Specially those who have never seen nor examined it.
Look there, but beware there maybe reflections there!

You can measure the output voltage with a $10 multimeter. Very handy for all things audio.Where is the sweet spot (range) with the volume control wheel on Hugo 2? These graphs seem to show an optimal voltage range. I don't have a practical way to measure the output voltage
Depends on your poweramp.Could someone help interpret these results? Where is the sweet spot (range) with the volume control wheel on Hugo 2? My Hugo 2 is in use as a preamp via RCA cables into my power amp then into my speakers. These graphs seem to show an optimal voltage range. I don't have a practical way to measure the output voltage, but is there a way to convert that approximately to the colors on the volume control wheel on the Hugo 2?
Secondly, and maybe slightly off topic, my power amp has three levels of gain adjustment (high, med, low). Based on the answer to the previous question after getting the Hugo 2 output in the ideal range I intuitively expect that I would then adjust the gain toggle to a general desired listening level and leave that gain parked while fine tuning the volume on my Hugo 2. Am I thinking correctly about this?
Honestly it doesn't matter. I wouldn't surprised if it is discrete though.Can someone tell which OPs are used in the Hugo 2?

Chord designed the Hugo 2 without any traditional amping stage (opamp, buffer, gain, etc).
The analogue section is just a single stage amp, coupled via individual resistors...
Ok, thanks! I need some OPs which can drive my Hedd Audio Headphones. Really hard to find something…

Here is the HEDDphone's sensitivity and impedance according to different testers:I don't think there is a portable amp in the world that can drive your Hedd Audio headphones.
On paper!Using my listening volume as an example (80dB SPL Peak), the HEDD would need about 0.1Vrms at 43Ω or 0.23mW
That is $9 Apple dongle territo
I see no reason to.Forget about Apple dongle.
Note that the headphone is quite inefficient requiring nearly 0.6 volts to produce 94 dBSPL at 425 Hz. Due to sharply declining bass response, you need to crank it up much more than this to get decent sub bass response.
They're easily coupled with frequency response to give sensitivity info across the entire spectrum.Sensitivity ratings for headphones is at a single frequency so you can't generalize it too much.
Yeh but that is not a single value anymore. You have to find that value for bass frequencies where you need most power. And if the headphone drops way off in that region, then you need much more power as I indicated.They're easily coupled with frequency response to give sensitivity info across the entire spectrum.
With Hugo2 you get latency!My initial plan was to find an studio interface which can drive the hedds with full potential and just to replace the OPs in my mobile setup because I don’t want any latency.
so don't just assume by glancing at the chart.
