New Portable Amp/Dac: iBasso D1 **with updates on the first page** - Page 28

HiFlight, some very good honest input their. I agree with you and I hope you dont mind me using your same principles in giving some positives of the D1. I see a lot of similarites..
1 - still portable by using a bigger case w/beltclip but will probably be best with a backpack/shoulder pack
2 - Equally excellent sound and multiple inputs coaxial/optical/line-out/usb. can be used with an iRiver iHP-140 going iRiver/optical/D1-dac/D1-amp/headphones.(i have not tested this as of yet, i need an adaptor cable )
3 - Long battery life (Lithium Ion 2A 8.4v) good for your average 300-500 charges
4 - User Replaceable battery with purchase of one through iBasso and a little DIY work.
5 - comes with a charger with the amp. (this one may or may not work with the Move)
6 - op-amp rolling. (I'm pretty sure of this hearing Jamato has opened this baby up!) this will give the user the ability to choose the appropriate sound's they want.
7 - very well built / chassis is one of the best I've personally seen.

Sorry for newb question,
I found Move is receiving 16bit signal, while D1 capable to receive 24bit signal,
does that mean, D1 able to upscale to 24 bit through USB?

Took my D1 out for walkies today, and although it was safely ensconced in my backpack, it seemed to appreciate its very first opportunity to stretch its little op-amps and be on the move (pun intended)!

Sourced by my iPod and feeding my Ultrasone PROline 650s, the iBasso with 26 hours under its belt made for already enjoyable listening, out and about, and is clearly beginning to open up a bit.

And, speaking about belts, I've gotta say that, while the included velcro'd leather sleeve may not be the very last word in haute couture, it certainly is functional, providing a nice smooth cushion in between the metal casing of the D1 and my iPod, as they nestle side by side in my bag's special media pocket.

Then again, the D1 seems to be entirely about utility above everything else; it may not win any awards for aesthetic design, but its solidity and quality of construction appear, IME, to be beyond reproach.

For starters, the power button demonstrates no signs of excessive looseness or otherwise undesirable play, exhibiting just the right amount of resistance when pressed to provide the assurance of genuine quality. Fully engaged, the button rests very nearly flush against the front panel of the D1, with just a hair's-width protruding outward to facilitate disengagement.

Personally, I find the recessed 3.5mm mini-jacks to be both attractive and functional (if they're good enough for RSA, they're good enough for me!). The spacing of them on the front panel layout seems just right and they have an authoritative feel when plugging and unplugging peripherals.

Finally, the volume knob, which appears kinda plastic-y in photos, is actually metal (aluminum?) as far as I can tell. More impressively, it displays a decidedly silky smooth travel when adjusting the volume, but, again, it shows no indications of looseness or play that would allow it to move (that word again!) within the confines of a bag or otherwise in the everyday demands of portability.

In my mind's eye, I can compare the tactile delight of the iBasso's volume pot with my limited time spent with various Porta Cordas (though, to be fair, not the M*ve) at meets whose knobs tended to have a feel more akin to twisting the cap off a 2-liter bottle than precision instrumentation (he wrote, sensing the impending lapping of flames ).

But if, as they say, the devil lies in the details, even at this early stage of the burn-in, I already feel happy to be numbered among The Village Of The D1 Damned!

Well I took the plunge and ordered one.

I may be doing that very, very soon. This looks so much more promising than the MOVE, especially with the ability to opamproll

There are many people interested in a portable DAC/AMP with USB, optical and coaxial inputs (15,446 thread viewers since 08-05-2007). There is a market for a device like the iBasso D1, which was not fulfilled by other manufacturers, despite the request for several years from several Head-Fiers. I'm an owner of a HR Overture/Coda (first version of the HR Microstack), AOS Piccolo DAC, the iRiver H1X0 DAP, and always I was waiting for a transportable DAC/AMP (only one device) powered by ion-lithium batteries which I can connect to the optical output of the H1X0/PCDP/portable DVD player and to the digital USB of the computer. I'm very interested in knowing more about the iBasso D1. I will appreciate if somebody can do the comparison iBasso D1 vs HR Microstack (sound signatures). I'm interested to know if there is hiss and/or good synergy with the Shure E500 IEM. How long last the battery using the iBasso D1 as DAC+AMP?
Thank you to all the contributors of this thread.

No hiss with my brief listening last night w/E500's. Its been a very tiring week for me so i don't remember the exact sound at the moment but I can say at that time, it did not sound bad at all. Ill edit this and/or post again with further impressions when i get home..

just an update, according to their web.
It's temporarily out of order... does this mean Out of stock?

They better make more! An interesting point Dexdexter made was about the recessed 3.5mm jacks. As i have seen online the UE super fi 5 pro's have a right angle type jack, i am a little concerned the pin won't reach into the socket enough. Can someone possibly check this for me?

I just plugged in my KSC75s, which have a right-angle plug, and there is no problem whatsoever making the complete connection. Sounds lovely, too!

But the plug of the Superfi looks like this:

Its right-angle is pretty much right after the connector itself,
whereas the plug of the KSC75 is straight after the plug itself:


Judging from the pictures the Superfi might still fit, because of the little round piece after the plug.

But a problem might be the plugs of Westone IEMs (bottom left):


Someone used them with the D1 already?

Here's the complete text now viewable on the iBasso site:

I think it's impressive that iBasso are so diligent in updating their website like this. While they could just as easily have left it as it was and continued to accept orders as they had been, they also would have had to spend more resources answering customer inquiries once the inevitable shipping delays became apparent. And, certainly, no one likes to feel stringed-along and iBasso appear to understand this.

By being so forthcoming in this manner, potential customers understand not only when the next batch of D1s is expected, but also that they can reserve theirs by placing an order. To me, this says a lot about their efficiency as a company and inspires even further confidence.

OTOH, I'm not terribly surprised, either. My experience with iBasso's e-mail correspondence has been excellent. They have always been quick, clear, and responsive (no mean feat for non-native English speakers)...a genuine cut above many vendors I've dealt with over the years, both foreign and domestic (well, when I was living in the States).
