Sound quality: Kanto Yumi speakers had good sound quality. Bass has good impact but is somewhat tubby, a bit pronounced and bass goes somewhat deep. Midrange is grainy, missing a bit of body and is somewhat overwhelmed by the bass. Treble is fairly extended but is slightly subdued, smeared and lacks treble air. What room recovery is present is in the upper midrange and sounds mediocre to decent, with some program material, fine details sound blunted and lack treble air. No significant difference between Bluetooth, wired and optical sound quality. Provides a decent volume level in a large-sized room.
Ease of use: We found the Kanto Yumi speakers to be good overall. Volume control is a large control knob with unlimited rotation, which lacks labeling, index markings and graphical position indicators, but does have a max and min volume visual indicator. Also, the volume control is an unlabeled multifunction control to select sources. Lacks a mute control. Source selection is only fair as the source selector and is an unlabeled multi-function button, which is also the volume control. Although there are LED flashes, there is no distinction between sources when selected until selections return to Bluetooth and both LEDs remain on. Essentially, this means you need to guess which selection the system is making. Wiring Setup: The speaker wires provided are ready for attachment (approximately 6 feet in length, and tinned and split for screw mount posts; no tools required). Instructions are provided with illustrations; directions ensure matched polarity between speaker connections. Bluetooth pairing is excellent as the unit is always in pairing mode when not paired. Unit provides an obvious indication that the unit is in pairing mode as well as when pairing has actually occurred. The remote control is very good, providing volume controls, source selection, mute and some transport controls play/pause and skip but no scan controls.
