I got this because the little xduoo tube amp I got on here(ta 03?) Which had super weak specs on paper but was insanely good, especially after I put converted 6sn7 tubes on it
Either way I wanted to give this little guy a go for my laptop, I already have the topping g3 to fit these needs but I like have multiple pieces of similar gear because I have to go bags, I have a studio set up, I have my work stuff. The topping has Bluetooth built in which is great, this can get Bluetooth if you get the external module. The topping is nice and powerful but this has a slightly warmer more fun sound. And with the bass boost function it adds a nice little bit. I'm not sure what the other boost does yet, I can't necessarily hear a tonal difference atleast in the music I listen to but maybe that's a boost for adding an external source.
At the price I got this at, I think it was around 130. Super worth it. I spent 300 on the topping and if I were to choose just one for a laptop dac I would choose this. If you need Bluetooth I'm not sure how much the external piece is but still might be cheaper than a G3
