First Impressions















After waiting for almost a week to get this thing, it finally arrived today. It looks much smaller than what I imagined it and feels rock solid in my hand, about the same as the C&C BH. 
So me and a mate from where I work sat down and had a musical intermission from doing what we were supposed to be doing, i.e. work. We took some notes on paper as we had our first impressions.

Setup (everything is played at high gain)

  • Motorola RAZR HD and Moto G > Topping NX1 > Takstar Pro 80
  • Listening to "Sundream" by RUFUS (FLAC 16/44.1), "Desert Night" by RUFUS (FLAC 16/44.1) and "Machines Do Care" by Phonat (24/48)

My notes:

  • High Extension/Air
  • Punchy bass - can be overwhelming
  • Warm
  • Some interference and fuzz
  • Volume pot noise

Friend's Notes:

  • Crisp and forward highs
  • V Shaped
  • Punchy lows
  • Mids a bit suppressed

After this I went on to listen to the NX1 for the rest of my work day and more when I got home. 
Initially I did hear some intermittent interference or short buzzing randomly and noise when turning the volume pot but as the day progressed, the circuit got warm, the volume pot got looser and the buzzing and noise stopped. I haven't experience it since.






Sound


This amp most definitely needs a burn in minimum of 1 hour before it starts to sound good. Either that, or my ears needed to adjust to it. It first sounds a bit rough in the highs and floppy in the lows, but after that the lows tighten up and the highs become much smoother. Once you get that out of the way you can actually get to know the amp and it's very transparent. So transparent that I could actually hear the background of the effects of some of RUFUS's samples. High's and lows are very forward and the mid's are not recessed but what it seems like is is that the signature is a tiny bit V shaped, not a lot, maybe 2-3db on both ends. Switching the gain to low setting feels like the frequency response is flattened out but become a little boring. All-in-all the NX1 is a pretty fun amp.

Soundstage


The sound stage is good. It makes it maybe 10% wider than originally. But it suffers a bit from the highs and lows being a bit forward and some of the percussive elements which are put behind you are drowned out. You can hear them, but only if you listen for them specifically. But you cannot hear them at all without an amp. I picked this up by doing an A-B comparison with my Fiio E17 (using only the AUX in, EQ off, 6db gain setting). With the E17 the staging is noticeably wider but the sound signatures a worlds apart, E17 being warm and fun and the NX1 being cold and clear.


This is what I have for now. I'll add more as the journey with the Topping NX1 continues over the next 6 days.

To be continued...




Thanks for the impression. Interesting how you find it sounds v-shaped.

Btw, do you have a dac or dap that has a line out? Because if you connect the NX1 straight to your phone's headphone out, you're "double" amping the sound. The internal amp of the Motorola can have some effect on the final sound out from the NX1.

Thanks for the Impressions DJScope!

Be sure to give the battery a full charge tonight as there were reports of C&C BH dropping performance after multiple hours. I'm trying to pinpoint any drop in SQ with NX1.

I must have got real lucky with my Deal Xtreme Order. From the time I paid it took 1 week, 2 days to my door, though I did order from the rather new 'Australia Direct' site. Actually I was relocated when I put the item in my cart if I remember rightly.

@peter123 You're going through what DMax did, same seller. It will take about a month or so from that tool_nerd seler (bad seller bad!)

Yeah, I've waited as long as five weeks for packages from China on some rare occasions before. What bothers me is that there's no tracking update at all................

I know what you mean mate, gets to a point you start losing interest, though hang in there. I reckon within 10 more days you'll have it.

When DMax purchased his unit as the 'guinea pig sample' from your seller we actually thought it was lost and had forgotten about the thread completely. :o

Whilst your correct if he's got any sense he will be turning the volume of his headphone jack down as low as possible to keep it at a minimum.

 

what's more distressing is that he is using a moto g, which is a great phone but very very cheap and won't have decent internals I imagine.

 

From reviews on here it's probably the best portable amp you can buy for £20.

 

I got mine from here

maybe you guys should order from here?

Unfortunately no. The only sources I have is the Moto G, Fiio E17 which is warm. and the line out from PC. I haven't tried the PC line out yet. Will be listening to it all the day. 

These are only first impressions and will most probably change as I get more accustomed to the sound.

Double amping with the E17 as a DAC actually gives really enjoyable results. Very warm and sweet sounding vocals and it improves the soundstaging ever so slightly.

The Moto G maybe cheap in price, it does not actually skimp out on any good components. The reason other phones are so expensive is because their profit margins are much higher. The only bad thing about the phone is the craptastic camera. The sound quality is actually very good, clear and quite flat when you turn all the sound settings off. When compare to the Motorola RAZR HD and the Samsung Galaxing Note, the Moto G definitely has the cleaner output, and even more gain and frequency extension both ways than the RAZR HD. I'm hoping that my wife's HTC One M7 comes back from the repairers before my trial ends so I can test it on that.

 

And PS. I'm pretty sure you have to have the volume all the way up on the source to pick up every detail. Other wise you lose out on the small parts in the track. Yes you most probably amplify the noise but I've not had any noticeable background noise with the 2 phones and E17 when amplified with the NX1.

Found a seller today stocking NX1 for $42.30 on eBay.

http://www.ebay.com/itm/Topping-NX1-Earphone-Headphone-Portable-Stero-MP3-Amplifier-3-5mm-Rechargeable/271526210088?_trksid=p2046732.c100040.m2060&_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20140107095009%26meid%3D7746990479237228113%26pid%3D100040%26prg%3D20140107095009%26rk%3D1%26rkt%3D4%26sd%3D271526210088

Considering DX you need to make up $40 for free shipping it might be worth someones time buying from above instead.

At least we've found some more stock, possibly quicker turn around times.

I think your DX is different from mine, there's no minimum price for free delivery to Canada.  I think I'll probably cancel my order from DX if I can find another seller close to $40 that ships to Canada (the one posted above does not).

You don't need to have the volume up. It's supposed to be used with a line out signal not an amped signal. The moto g also isn't cheap because of profit margins I know this because I have bought 3 of them as gifts (wife and in laws). It's cheap because it's a cheap phone. It's the best phone in the uk for £100. But it's not the best if you have £150 to spend (Nexus 4) or £250 (Nexus 5).

 

It has a crap screen in comparison to those phones as well as RAM, camera, etc, etc.

 

Volume should be low as possible to exclude the built in amp as much as possible.

 

http://en.wikipedia.org/wiki/Line_level

 

Stick the volume on like 25% and use the portable amp.

 

The nexus 5 cost me £350 iirc at launch so 3.5 times what the moto g costs and it's built in dac/amp produces a lot of noise and distortion when you use the top 3 notches on the volume level bar.

 

Therefore on a phone which costs 3.5 times as much and has much better internals has a bad signal on the top 3 notches I wonder what a phone that costs nearly 1/4 of the price sounds like.

 

The moto g is great for £100 but in no way should it be used in a test of sound quality for a portable amp unless you have the volume on it turned low as possible to mitigate the built in amp.

Ok thanks for the info. I've been using the NX1 with the PC line out most of the time. It sounds a little bit clearer. I'll be doing the rest of my review once my time with the NX1 is up. So far my initial impression has changed. With much more further testing with an actual AB switch that works better than just changing the cables across I've been really surprised at the findings. But that will come in my review.

 

Like I said earlier. The Moto G sounds better than the SG Note GT-N7000 which costed 4x more than the Moto G, but that is an ear comparison. I wonder if there are any RMAA tests done for the Note, N5 and the Moto G.
