Sound QualityThe Harman Kardon Citation 100 has overall good sound quality. Bass has good impact, goes deep but is a bit prominent and boomy. Deep bass may be prominent with some program material. Midrange is even but is a somewhat hazy, soft and bit grainy. Treble is extended but is somewhat subdued and smeared. Does a decent job of recovering room ambience and is somewhat congested. There is no significant difference between Wifi and Bluetooth sound quality. Can provide enough volume to fill a medium to large sized room.

Ease of Use
Overall ease of use of the Harman Kardon Citation 100 is very good. Wireless setup: Setup requires an app downloaded to a device or device connection, easy and intuitive - need instructions (may be included in app), may or may not involve inputting WiFi network password, and account setups. Console controls: Volume controls are prominent +/- with graphical indicators of volume level which are non persistent and easily repeatable via verbal commands and easy to actuate. Also, generates a tone with respect to the level selected with discrete volume changes with the physical controls. Audio mute: Unlabeled multi-function button, no indication when it is engaged. Microphone mute: Well marked, well placed, clear indication when it is engaged. Source selections: Requires app to be installed, app installation is straight forward. Once app is installed switching between inputs requires selecting the -cast- icon in a 3rd party supported app. Fairly intuitive but subject to 3rd Party implimentation of cast selection. App remote: Volume control not obvious due to poor placement. Mute: (Remote) Dedicated control but the marking is not the most obvious, clear indication when it is engaged. Voice transport controls: Natural language control of transport (Play/Pause/Skip/Mute), volume controls and source selection was easy and intuitive.
