Summary: This showed up broken. I've since ordered the DTA-120, which is working. If this was how the DTA-100 was supposed to sound it would've been a good product, if it was capable of being turned on.
Summary: Been using this for a month or two now, and am constantly amazed at how 'clean' this little amp sounds! Both on headphones and on speakers (Polk Tsi100's) they are perfect for use in my small bedroom.
