Customer Testimonial

The prices are the best by far, and a wide selection of good stuff. Not to mention the fast shipping. I ordered my speakers wednesday morning, and had them in my hands thursday afternoon. You just cant beat that.

I would highly recommend this site to anyone looking for anything audio related.

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.
