About the EVO 300 Monoblocks
The PrimaLuna EVO 300 Monoblocks are EVO 300 Hybrid Power Amplifiers operated in monoblock configuration, combining a tube preamplifier front end (six 12AU7 tubes per chassis) with a MOSFET output stage for a hybrid design. In monoblock mode, each unit delivers 220 watts into 8 ohms and 300 watts into 4 ohms, offering the smooth, tube-like character of the 12AU7 front end with solid-state current delivery and grip. In stereo mode, the amplifier delivers 100 watts per channel into 8 ohms and 150 watts per channel into 4 ohms. Features include both RCA and XLR inputs, a frequency response of 10 Hz to 80 kHz (+/-3 dB), THD of 0.2% at rated power, a signal-to-noise ratio of -105 dB (A-weighted), and PrimaLuna's overbuilt power supply and protective circuitry. Each chassis weighs 68.3 lbs.
