Should I be worried that I impulse buy things like this like it's a candy bar at the checkout line in the grocery store?

If I'm reading the description right, this looks like it could be an inexpensive version of a FiiO Q5. That makes this a very interesting drop...

When you say you swaped out the amp for the AM5 did you use the stock amp with a balanced cable or 3.5mm. The improvement you noted was it a warmer sound or related to more power?

Steve007I used the 3.5mm only. I'm 90% deaf in my right ear with no ear canal. So I have no use for balanced music. The new amp gave me more bass pretty much. I need me some bass. It didn't seem to improve the warmness of the sound though.

The HD6xx needs about 17mw (maybe a few more for peaks but not much more) to render 110db under 300 ohms. All you really need is 2Vrms. YMMV but then you should be careful with your mileage... with your ears that is...

PeteMtlThe upper limit is to accomodate for transient bursts. It can actually go as high as 120 dB for very detailed music so you must take that into account when calculating headroom. I listen normally around 80 dB so I always set my ceiling for 110 dB+ (I'd rather be covered than not, just in case). Not to mention, the huge impedance swings of the 6XX family and the fact they love gobs of voltage. An LG V30 outputs 2Vrms and it is not capable of pushing the 6XX as intended. Ask me how I know that. I've listened to the 6XX balanced out of some very powerful amps (iFi iCAN, THX 789, etc) and that additional power makes a world of difference. So while you may push them to a reasonably loud volume, you're not providing enough voltage to the drivers to push them with authority and wake the 6XX up.
I'd rather err on the side of caution and not have folks waste coins on a device that isn't made for high impedance headphones and push them towards a unit that can.

Can anyone answer this? Would the Bose QC35ii connect to this Dac/Amp via bluetooth? Or, I would need to use a 3.5mm headphone jack from QC35ii to the Dac/Amp?Anyone?
P.S. Also can someone recommend a nice Dac/Amp with DSD for use on the go with a cellphone and multiple driver iem/sometimes OTE headphones like QC35ii?
Thank's in advance.

Thanks for the info, I also have the bluewave Get, but it doesn't work with qc35 unless I use a 3.5mm cable. In order to have noise cancellation working qc35 needs to operate via bluetooth. I bought GET thinking it will work unfortunately it isn't. I emailed bluewave guys regarding that, they said GET works only with 3.5mm headphone connected.

VAS007The sound quality of bluetooth is limited by its supported codecs. If you want higher bit rates over bluetooth you are going to have to look elsewhere. Last I knew the Bose 35 didn't support aptXHD or LDAC(Sony IP) so you won't gain much by switching devices and keeping those cans. The bluewave Get and Radsone ES100's are both quality BT Amp/DAC's with the former being more suited to harder to drive cans but I find the ES100 no slouch. If you want a device that sends and receives bluetooth the Shanling M0 is a 2-way implementation.

Quite decent specs for the price.
I wonder what kind of parts they're using though.
Anyone know what the sa9123 chip is?
Can't find any info on it. Is it a custom chip?

Well, I haven't fully put its through its paces, but so far so good! It has enough power, but on high gain it still taps out before I do on all my open cans, which vary in impedance (AKG K7XX, Senn HD58X, Monoprice m1060 (what should I get next?)). It does get to full, deep sound before doing so and I can't make it distort, so maybe they left some headroom for revB. Overall it's got enough power for sustained listening and doesn't get bogged down. But if it had any less power, I'd be disappointed. IIRC it's more powerful than the FiiO Q1 Mark II and much less than the XD-05.
It has a similar sound character to my SDAC, which I believe shares the same DAC chip and what I've been using to feed my Darkvoice 336se. I will definitely be spending more time with it, comparing the performance to my XD-05. It's feels about a third the volume and weight of that amp, and I'm loving the XP-2's small size and attractive design. I'm also looking forward to the longer battery life. We'll see.
The USB and analog work well - tested USB on a Mac and my Huawei Mate SE phone, and tested analog from the O2/SDAC's phone output. It was clean at various input and output volumes. But the real reason I bought it was the Bluetooth. Have only tested with my phone so far, and it sounds great. In BT mode it will blow away the amp in your phone, and that's really the point of the thing. And it won't use up your phone battery (it does seem like you can charge the XP-2 from your phone over USB (the charge light comes on) while listening over BT - that's a neat option if you need to charge it up in a pinch). I'm not a super critical listener, but if I really try I do think USB sounds a tiny, tiny bit better in the highs than BT mode. You really really have to pay attention - BT mode sounds plenty good to me for on-the-go use!
I DO think it's a great pocket amp option in BT mode, noting issue below. I always worry about USB pocket use wrecking the charging port of my phone, and it's just easier to use the phone without a wire coming out of it.
The XD-05 is still my favorite portable amp but it's just too big for pocket use. I also have an iFi Micro iDSD BL, but for whatever reason I just prefer the fun sound of the XD-05. And the micro is gigantic - I mostly use it for TV or the rare basshead moment when the XD-05 doesn't have enough power or I want the 3D effect. The iDSD has gobs of power.
One issue: The mode selector should be a SWITCH and not a cheap little easy-press button! The same type as the gain switch would have been perfect!! I've accidentally hit the mode button several times now just picking it up from my desk, and it changes it from BT to USB and kills your music and connection. Not looking forward to how easily that button will get pressed in-pocket! They armored the volume pot properly, but the mode button actually sticks out (!) and could become the Achilles heel of this thing's main use case!
I might have to fashion a shield for it if I really start using it on the go, or maybe I can make it harder to press somehow. The BT does reconnect very quickly, which is nice, but since there are 3 modes with a tiny hard to see LED indicator, it's not easy to put it back in the right mode (especially without looking). If it was just a physical 3-mode switch like on the XD-05 it'd be solid and usable in pocket and ya wouldn't need the indicator. And it'd remember your favorite mode every time you turned it on!
But as it is, it's workable and I'll be using it. It always starts in BT mode and it's just one click to get USB. And since the blue BT light is always on in BT mode, you can use that too (which is good, since as an R/G colorblind guy I can't really use that tiny color-based indicator anyway). One way to put it back in BT mode by feel is to just turn it off and back on again...
Oh, and I wouldn't kick a bass boost switch out of bed! :)

trapnineWow dude thanks for the in depth reply! Really looking forward to using this thing at my workspace at work and home. Good to know about the selector switch but I’m hoping this won’t be a major problem. stoked to hear that the Bluetooth is solid as well. Thanks again!

Yeah that crappy cable belongs in the garbage! How many returns have they had because of their cheapness on those cables I wonder. The XP-2 had much better, little 3 inch cables in the box (one was USB-C).
Oh yeah, xduoo has that module on their japanese site... I saw it awhile back when looking to see what DAC chip this XP-2 has (AKM4452). I agree it doesn't really make too much sense for the XD-05. I was surprised they made it!

I just bought one of the Bluetooth modules, and it is amazingly small -- a lot smaller than you think it would be. It adds a little bit of length to the XD-05, and it sounds great. It is *well worth* the $55, if for no other reason than you don't have to deal with the XD-05's goofy cables that never fit great, and it also lets you keep your phone far enough away that there's no RF static. I was skeptical, but decided to buy it because I love my updated XD-05 (with a Burson opamp), and it is a winner!

Does anyone know what DAC chip this has in it? I read here the USB chip is some 'sa9123' but what's the DAC? Same chip? I'm hoping it's the AKM4490, which they use in the XD-05 and other things...
---
UPDATE: I finally found a site that lists the DAC - audiophonics.fr. They say it has the AK4452, which I believe. It is one of AKM's 'velvet sound' DACs, like the 4490. The AK4452 is the same DAC chip used in the SDAC, which sounds great to me.
So I'll snap this up and give it a try. Here's the summary copied from that site, which sums it all up quite well:
"The xDuoo XP-2 is a portable amplifier and DAC that can accompany you throughout your travels or even at home, to offer you the best of your music. This offers an AKM AK4452 conversion chip supporting sample rates up to 24bit 192kHz, Bluetooth 5.0 with aptX and a SA9123 USB interface."
