Yesterday got my Ibasso DC05. listened whole day plugging those.

Noticed few things:
Performance is better in PC, just plug in play. Synergy, vocals, thumping bass everything is there, very much enjoyable.

Playing DSD is a hassle in windows, can't get foobar2000 working(any suggestions or tutorial to do it properly will be helpful), anyway installed JRiver media center(only 30 days trial after paid), works flawlessly and was able to play native DSD (some test files and 1,2 songs found on internet), FLACs (possible with most players though) easily. didn't find any noticable difference with the pair of devices I have.

But with phone things are different, first thing for most streaming apps don't use the external DAC. For my smartphone I found except loudness there's nothing to notice in sound quality unless I have local FLACs and using HIBY music player, otherwise that I found streaming apps are not using the DAC, the synergy, sound signature was not there at all while using with phone. Phones equaliser, volume adjustment, adjust sounds to earphone... options are working with DAC plugged in, which should not work with DAC in the first place, so thinking that phones DAC is processing the audio and just bypassing it (a wild guess, because sound signature is literally same to my phone just a bit louder).

Power usage wise didn't find any problems, not so power hungry.

Sound signature is mostly neutral and a bit forward I would say (headphones which I have is nowhere accurate sounding, but enjoyable- OneOdio Pro50's ), bass is tight, with some bass heavy headphones it can rumble your ears, and when the time of high frequencies came they shines, the sparkle is enjoyable not painful at all, Laal ishq by Arijit , is soo soo enjoyable.

bought it from Headphone Zone, and thanks to them for delivering these in two days (i live in a remote area).

Devices- Redmi note 10 PM, ibasso DC05, OneOdio pro50's.

4th picture: controls which I talked about above.

Something to add-on, and found while extensive use is that it heats up more while using with phone rather than PC, and suggest to use it with PC to bring the most out of it. And yes it can make a difference in your normal earphones/headphones too.

I don't have prior experience of individual DAC, but after pairing IBASSO DC05, with my smartphone and Audio Technica M40, i noticed significant Improvement in overall audio, even seems it unlocked some more frequencies and i am able to hear some more instruments in same songs i was listening earlier, dac is quite compact to carry, thanks headphonezone to bring such good products.

Ibasso 5 + Maze Rai Solo + LG G8X... Whatta perfect combo when u play WAVs, that I can Feel in Recording Studio.

Kudos to HeadphoneZone🎧

I've been searching for a portable DAC dongle for my Oppo Reno 2F for some time, because I have always felt that my phone's inbuilt DAC is nothing but shit, since, I mostly listen on my PC using Topping E30+ Edifier R1280T speaker, the difference in sound quality when listening on my phone is most noticeable & unacceptable to me. I didn't have much option due to budget constraints. I selected Shanling UA2 primarily based on the reviews on HPZ; but later I changed my mind and shifted to iBasso DC05 due to it's dual DAC implementation & very good reviews on online forums & I thank myself for my wise decision. I have paired it with my recently bought Moondrop Chu & the outcome is phenomenal. Yes, 'PHENOMENAL' is the right word compared to phone's internal audio. Each & every instruments sound clean & seperate from each other, it gives you a feel of being present right in the concert hall & the performances are going on in front of you. Vocals are little bit forward, bass is very good and punchy and it compensates for the lack Chu has, thus making it a perfect pair with Chu. Treble is good but not ear piercing. I would advise you to use iBasso UAC app for fine tuning volume alongside phone volume button. Many many thanks goes to the HPZ team for bringing this marvellous product to their store and timely delivery. My search for Desktop audio solution had long been ended with the purchase of Topping E30 (from HPZ) and now the hunt for portable audio solution also meets it's end happily. Or does it? Who knows! 😉

Few months ago I bought UA1 Pro. Soon I realised it was a big mistake. The vocals were absolutely bad and rough, with overly boosted treble, sharp ear hurting.

Ibasso dc05 has the same dac chip x2. I was afraid it may suffer the same problems. When I first started to use it, this too had sharp treble but soon I found as the dc05 heated up considerably, the sound signature started to balance out, burn-in helps.

Dc05 has a U shaped sound signature brighter than neutral with more bass punch than neutral too. Vocals are excellent smooth, clear sounding. There is a simulated wide soundstage. Iems are best for this dac dongle, especially IT01X.

Overall Ibasso has done an impressive job too tackle the shortcomings of a ESS chip and made a impressive dongle. Still there is sharpness in S sounds.

No compatibility issues with windows or Android. For Android use of neutron player or having super user access is necessary to bypass Android limitations.
Cons:- Its time for picking faults. When paired with hifiman headphones, we can clearly hear noises in high treble. Accuracy in treble beyond 10khz is poor and harsh sounding. Bass control is bad in headphones with high drive current. DC05 is clearly not meant for premium headphones. Iems sound excellent though. In daily usage, both for Android and windows software volume control is used unless premium softwares with uac2.0 built in is used.

Overall I would say, after using various dac and amps this dac dongle is unbeatable at this price range.
Synergy info:- Ibasso IT01x, Moondrop chu. Excellent balanced sound
