In summary, this is an awesome sounding compact all in one unit. It will take the digital output from any basic CD, DVD, or Blu-Ray player and transform it into excellent audio without a lot of fuss. It has good jitter control, a transparent USB input, and enough power for most speakers in most rooms. The headphone amp is decent with low impedance headphones but excellent with higher impedance models. An excellent choice for someone needing a compact all in one unit.
