Introducing Aethos an incredible integrated amplifier from our good friends at Rega. How does the Aethos make such amazing sound? It employs 4 160 W 16 Amp output transistors per channel, this delivers 156 W per channel into 6 Ω. As well it has a dual mono design using a custom wound toroidal transformer and regulated supplies for the sensitive amplification and driver stages. 

Features & specifications:

Power outputs at rated 230/115 V supply voltage:

• 125 W RMS both channels driven into the rated load of 8 Ω

• 156 W RMS both channels driven into 6 Ω

Note:Continued high level use into 6 Ω may cause the case to exceed 40 °C above the ambient temperature and activate the thermal shutdown.

Headphone output:

• No load 12.5 V
• 32 Ω 2.7 V
• 54 Ω 4 V
• 300 Ω 9 V
• Source impedance 109 Ω

Record output:

• Record output level (with rated input levels) 219 mV
• Record output impedance 560 Ω

Pre-amp output:

• Pre-amp output level (with rated input levels) 840 mV
• Pre-amp output impedance 100 Ω

Input sensitivities for rated output level:

• Input 1-5 and record input sensitivity 224 mV @ 17 kΩ
• Maximum input level 11.5 V (record output amplifier overload point)
• Direct input sensitivity 840 mV @ 50 kΩ
• Power amplifier gain 31.6 dB

Frequency response @ 100 W into 8 Ω:

• Line input 1-5 and record 10 Hz (-0.8 dB point) to 30 kHz (-0.5 dB point)
• Direct input 10 Hz (-0.8 dB point) to 50 kHz (-0.5 dB point)

THD+Noise @ 100 W into 8 Ω: Direct input (Power amplifier only) Typically 0.007% @ 1kHz (measurement bandwidth 22 Hz to 30 kHz)
