The new Racoon SG-300 is a high quality USB DAC/Headphone amplifier/tube buffer. This design allows the tube to be active regardless of which input is in use. The result is great tube sound from your iDevice, Android device, any MP3 player, CD or DVD etc. using the RCA inputs, and from your computer using the USB input. Additionally, the signal from both the USB and RCA inputs is available from the RCA out jacks for use as a pre-amplifier or tube buffer.
This amplifier has huge headroom and will easily power virtually any headphones with ease.The included premium PSVANE 12AT7-T tube provides exceptional detail, superb vocals, smooth deep bass and a well balanced sound stage.
We feel the SG-300 provides the best sound quality and functionality of any similar product in this price range.

Beside using as headphone amp, it a prefect match with the mini power amp Miu Audio MKP-1
