Does anyone know the output impedance?

Found it. ASR reports 4.5ohm. Not good for HPs or IEMs under 36 ohm or sensitive to output impedance. https://www.audiosciencereview.com/forum/index.php?threads/xduoo-ta-20-tube-balanced-headphone-amplifier-review.10118/

Thanks for finding this. Not good for high sensitivity, low impedance HPs or IEMs, but should have low noise floor for high impedance sets. Think this may match decently for ZMF cans, as Zach has mentioned that his headphones sound better with less dampening. Cheers

LDAP is Sony's codec for their BlueTooth (BT) headphones; DX3 Pro does support SBC, AAC, aptX, aptX II, and aptX HD protocols for BT devices. How to Connect: BlueTooth device (plays music) -> BT input of DX3 Pro (for example) -> RCA outputs (Left + Right) on back of DX3 -> Balanced inputs on back of TA20 -> 'Balanced Phone' output on front of TA20 -> Balanced (wired) headphones.

Will the "removable aluminum alloy guardrail" fit my Moka Pot? And if so, how loud do I have to listen to get the water to boil for an espresso vs a latte?

Hello, its actually part of my morning routine, experimenting with different types of music I can confirm that Italian classics works best.

'Wrong power chord' needs to be flagged and corrected before the next drop for shipments to USA. On the positive, replacement tubes (12AU7 / ECC82, matched pair) recommended by the drop community arrived safely and look like they will replace the TA-20 China factory tubes perfectly. I cannot speak to Balanced or any other peformance expectations just yet, due to the power chord situation.

You are very welcome. I however suggest you to steer away from NOS tube on this model, as sources for good ones with low prices kinda dried up.

Ordered new 'gain matched' pair of EH 12BH7 gold pin to try next. Looks like the Drop TRRS 2.5mm Headphone Cable just shipped for the HD 6XX, so I will compare with the following DACs (connected to 'BALANCE IN'):
  • XQ-50 PRO (via BlueTooth 5), May 2020 Drop.. unit has NO VOLUME control..
search
  • DX3 PRO (via BlueTooth 4), June 2019 Drop.. so not v2.0 :-(
Waiting on Hart Cable to ship the 4-Pin Mini XLR (Female) Balanced Headphone Cable for the DT 177X GO, May 2019 Drop.

Who else received the wrong power cord from what they ordered? This is infuriating after waiting 3 months for the thing...

I am running this this on my 02+SDAC (unbalanced) with RCA cables to my Beyerdynamic DT 177X GO's (single ended), and I am getting a ton of interference. Is this the main reason to upgrade to balanced or should is there a problem in my set up?

Thanks @Fayne was able to kill the interference by moving to another wall socket! Sounds fantastic now!

Tubes are subject to RF interference. (You are not counting on glass to block RF, do you?) You should try relocating the unit. Balance connection only break ground loop, which is a constant hum/buzz (you can try moving your AC cord close your headphone cable or RCA cable, that's the same noise I am talking about).

I am currently venturing out of my Schiit magni/modi 3+ . I wanted to try out a tube and also have the option for balanced headphones. However I am unable to find any good information about connecting my dac to it. If I were to connect the Modi 3 via RCA outs to the RCA in of this amp - am I missing out on anything? I don't really want to end up having to buy a separate dac that has balanced out and a tube amp as my first go at everything, just incase I don't like it. For headphones I have HD6xx, Hifiman Sundara and I am looking at picking up a set of closed back cans (which seems to be between the closed dan clark offerings, the meze Nior(I just love the idea of a "fun" headphone) thoughts/opinions?

You could consider a Bottlehead Mainline if it's in the budget.

I am pretty new to "better" audio (I hate to imply audiophile status) so this question might sound stupid. My two sources for music are my desktop PC which has what it calls hi-definition audio but I use a DAC with it and my LG V35 Thin Q phone which has a very good Quad DAC setup built-in. All my files are flac, mostly CD quality but have quite a few 96K and 192K files. With my PC I use a USB connection to my DAC. The DAC has a balanced connection available that I would use to connect to this amp. Is there any kind of cable that can connect my V35 (it only has a USB C and a headphone jack) to this amp in a balanced mode? I really don't want to go through my stand-alone DAC with my phone if I don't have to. Thanks

I like the second option as that appears that it would make a true balanced connection between the phone and the amp. Thanks.

How to make the Xduoo TA20 receive LDAC Bluetooth? Can I use RCA cables to connect the Topping DX3 Pro LDAC to the Xduoo TA20 and connect my headphones to the Xduoo TA20 headphone socket? Please advise. Thank you.
