Headroom Notes
iFi never prints a headphone voltage for the Uno, so the number here comes from the 300-ohm power rating, where the amplifier is voltage-limited: 39 mW into 300 ohms is 3.42 V. At 32 ohms the same amplifier manages 211 mW, which is 2.6 V — it runs out of current, not voltage, on low-impedance loads. Output impedance is not published at all.
Was im Datenblatt tatsächlich steht
Wörtlich von der Herstellerseite zitiert, mit dem Datum der Prüfung. Wir behaupten das Gedruckte, nicht die Absicht dahinter.
«OUTPUT 2V max.»
The row says OUTPUT 2V max. without naming which output, while the row two lines below reads RMS OUTPUT POWER, Headphone Section: >=211mW @ 32Ω; 39mW @ 300Ω. Those power figures require 2.6 V and 3.42 V respectively, so 2 V cannot be the headphone ceiling; 2 V is the standard level of the RCA line output. Taken as the headphone figure it would understate the Uno by more than 4 dB.
