Lol I never really bothered to look at the specifications.. Just thought they were cheap enough to try and they sounded good. Better than the e11 and BH lol
I think how it sounds is more important than what parts that are used by that's just me
I have Tralucent T1 here and JDS C421, T1 being more than x5 times the price and C421 being at least triple, regardless of that I'm really impressed with the sound coming out of this little thing. Like Dmax said the bass is punchy while the mids stay clean and detailed, especially vocals are crisp and have good extension.
From what I remember it leaves amps like FiiO E6 far behind immediately punching up with E11, C&C BH. For my preferences with H-300 its a better pairing than Tralucent T1, though let's not get carried away just yet. It's just better synergy for H-300 because it seems to put the top heavy treble in line and allow higher volume before the rather cold H-300 leans out.
I'll compare to the other amps down the road but this little thing can get up and go with my pure silver interconnect, DX50 and H-300. It's almost like Topping stole a few ideas from C&C namely the foot-print size of BH but at the same time making NX1 thinner. I don't like the power switch position because if you're using a right angle jack like I am with H-300 it gets in the way switching the amp on/off. Straight jacks would be no problem.
I think DMax said he does prefer NX1 to C&C BH and can totally understand how that's possible. I was driving some full-size SHR440 on low gain no problems, switching back and forth between DX50 headphone out and NX1 from line out I think I preffeer the more detailed NX1's forward mid-range.
Another thing is even with H-300 I turn the amp up to about half the volume pot, it's rather relaxed until you lift the volume considerably I tend to listen to H-300 at about 50% 60%, but I'll get a better estimate on that when laying down late at night. When you get to about the last 25% (about 3/4) then it really throws on the power out. (This is in low gain)
I'm really enjoying it and coming from amps like Tralucent T1 that's quite a task and think anyone should be good to go.
Damn Pete! We'll need to send out a search party!
Great impressions pairing with H300! Btw the link provided in the first post from eBay Australia indicates that the price is AUD100+?
*Edit: Just saw the correct link at USD34.
That seller was originally selling for $36.00 then put his price up by $100.Do not buy from him. We're now sourcing NX1 from Deal Xtreme for around $40.00 shipped free.
I actually changed the link this afternoon but you beat me to it. (it's fixed now) Mine took 1 week, 2 days to arrive (from Deal Xtreme)
That's the guy that put it up for auction starting from $10 and I was the only bidder and just as the auction was coming to a close he cancelled it. I was fuming! I could've got it for $20. Then he put it up as a "Buy it Now" item for $75. Don't buy from him. He's a scumbag!

Couldn't help but notice this thread, how good can this $40 headphone amp be? Well I checked out the photos for the Topping NX-1 board and it seems a bit fishy. The specs claim it uses a TI opa1611. The 1611 has 8 pins yes? So why does the chip on the board have 16 pins? It can't be a TI 1611. Anyone?
would it be more likely something like a TI614? don't know much about this stuff

It is most definitely not a TI OPA1611, as that is a SOIC8 chip and the one in NX1 is more like a SOIC16. Plus, they can't use OPA1611 anyway, since it is a single channel. Saying it is an OPA1612 (the dual channel version of OPA1611) will make more sense (though OPA1612 is still SOIC8).
Anyway, I think along the way someone just made up the spec and everyone else just copied them without questioning. The actual spec of NX1 was never published, as far as I know. I can't even find it on Topping official site.
Anyway. it looks to me like a Maxim chip.
Maximum output power | 100mW (RL=32Ω, THD+N=1%) |
Maximum output voltage swing | 8.2Vpp |
Yeah, definitely looks like the specs have been made up! (as on most sellers pages). If it is a maxim chip, would it be something like this solde at mouser?

Anyway, I do agree with others comments stating that it is 'how it sounds' that is most important.
I read somewhere someone was successfully driving 300ohm full size headphones with NX1, thoughts?
Here is the official product page:
Maximum output power 100mW (RL=32Ω, THD+N=1%) Maximum output voltage swing 8.2Vpp

I'm actually driving 250ohm Beyer DT880 right now with it on high gain. About 10:00 on the volume dial for normal listening level. It's a little champ.
