Yes, it is a full step up in sound quality from the NX3S. The NX3S competes against the Fiio A3. The Fiio A5 goes against the Topping NX5.

Why nx5 is better? Spec: NX3s output of 545 mW at 32 ohms and NX5 has 285 mW at 32 ohms? Gain nx3s 8.8 vs nx5 8.9

Thank, you!

I didn't know that there were fake op amps. I am glad that I asked you before buying.

What happens if you get a fake, I pulled a ne5532 from a cheap chifi board and put it in my nx3s and it sounds way better, so does that mean I have a legit one?

The LME49720NA that is in every NX3S amp is fake. I tested the one in there against a few of my LME49720NA opamps I have. The ones I own are all authentic. The sound quality across all of mine is the same. The fake one in the NX3S has a completely different and worse sound. I am not sure what opamp is actually in the Topping, but it is definitely not a real 49720.

Ok, I was talking about if my ne5532 was
A fake or not but you’re saying the toppings have fake chips? They seem pretty good about qc to me

Hello, has anyone use Nx3s with Muses01 here and encounter a radio like frequency sound accompanied by very noticeable harsh static? I just recently got Muses01 and wanted to know whether the Op Amp is compatible with this Amplifier or the Muses01 is defective.
Also the Op Amp Im currently using is Muses8920 and shows no sign of problem though.

 

[536129]

Is your muses legit? Where did you get it

 

[Mori511]

China apparently, order from my local online shopping service (shopee.com.my). It is aliexpress for south east asian country. The seller item claims to be original. And it does look kinda legit with grayish washout logo.
Defect muses01 on Nx3s or incompatibility?

I’ve been told not to buy op amps from aliexpress, so many fakes.

Yeah, its like gacha. You either get fake or there is legit one there. I was lucky with my Muses 9820 and Ne5532. Both works wonderfully in this amp.

Hi @Mori511 I asked a friend who is into op amps, he says NX3s can't supply 9V. So it looks like underpowering going on.

So some kind fellas able to lent me few hands. If it's the case as stated as above then Muses01 isn't compatible with Nx3s. And I just realized that other Muses (8820,9920, 02) are power efficient, hence why I was able to drive my Muse8920.
But.... I also heard some people had used Muses01 on this particular amp, so I'm kinda somewhat in the Impasse now. I need to hear more people to test this case.

SO guys after all what do you suggest for a good swap on the op amp?

 

[tmb821]

Burson v6i dual vivid sounded amazing in it, too bad there is a slight fitment issue...

 

[tmb821]

I run the ne5532p in mine. Also run the same thing in my xDuoo xd05 plus. I like the 5532 I guess.
