Sound quality: Wren Sound's V5US had very good overall sound quality. Bass has good impact but is prominent and boomy and goes somewhat deep. Midrange is fairly even but also a bit gritty and soft, and the lower midrange is overwhelmed by the bass. Treble is extended but is also prominent and sizzly. Does a decent job of recovering room ambience but is rough, a bit congested and lacking in detail. No significant difference between WiFi, Bluetooth and wired sound quality, except that Bluetooth has slightly more prominent treble and is still sizzly. Provides a decent volume level in a medium- to large-sized room.
Ease of use: We found the system's ease of use to be very good overall. The Wren Sound V5US connecting Bluetooth pairing is easy. WiFi/Airplay: requires app installation and following the on-screen instructions, includes leaving the app to go to settings menu of pairing device to select Play-Fi speaker in WiFi network, then returning to app for completion of steps. DLNA: Not directly discussed, but instructions for setup are implied via PC-network setup in manual; it's not ideal but it does automatically setup. However, it's not indicated in WiFi setup. The provided remote control is very good. The console controls are decent, but are positioned off to the side of the unit.
