Lotoo PAW Gold Digital Audio Player

Lotoo PAW Gold

When I initially listened to the Lotoo, I wondered if it had as much to offer in the way of subtlety and fine focus as the AK and Questyle players. However, one recording that settled the question for me once and for all (in the Lotoo’s favour) was the intricate and evocative bluegrass track ‘Why Don’t You Go Back To The Woods’ from Jerry Douglas, Russ Barenberg, and Edgar Meyer’s Skip, Hop & Wobble [Sugar Hill]. What especially caught my ear was the effortless manner in which the Lotoo crisply differentiated the attack, timbre, and decay characteristics of the overlapping voices of Douglas’ Dobro and Barenberg’s steel-string guitar—instruments that, as rendered by lesser players, can be very difficult to distinguish indeed. I was also favourably impressed by the Lotoo’s ability tease out the astonishing array of textures that master bassist Edgar Meyer is able to draw from his acoustic bass on this track. At one moment Meyer will explore the instrument’s deep, growling sonorities, yet in the next he will evoke lighter, higher pitched, and more fleet-footed aspects of the instrument’s sound in a manner reminiscent of, say, a mandolin. Through it all, the PAW Gold admirably keeps pace with Meyer’s variegated performance – something that would be hard for amp/DACs of any size or price to do so well.

Over the course of listening for this review, Lotoo’s PAW Gold has become a favourite listening tool for me, as well as a preferred travel companion. I say this because this versatile and accomplished digital audio player is as much at home driving power-hungry full-size headphones as it is in making high-quality, high-sensitivity CIEMs sing. It can literally drive anything and everything well, making it the portable digital audio player for all seasons and reasons.
