@moon-dog kannst du mal posten bitte wo der Magni 3+ kritisiert wird? Wäre sehr Interessant für mich.
Habe den vor kurzem gekauft weil er so gute measurements hat
Magni 3+ for the ultimate expression of an affordable all-discrete current-feedback headphone amp. It’s now seriously a mini speaker amp, right down to the driver stage and Vbe multiplier.
Maximum Power, 16 ohms: 2.8W RMS per channel
Maximum Power, 32 ohms: 2.4W RMS per channel
Maximum Power, 50 ohms: 1.6W RMS per channel
Maximum Power, 300 ohms: 410mW RMS per channel
Maximum Power, 600 ohms: 215mW RMS per channel
THD+N:
High Gain: Less than 0.0013% (-98dB) at 1V RMS into 32 ohms
Low Gain: Less than 0.0005% (-106dB) at 1V RMS into 32 ohms
IMD:
High Gain: Less than 0.01% (-80dB) at 1V RMS into 32 ohms, CCIF
Low Gain: Less than 0.002% (-95dB) at 1V RMS into 32 ohms, CCIF
SNR:
High Gain: Greater than 104dB, A weighted, referenced to 1V RMS
Low Gain: Greater than 115dB, A weighted, referenced to 1V RMS
Crosstalk: Less than -70dB, 20 Hz-20 kHz in either gain
Output Impedance: Less than 0.2 ohms at either gain
Input Impedance: 25k ohms
Gain: 1 (3db) or 6 (18db), selectable via rear switch
Topology: Fully discrete, fully complementary all-bipolar, symmetrical current-feedback design with driver stage and Vbe multiplier, no capacitors in the signal path and DC servo
Protection: Standard failsafe DC power input and muting relay
