Really!!!

Perfect partnership for headphones with low impedance like the SR80i, SR125i, SR325is etc. Incredibly rich warm sound delivered from the gorgeous mahogany enclosure. This is built from a solid block of wood so it is obvious why it is that it is able to offer such a natural sound quality. A headphone amp like none other. This is for a true audiophile!!! Enjoy responsibly.
