Hi all users of the forum.
I would like to build a headphone amplifier, high quality but given the multiple patterns that are on the internet, I do not know which one to choose. The amp that I want to build must be "portable", must be supplied with single power supply maximum 12-15Vdc, and must be capable of driving loads from 55 to 200 ohms. advise you know something? I thank you all for the help given. Have a nice day

Ohms is one part, sensitivity is another important spec - required to determine I, V - along with estimates of desired SPL
very highest sensitivity IEM atually need attenuation with typical 0.5-1 Vrms portable player output
very highest sensitivity IEM atually need attenuation with typical 0.5-1 Vrms portable player output
sure the sensitivity is very important, even if this one did not know how to give a specific value, because with this amp I would, and I do not know if possible, drive properly is for: IEM headphones (with features such sensitivity: 110.6 dB at 1 kHz, efficiency 115.6 dB at 1 mW impedance: 21 ohms at 1kHz) and both headphones studio (characteristics in: 55ohms rated impedance, 200mW maximum input power, frequency range: 16Hz-28kHz, 104dB / V sensitivity)
I can help you find a schematic for this right?
