He estimated $399 price. Should be great for my computer room setup.

 

[daniboun]

Impressive for a $400 amp

 

[pozz]

Excellent.

Lead the way, China.

 

[Matias]

Most impressive.

50W @ 8 Ohm?

I will skip this one. Not interested in a garage amplifier for 400$.

Edit: the reduced price pushed me towards being a big fan of this product. I retracted all the negative statements i have made in this post and the following ones.

50W @ 8 Ohm?

Where did you find that information?

Where did you find that information?

It’s in the measurements suite if you scroll down enough.

 

[Zek]

There is no graph of the total / maximum power of the amplifier in relation to the distortion so you can conclude that.
That last graph measured at 50W / 8ohm does not mean that it is the maximum power of the amplifier.

Awesome. Hopefully Amir measures this product in a matter of days.

You can literally see it clipping what do you mean?

Oh you're right, I hadn't seen the clipping graph, it seems to go up to 50 watts and trim

50W @ 8 Ohm?

I will skip this one. Not interested in a garage amplifier for 400$.

Or 130W at 1% THD+N in 4 ohms is quite OK for a bookshelf speaker.

But there is also Hypex NCore NC502MP for $650 and does whopping 600W in the same conditions and still very low distortion and noise overall if you prefer.

Dang that's impressive. @JohnYang1997 got any sneak pics for us?

The amp looks like the PA3s with TRS balanced inputs. I wish I could see XLR inputs instead....
I dont know if it using a power brick or internal PFC smps PSU....

I bet the amp is using the last Merus chips by Infineon (see their site)

MA5332MS - Infineon Technologies

The MERUS™ MA5332MS multichip module offers the same or even higher output power as monolithic alternatives without a heatsink and 50 percent less footprint.

I went through the datasheet, if they use the linked Merus IC, the amplifier cannot compete with Hypex.

It’s just not worth it at all considering this is a garage amplifier with no heat sinking or anything that would allow you to actually draw this amount of power continuously.

With 400$ you can get a class A/B amplifier from Denon with all the necessary heat-sinking, a DAC, a phono stage, remote control functionality with similar power output.

What Denon amp you have in mind?

Or an even closer comparison, at least for U. S. residents, the NC252MP for $500 from Buckeye (which I assume is who you meant, as well).
