Out of the box, the v2 doesn't sound as clear as the Colorful C3. I hope burning in the device will change that. I believe I read that some people said it become more clearer/better sound after being burned in. The muffled music file has ID3/meta data tags, the clear sounding music file does not. The blinking LED is pretty lame, I know people said you can snip it off with a pair of scissors inside the case, but why did they put it in at all? No electronics device has a blinking LED, especially where it's easily seen. I also don't like the fact that the Hold switch doesn't make it so you can't turn the sound up and down with the knob. Shouldn't the sound stay the same when you turn on the hold switch? But, nope. It still goes up and down. What's the hold switch actually for then? Right now, I'm not liking the Walnut because of those two things, the sound quality is good though. Apparently, the Zishan Z1 (Walnut cousin) may do opamp rolling and allow diffrerent codec's like FLAC, that would knock the Walnut out of the window and into the sea.
