct from xDuoo rep.
"Because the WM8740 cann't be decode DSD signal, So, we change to Cirrus Logic's DAC in new version, so, the TA-01 can support DSD128 now"
Yes I've compared both chips on the Cirrus Logic's website (you can find both Wolfson and Cirrus model there) and DSD was the difference. I believe they've made the right choice. Plus Cirrus chip is released 2015, while the Wolfson is a 2010 model. I have a Wolfson on my Pioneer CDJ900
I just put a Gold Lion in and it sounds very sweet indeed.
No cassette player, no tuner and no CD player? I'm out'a here!
you forgot the 8 tracks
Most everyone has!
I'd be up in arms if I paid for a DAC with dual Wolfson chips and instead got Cirrus Logic 4398. While not a horrible chip, it's cheap and you probably already have one either built into your PC sound (unless it's using Realtek) or on a sound card.

It could be the tube. Do you have a spare? You can get some good deals on tubes for tube rolling.

Have my Gold Lion tube will be testing tomorrow. The JJ I tried sounded better but was faulty.
I am very happy with this $119.99 DAC it has quality comparable to my $190 FX-Audio DAC-X7 and superior to lower end DAC's. It also has more power, to my ears more than double in comparision to the DAC-X6 and DAC-X7 and they are also both 12v. I am using with my Alpha Primes and it's awesome. Considering selling my other DAC's and getting a higher end xDuoo now.
Overall very happy and now I am ready to tube roll!
EDIT: Just popped in a $10 JJ 12au7 tube and it cleaned it up really nice, not that sounded bad but it is better to my ears. Might buy a Genalex Gold Lion now.
Just got the Ta 01, everything works perfectly, setup was easy, just plug and play.
Hi, when using this as a DAC via usb can you use the RCA out simultanesously with the headphone out? Say you're sending the signal to separate powered speakers while also listening through headphones.
Yes. but the signal strength would be split.
Get this or the bravo with motherboard sound. The motherboard is from the Alienware Aurora R6 with 7700 and 1080.
Here are two great starter DAC's are the FX-Audio DAC-X6 or the SMSL M3.
The Bravo will still need a DAC and the two I mentioned above are all in one units dac and amp. I am selling DAC-X6 with 2 extra opamp chips to modify the sound.
Is the dac in smsl 793 II better than the dac in the fx audio x6 ???
Any suggestions on tube upgrades? I got Tong-Sol and Mullard reissue tunes made in Russia, they appear to be the same visually and i can’t hear any differences between them. They do sound better than the stock one, slightly more detailed with more body and better base. But even stock one isn’t too bad, sounds better than my more exensive solid state amp.
Have anybody tried JJ, Grove, EHX or Genalex tubes?

Have a $10 JJ and it is better than the stock tube to my ears. Highs are clearer and less grainy to me. https://www.amazon.com/JJ-Electronics-12AU7-Preamp-Vacuum/dp/B0002M728O/ref=sr_1_4?ie=UTF8&qid=1524851039&sr=8-4&keywords=12au7 for $10 you can't go wrong.
Added Tungsram ECC82 NOS tube to my collection :) If somebody is looking for more neutral sounding tube, it's a good option ($16.99 on eBay, https://www.ebay.com/itm/TUNGSRAM-ECC82-12AU7-NOS-NIB/332472352829), but I like Mullard Reissue sound better with AKG, more body to the sound (warmer with better base).
Have people already received it? Do you get tracking?
Same as others, no gain switches and no WM8740 DAC chips in the updated model, came with CS4398 DAC. But both (gain switches and WM8740 DAC) listed in the feature and spec sections on the box :(.
Very odd that they haven't changed it, I am OK with it if the DAC's are equivalent or better which they might be and it is automatically in the high gain mode. Now just have to find the right tube, Amazon Prime here I come babay!
The internals of the TA-01 delivered in the most recent drop. A pair of CS4398's.

Id the XD-05 portable with a battery?
I actually obtained an FX-Audio DAC-X7 review sample and still waiting on official driver but it sounds sweet. I do have a DAC-X6 too and upgraded the opamp but I think the xduoo will be much better than the X6. I read Mullard, Groove Tubes and Gold Lion tubes work wonders in these.
Yes, the XD-05 is portable with a built-in Micro-usb charged battery. It's a bit heavier than the SoundBlaster E5 and much heavier than the E17k. I wouldn't carry the XD-05 around in my pocket but I do move it between rooms when watching movies w/headphones. Maybe some others who also ordered the TA-01 will chime in with their experience with it. All of my xDuoo products work great with my iMac (no drivers req'd).

You made me laugh :-). I don't have this DAC/Amp, but from the spec's, CS4398 is more advanced (better signal processing, filtering, error correction, control - and especially the added native DSD processing bit). Don't know if the new features were used or how well they were implemented though. There are good, bad and ugly engineers out there, but odd's are better if you have better ingredients to cook with.
Sounds good to me, I did a mini review.
What happens if i plug both usb and rca as Input.
Is there really no driver? Can windows not auto install from MS updates?
You gotta download them from their website the usb 2.0 one
Looks cute, where's the pic of the brick!

xDuoo TA-01 vs

xDuoo TA-02? I can't find the bitrate info on the TA-02.

I am wondering if pairing this with HD6XX is a good idea as my PC attached DAC/AMP. Any thoughts?
Well I got notification that it was shipped today. I suspect in a few days we will all know what dac chips are being used. I will decide at that point what I will do, for now the description said Wolfson so I expect Wolfson.

It has arrived. This weekend I will have time to check it out, I don't initially expect much, but I will review it shortly once I've had the time to fully test it.
Great! I hope all is well, this looks great on paper but I'm still a little skeptical given the almost unheard of brand.
I was all set to make the leap until I heard that the CD that comes with the unit has Windows 10 drivers that don't work. Any company that can do that is off the board for me. I am not a techie and do not have time to figure things like that out. Either it is plug-and-play or I don't play

Plug 'n play with an iMac...just say'n ;- )
Driver is on the website.
