REVIEW | HEADFONIA.COM
“… Lotoo has a very unique approach to digital audio players. With their pro-audio background, it doesn’t come as a surprise that they have opted for a super neutral signature for their top of the line music player. At the end of the day, it is the ground for their customers to build their own sound on, and what better signature to have than a reference one?
The PAW Gold Touch brings a few features to the table which we haven’t seen in any other portable player, at least none that I know of. If I’m correct, it’s the very first player to come with a built-in Sample Rate Converter and enabling this one, makes a noticeable difference in sound.
I can only imagine how long it took Lotoo to code their own firmware for this unit, and I am deeply impressed by how far they have come with it. It’s one of the most enjoyable units out there and I tip my hat to the engineers who made it a reality.
Hats off to Lotoo for one of the best audio players in the current market. The Touch gets my personal stamp of approval and goes on to the list of Best DAPs.”
