Wow Yin lu Mei S4 really is crazy powerful. But it is really clinical-nuetral, unforgiving, cold in its presentation. But this is a positive thing, as this is compensating for AKM DAC's "velvet" transients.
4 gain levels, 127 steps of volume adjustment, 8 kinds of filters.
Measure size: 81X32X13mm, about 50 grams.
Output Levels: w/127 volume steps:
Single-Ended:
4.5 VRMS at volume-127
2 VRMS at volume-99
Balance port:
9 VRMS at volume-127 (1KHZ sine wave)
4 VRMS at volume-99
THD + n,
SE port 0.0007%
BAL port 0.0006% 1KHZ weight, no load.
It really can drive the HD800S but it definitely is not a synergy match. I can EQ to compensate for its presentation on uapp. (or on apo for pc people) Presentation does well with brass instruments and other instrumental stuff or electronic music. Non-vocal stuff. This thing is really punishing me for owning an HD800S and is determined to use it with only genres like jazz. I own a E1DA PowerDac, the PowerDac is much more forgiving with the HD800S to have it work with more genres. The YinLuMei S4 does really well with nuetral/relatively darker stuff.
Tried this dongle with the Focal Utopia does alot lot better than the HD800S.
EDIT: Also tried using this on a PC with HQPlayer & Roon. HD800S straight out of the dongle sounds great for videos. But using a Roon EQ & Crossfeed and HQPLAYER filtering the HD800S sounds perfectly compensated for music-listening. Really a competent desktop solution for dynamic headphones.
This Yin Lu Mei S4 thing is powerful enough that I feel it could break headphones at max volume. Using a battery is not necessary, I only tested to see if the presentation would change with full power, but it didn't.
Device feels solid, build quality is great. Volume control works in steps, going up/down with a rotation click (not a potentiometer, as this turns endlessly). It also presses inwards to function as a button for the filter-switching.
The small side button on its own is the gain switch.
********
Using my Vision Ears VE8 via the 4.4BAL output there is no hiss. Having 127 steps of volume is nice; I just need about 49 for the VE8. Good volume control for sensitive iem. Presentation synnergy does well with this iem.
Just the HD800S is a picky headphone as usual.
