The HDP-Express II doesn't have balanced or digital outputs and the analog circuits use slightly less "audiophile grade" components. In addition, the front panel buttons are not provided (use the remote control or DEQX-Cal).
The standard version of the HDP-Express II does not have the USB Audio input. This is because it is often used for speaker development and as a slave unit in more complex systems. However, you can add the USB input as an option when you order. It does have four digital and two analog inputs as standard.
The HDP-Express II has identical digital processing to the more expensive units, with the same features and specifications.
Yes! To use with conventional passive speakers, simply connect the power amplifier to the Mid/Full outputs.
