I only have PCM. In fact, I listen to a lot of spotify (non-premium) while the rest of my collection are Flac rip from my XRCD's. Very enjoyable to listen too (ok, depends on the source too ... bad recordings will sound bad still). lol

But if you want to listen to a bad recording, you can knock off some of the hard edges by engaging the Minimum Phase filter.

The micro iDSD continues to impress here. In the past and with certain CDs in my collection I have become aware that I am gritting my teeth as I listen to them. This no longer happens since the arrival of the micro iDSD. It is a very smooth performer with a very detailed and well separated treble that isn't harsh (unless the recording is harsh). The sound has great depth and seems to reveal layers of sound I wasn't previously aware of or at least was less aware of. I should add that I use the 3D function nearly all the time now. It certainly sounds different to the Audiolab (more later when it's fully burned in) but is giving me 'WOW' moments on a regular basis just like the Audiolab does.

Normally my LSR305 monitors are connected to my Schiit Lyr but for the last few days I had my micro directly connected to my LSR305 instead of the Lyr. The sound is more direct, sharper and the soundstage width is a bit more diffuse as with the the Lyr. The 3D switch has more of a dramatic effect on the LSR305. It is more of an in you face type of sound but also have greater front to back depth. The 3D effect on headphones is more subtle and it is very headphone dependent and so far not as useful as with the LSR305. Still have to try other headphones. I almost never use the bass switch.

I'm still burning them in but fwiw - IMO - to my ears at the moment.. after 3 days of listening in my environment with a brand new LCD-3(f).

 

Micro - it surely is punching way above its weight class. Its fantastically honest sound that works well with good recording. I find it losing control in 16/44 recording at upper mids to lower hi. Sound stage is incredible for device at this price range. It makes me go wow many times with its clarity, truthfulness of the recording and very good sound stage with my LCD-3(f) which is still burning in. What I don't like is too many settings, too many things to do with the device. I like to enjoy my music and not be bothered so much with the device's settings, having to turn down the volume in between each DSD files, etc. I want to enjoy my music. But that's just me. Also I don't understand why they have male USB for charging and don't provide the 'male-male USB' cable in the box. Most universal adapter are male-micro USB or others. Some how the connector for data does not charge the device for me (I plug the USB then turn on the Micro). So I had to go buy a male-male USB connector to charge it. All in all, I feel its a hassle and feels a bit that Micro is a toy product with great sounds. I can see many will like this, but I'm getting too old for it. The 3D sounds I didn't enjoy so much. When I switch it off, I enjoy the music much more. Its great product for it's price range and way above. As mentioned, it make me go WOW but my feet are not tapping.

 

Hugo - All the above in sound quality but more refine, no messing around with settings. Cross-feed is more natural and I enjoyed it in low or med settings. At the end of the day, I can listen for hours and hours with my head bobbin', singing along and my feet tapping.

 

Again, this is my personal impression.

I think when you are talking about the male-male USB cable for charging you are talking about the USB input on the side of the Micro iDSD.  Am I correct?  That is actually an output to charge another portable device.  The blue USB cable you are using to connect your laptop to the iDSD is the cable that charges your device.

Yes, but the blue cable is not charging it for me. I connect the USB then turn on the device which mean it should charge it, but it does not.

Only when I use the USB on the side, it will charge.

If the LED doesn't illuminate that means the iDSD is charged.  I just tested this myself.  The LED turns blue if the battery is not fully charged.

The LED does not illuminate with blue USB when I plug it in to my universal charger or attached to my Macbook Pro, yet it has no juice. So maybe my unit is defective.

Still have not decide if I want to keep it or trade it in for something else.

Hmm...maybe it is defective.  How did you get it to work earlier?  Did it come to you partially charged?

Huh?

 

I use the black cable with the head connected at 90degrees angle for charging, not the shorter balck cable, nor the blue cable. i think you must have misplaced a cable, as I got 3 USB cables in the box. No pops either, even when switching from DSD256 and other rates and PCM.

So I'm a bit confused about the 24 hour charging rule also.  I got mine today and I plug it into the charger and the blue light stays on for about a minute, then turns off.  I assume that means the battery is charged....but why are they pushing the 24 hour charge if it's not necessary??

 

How long did everyone else's initial charge take?

My charging took about 6 Hours,but I left it on for 24 Hours anyway... All the above links say untill the Blue Light goes off...

Battery charges in two way, voltage and current. First it charges mainly on voltage difference, then it goes into a current charging phase once it is near the max upper voltage limit. A smart battery charging circuit will usually detect how much voltage and current are being used and switch accordingly to ensure the battery is getting the right voltage / current and so it won't over-charge the battery. But that doesn't mean the battery stops charging all together. Usually in most case, the battery can still take just a little more to be actually full, but the charging circuit won't know it as they are usually not that sophisticated in design. I'll assume the 24 hours recommendation on the first charge is to help to 'recondition' the battery to make sure the chemicals inside the battery will get fully activated in the first run (a.k.a. getting an actual full charge instead of what the charging circuit thought it has). In other word, the blue LED is likely acting as an indicator where the voltage charging phase is over, but may not be that accurate on the current phase, thus the advised extra time to make sure a full initial charge. It probably doesn't actually need 24 hours but I'll think iFi is just being extra safe for a longer number.

I use the blue USB to connect and it worked fine. On my listening session yesterday, I tried turning the Micro on before plugging in the USB to use the battery to see if the sound would be cleaner.

After which the battery ran out. So I take the blue USB and plug it in my universal USB charger for about 12 hours (when I plugged it in, the blue light come on for couple of second and goes off).

After 12 hours I checked on the unit to find it had no juice at all. When I plug it back to the computer it will have blue light and blinking red, which I assume its low on battery still.

 

So the blue light indicator does not really work (or work but I'm just clueless). Does anyone know if there's a battery level indicator I don't know about?

Since the blue light always go off after couple of second, I have no idea if the unit is charging or not.

Sounds defective.  The blue light should flash for 3-4 hours for a full charge, not a couple of seconds.  When you tried to run it on battery, it ran down immediately, indicating it is not charging, only running via USB power.

What software are you using for playback and what settings? In Audirvana Plus, it only pops when I use DSD over PCM Standard 1.0 setting. In conversion to PCM, it will not pop.

 

Actually, the 90 degree cable is mine, not from Micro.

These were my unboxing photo.
