http://en.tpdz.net/products_detail/productId=39.html So, this is my new toy to play with from now on (received this morning). This will mainly serve my main measuring dac-amp and bluetooth playback (for iOS/Android gaming or podcast, live news streaming, and so forth). Regardless of well-documented huge hates toward this company (and that A-blahblah guy), this particular product attracted me in some aspects. 1. This is akm topping, not cirrus or ess-sabre topping (now the company name makes sense, doesn't it? lol). Like somebody said before (couldn't remember exactly), it's not very likely to fail with akm chip. Their manual and application guide is so (too?) specific. And dx3 reported to use akm4493eq and opa1612, my bet is topping closely followed reference lpf circuit parameters. Capable engineers such as Schiit or Cranesong may choose different ways though. Anyway I speculate the implementation would be what AKM engineers believe their chip to sound like. Not that bad. 2. Low output impedance I kinda like topping over audio-gd, because at least they don't lie in spec. Many friends might remember S19 r2r dac. Look at what agd claimed AND sbaf actually measured: http://www.audio-gd.com/Master/Singularity19/Singularity 19EN_Specs.htm https://www.superbestaudiofriends.org/index.php?threads/audio-gd-s19-technical-measurements.4305/ (This was enough for me to completely discredit any specs agd claims.) Topping was relatively honest. For DX7S (their top of the line dacamp), they reported Zout as 10 ohm for unbalanced outputs and 20 ohm for balanced ones (shockingly high). http://en.tpdz.net/products_detail/productId=32.html This time around, they claim dx3 has <1 ohm Zout. As a conservative guess, I think dx3 zout is around 1 ohm. Low enough . 3. Bluetooth input I secretly enjoy lots of smartphone games, and bluetooth-connectable dac would be very cool (to me). Extra. Black Like the design. It's sleek and cute. For a tech toy for computer uses nothing wrong in design to my liking. So, how does it sound? Well, so far (8-9 hrs of listening) I kinda like it, at least as a dac. Better than any previous topping dacs I experienced before (d10, d30, d50, etc). Also outperforms cheaper agds (r2r blahblah line). And even sounds a bit better than jot 4490 (pre-lyr3 era) if I recall correctly (as a dac not a combination) and fulla 2 (no idea about which reivision; purchased in Jan 2018). In particular, for speaker uses, it performs more decently than initially expected. But in short, for this budget, buy modi 3  if you're an audio purist. More sonic impressions to come. Footnotes  Of course this doesn't mean their head amp would be wonderful -- and indeed I confirmed they're not. At best, my expectation was "not mega-shitty". Probably sufficient for a measuring amp.  It's a BIG shame that Modi 3 has lost GS 2019 award imho. Convert-2 (winner) is absolutely awesome. No doubt. But it's >$2k. It deserves to its asking price. But modi 3 does way, way, way more than what it asks to pay.
