The Nano looks like it will weigh a brick. In reality it doesn’t. it is surprisingly light. Weighs just as much as my phone. It is a bit thick, but its not massive. The unit looks beautiful in the stealth black finish . The lettering in the back is a bit hard to read since its also black. You have to hold the nano in a specific angle for the light to reflect just right to see what is written
wow this definitely changed the way some of the tracks sounded to me. It was mostly heard on my jhaudio 10x3. Plugging them into just the direct port gave the slightest hiss, but after plugging them to the iEMatch it was like day and night. The background was pin drop silent. It gave a real empty feeling when the tracks had silence in them
To be honest I tried a lot to hear the differences between the two filters. I was not able any difference, maybe it is just my ears. I left it on measure for the majority of the time after the initial switching around to hear the difference.
Murder One – Metallica
hd6xx - warm, not as crunchy as I would like it. the amp has plenty of power to drive it. I was able to tell the different layers and separate them
jhaudio - warm, same as the hd6xx not as crunchy I would prefer. plenty of power to drive it. the iem match does make a difference. Was able to tell the different layers
AFO – it doesn’t like this song through the iDSD nano. It sounds cluttered and underpowered.
Nuforce – I had to run these on the direct port. It did sound much better than driving it with just my phone, but it was not a lot better than how it sounded with the hd6xx and JHaudio
Spanish Harlem - Rebecca Pidgeon
jhaudio - iemmatch made the silent backgrounds as Silent as I have ever heard. the female voice and the voilin sounds beautiful. Made me listen to this song on repeat atleast 5 times. it sounds very musical. can hear the instrument layers very clearly. from the bass line to the marracas. Beautifully matching. The imaging was very nice. I was able to pick out every instrument
hd6xx – not as musical as I liked it on the jhaudio 10x3. It is missing the coherence on these. The piano sounds too warm and kind of muffled. The background is pretty silent. The female voice comes out beautifully. Just a tad warm for my taste. The imaging was there. A bit cluttered
Wayfaring Stranger - New Appalachians
hd6xx – the female voice comes out beautifully again. The bass line also is very nicely presented. Kinda missing the umph, but that might be the headphone also. While the imaging was nice. I felt like a layer of music was missing when comparing to listening with the jhaudio 10x3. Other than the nano performs this song beautifully
jhaudio – pretty much everything was delivered perfectly to my ears. The Nano performs amazingly well with acoustic music.
Nuforce – the sound was too warm for me. It wasn’t muddy or bad. I would have liked a bit more treble and mid range. The bass was overwhelming
Oneplus 5 vs iDSD nano – the nano definitely has a lot more power for headphones. It also sounds cleaner with better soundstage and imaging. It is definitely worth paying the $200 for this.
Shangling M3s vs iDSD nano – hands down prefer the nano. They both seem to have the same amount of power output. The nano might be a bit more powerful, but the nano sounds transparent and neutral compared to the M3s. The m3s is too warm for my taste. The nano has better soundstage than the m3s
NFB 11.28 vs iDSD nano – these two are not exactly in the same class. The NFB is a very powerful amp. The nfb is much more transparent and also sounds neutral. Maybe the tiniest bit of sparkle. The nano sounds a bit warm when you compare it to the nfb. While the nano has a good soundstage, the nfb beats in a very noticeable way.
While this is a portable amp/dac it does have the power to drive the hd6xx very well. It does not sound as open on some songs, but other than that this performs very well. Boy does it perform like a beast with my jhaudio 10x3. JUST WOW!! The two are a perfect match. With the nuforce x massdrop while it was better than just driving it with my phone I don’t see myself carrying the nano just to drive these. It is not the Nano’s fault. The iem is just not on the Nano’s level. It seems to bottleneck the dac/amp. I highly recommend this to anyone that wants powers their portable headphones and iems on the go. I might actually buy one myself.
