Now I have the HE 4XX. It is good but I feel missing an appropriate amp.
I don't think my FiiO Q1 MKII or FiiO A3 can produce enough power for it - specially for Bass.
So, need to upgrade the AMP.
My restriction is that I do not live in a fixed home and my power source varies from 100V-220V.
So, I need either USB powered AMP or an amp with 100V-240V power support.
It also have to be portable (not desktop size).
Budget should be limited to USD250.
Do anyone have any recommendation?
How is FiiO A5 and iFI iCan Nano?
I have both of the above dac/amps and agree that can't drive these properly but the A3 on High Gain can just about be OK. The more power the better for these cans so I would recommend a Mojo or a iFi Micro BL. If these are beyond your budget then a powerful amp like the Cayin C5 or A5 at a pinch.
Are you using the balanced out on the Fiio Q1? I find it has plenty of power for these cans in a more mobile setting and the bass switch is a very nice feature. Oh one more thing your input device will have a large impact if you aren't using the internal dac. My pixel phone has a lot less input than my Fiio X1 gen 2 and makes a huge difference.
Thank you very much for your reply. I do not have a balanced cable for HE 4XX. But I understand what you mean because I use other balanced IEM. Do you have any recommendation (under $100) for a HE 4XX balanced cable?
My source is mostly its internal DAC or AK Jr.
Yeah I bought a set of HI-4-B off of amazon but I do have the HE 4XX that has the 2.5mm connection at the cans.
I am looking for a balanced cable for my HE4XX but can't seem to find a cable that terminates to 3.5mm at the cans. Wonder why HiFiMan changed the design from 2.5 to 3.5mm,
Thats a tough one without rigging something up or getting them custom made. Really I only spent a few minutes on google though.
I have the iFi Audio nano iDSD Black label DAC/Amp and it drive the HE4XX without any issues. In fact the combination is excellent and this is the combo I use for majority of my music listening. My sources are my Dell XPS laptop, Onkyo DP-X1 & my iPhone XS.
Thank you for your sharing. I can see it. I also think iFi sound signature goes quite well with HE4XX. I recently purchased iFi xDSD and together they are fantastic. Perhaps for low sensitivity, I just need to use 70%-85% volume to get a decent loudness. And initially it gave me some feelings - is it safe for my hearing? May I ask this silly question - how much volume you need to use typically with iFi Audio nano iDSD Black label? Thanks again.
I recently bought the iFi Nano BL and a Topping A30. The nano can itself drive it very well with the knob at around the 1 o clock position. But the A30 can actually make it sing. The difference is really noticeable. Mids come forward, bass gets better and highs smoother.
