I was researching for a budget headphone amp and chanced upon the TOPPING NX1 thread with great reviews. Then I found that @littlemart is carrying the latest TOPPING NX3, so after contacting him, we met up this evening and I bought the NX3 from him.
Here's the spec he shared:

I kindly asked him if I could borrow the NX1 from him for a few days so that I could listen and write a comparative review. He agreed, much to my delight.
2 hours later, fresh from burn-in, I decided to start sharing my brief impressions and may share more over the next few days.
Equipment used for testing: Sony NWZ-A15, Fisher Audio FA-011, SMSL W5 short stereo cable.
Please note that this is the first time I am testing both amps, unlike many other forumers who are too familiar with NX1 audio characteristics. Hence I am offering a relative comparison between the two. In addition, I am testing with FA-011, known to be very open-sounding.
a. NX3 sounds less bright, more tight, while NX1 sounds more airy.
b. NX3 has more body at the bass, while NX1 is less boomy.
c. NX3 is comparatively warmer but retains the clarity.
d. NX3 drives better. I compared the volume to be identical when NX1 is 90% while NX3 is 70%.
e. NX3 comes with bass boost. Enabling it increases the bass range, making it sound fatter.
f. I prefer the NX3 for balance, tightness and bass response. But I enjoy NX1 openness and treble brilliance.
Hope this brief impression can trigger some discussion and interest on this successor to NX1. Do ask any questions and I will try to answer, though I will not be able to describe as precise as other veteran forumers. Thanks for reading!
