The D1 dac has gone through changes from being too bass heavy, imo, to a more uniform sound but still a little too much bass with my RP-21's but fine with my 650's and bamboo earbuds. It also sounds fine with the Portapros. The upper mids and lower high frequency needs some improvement as cymbols, the sound is a little white and less brass. The dac needs more time as even my Monica II needed a few hundred hours. The Monica II is smooth, great bass response and very open and dynamic. I use Blackgate caps throughout the Monica and she likes it.


For those who like bass the D1 does this.

I should mention that the combo is very quiet. I have turned the volume to max and hear very little (with no music :^) ).

Where is the AD8397 on the iBasso? Jamato says it uses NE5532, and I don't see anything that looks like an AD8397 on the board at the moment; maybe I'm overlooking it?

There is no 8397 in this amp. It has a AD823 as the dual opamp and the buffers are the NE5532.

Thanks for all of the info & pics so far guys. I don't really even need this amp and I want one...funny how that happens a lot with me

It seems to be a very good value...everything needed is included.

Did someone say bass

I was out "mobile" today with the PortaPros and the D1 controlled the bass very well. I got nice imaging and the sound was to the sides and in front of me.

Happy day today!! I received my D1 via UPS this morning! I just now got a chance to fire it up and spend a bit of time listening to the USB DAC as well as the optical input from my iRiver.

Initial impressions are very favorable. Quality of construction appears first rate. Sound is very nice for the initial listen. I concur with John that the upper mids and lower highs seemed a bit bright, especially with the optical input, but it didn't take very long at all to tone down to a more natural level. Tonal balance and soundstage seem quite nice at this point.

I cannot tell a great deal of difference, if any, between the DAC performance of the D1 and Move. Both sound good. It may take some critical listening with a variety of music to really differentiate between the two. Interestingly, the iBasso uses the same 12vdc input plug as does my Move, so the regulated power supply that I have for the Move is doing double-duty. The AC adapter supplied with the iBasso is a nice unit, but I measured the output voltage to be 12.17 vdc. The recommended voltage for the Move should be limited to 12.0 vdc, so I will use Jameco adapter for both, even though the 12.17 would surely be acceptable for the Move as well. It just saves me having to deal with one more adapter.

I did try feeding the optical out thru the aux in/out of the D1 into my Reference and the results are superb. I think the Reference is going to be very difficult to surpass as far as soundstaging and overall sense of realism.

I keep reminding myself that all of these components except the Move have only a few hours of powered life so far!

Although the D1 cannot really be called a pocket amp, it certainly falls within the realm of portability. The flexibility of all the input/output options place it firmly in a niche that no other piece of equipment in this price range can begin to match.

The sound as fed thru the optical input really leaves little to be desired as far as any reasonable expectation of quality audio. I can forsee really using this a lot. Makes me really glad that I held on to my H120. With the options that Rockbox provides, as well as a means of utilizing the optical output, I am set for many hours of enjoyable listening.

Well done, iBasso!

Ron, are you using the D1 with a pc on usb out or a Mac? I can't get mine to work with my Mac and wonder what I may be doing wrong but it should be a plug and play with no drivers needed for chip used.

I have been carrying the D1 everywhere with me and don't find any difference in size when compared to my Reference and Monica II dac with a Sony portable using the optical out. I am enjoying the D1 quite a bit and love all the options. I concur about the Xin Reference but the amp in the D1 is no slouch.

Time for a few more!

Congrats, all!

Nice pics too. Can't wait to hear your sonic impressions (after burn-in, of course).

When you connect a USB out to the Mac, you must go into system preferences: sound and select output. The DAC should be listed, and you've got to select that. Make sure your phones aren't plugged into the Mac.
