Driving headphones properly https://www.audiosciencereview.com/forum/index.php?threads/driving-headphones-properly.5443/

For dongle, Fiio KA11 can produce enough voltage/current for Hifiman Edition XS (well, for my preferred listening level). I think Fiio KA11 is good enough for HE400SE as well, but I didn't test it extensively (just test it with HE400SE a few times as Edition XS is my main driver).

I own HE400SE (stealth magnet), Edition XS, and AKG K371. For planar bass, I would recommend you to try it with headphone amp that can produce >1W of power. I previously use HE400SE with usb-c dongle (Tempotec Sonata HD II). It gave me loud enough volume, but I later found out that...

There is a situation when you do lost "the punch and slam" on your preferred volume. I experience this with HE400se and headphone amp dongle. In my case, I think the dongle I use can provide enough voltage, but not enough current. I found this out when I plug it to a desktop amp Topping L30 II...

I see. I did not test the volume output on mac. I mainly use it with raspberry pi without changing volume.

I own SMSL PS100, and I didn't feel that it sound that bad. So, just perform a simple RMAA measurements and post the result here. I think its performance is good for the price.

Just found firmware for PO100 but not sure should it be applied to PO100 Pro or not. So, I'm checking this forum, and it seems that the firmware is only for PO100. Regarding volume control on Mac, for PO100 Pro, if you switch to UAC1 mode, you could control the volume. If you switch to UAC2...

From my own experience, there is no substantial difference except less low bass. Still, I just listening it normally, not a controlled test.

By the way, if you look at car amplifiers, DSP is quite common feature. DSP is a necessity for a proper car audio installation. For car audio, you don't usually have a proper speaker, you normally have woofers & tweeters that you need to tune by yourself. I have this unit in my car that cost...

I would like to add Fiio to this list. Their K7 & K9 DAC/headphone amp series have parametric eq function (through Fiio mobile app). Fiio K7 bt cost ~$250. I just recheck. Fiio PEQ works only on Bluetooth input.

Just discover Wavelet app from crinacle. You can automatically EQ Hifiman HE400se to harman target without any cost. Thanks for both crinacle and Pittvandewitt for this great app.

Just want to state my intention that I did not post because I want to prove that burn-in works for speakers. I just want to share to others that if you happen to own HE400se and does not like its treble. Before thinking about selling or giving this headphone to others. You could try burn-in as...

I do test the treble peak using Ears chrome extension to boost 8k-10k range by 5 dB on Mac Air speaker. I immediately felt irritating by the peak treble, but I cannot remember exactly that it is the same kind of irritating sound that my HE400se previously produced or not. So, what I can confirm...

I would like to confirm the burn in effect as well. My first impression of HE400se is very good, until it hit the treble peak. It's so sharp and, for me, irritating. I was wondering that if the treble is this sharp and unnatural how could Amir not notice it in his review? This review (I think by...

I have tried Diamond 12.2 with SMSL DO100 & PA5, SMSL AO100 & DO100, SU6 & DA6, Loxjie A30, TEMPOTEC SONATA HD PRO & Aiyima A07. I would say there is no significant difference. The difference in those amp are in bass roll-off (~1 dB), high frequency (~0.7 dB), and THD+N, which hardly audible for...

Would be difficult for me to test on high volumes. I usually have free time during the night after my little daughter went to bed. So, just don't want to accidentally wake her up.

Yes, but I don't have pop noise on PCM to begin with. Only native DSD that has pop noise. My D-6 also have 2 sec output lag using bluetooth. Anyway, SMSL staff told me that they will upgrade it through firmware.

I got this link from SMSL staff. https://www.audiosciencereview.com/forum/index.php?threads/sabaj-a20d-2022-version-owners-feedback.34165/page-4#post-1237845 I follow the instruction and foobar screen configuration, for DO100, pop noise with native DSD issue has gone. For D-6, pop noise with...
