Project Sunrise... Where to start with this tried and tested beauty? Project Sunrise was our first amplifier design. She has sold all over the globe and has been reviewed, tested and loved for years. She was the first in a series of tweak-able hybrids which simply give so much more vs. the competition. She is what started all this madness for us! If you are looking for an amplifier that can really deliver specifically into lower impedance headphones, then Sunrise III is for you. Overall, an outstandingly musical amplifier with great power.
