Basic indicators
Rated power: 100 watts/8 ohms, 200 watts/4 ohms
Maximum power: 135 watts/8 ohms, 226 watts/4 ohms @1% THD+N
 
missed this one first time

i guess at least $999 a pair?

but it goes to show how little people care about A/B these days? assuming these are a/b?


also no trigger
 
What big transformer you have there Mr Singxer :eek:
 
This is a power amplifier with CLASS AB architecture,
which adopts classic circuit design and optimizes the design of each stage.
Adopting ultra-low negative feedback design.

Looks very promising! Any chance to send one to Amir for third party measurements? Estimated price and availability?

This is it, it adopts the class AB architecture.
Not triggered,
All internal work adopts pure analog control.

Thank you for your post.
We have updated the output power

Basic indicators:
Rated power: 90 watts/8 ohms, 180 watts/4 ohms
Maximum power: 122 watts/8 ohms, 202 watts/4 ohms @ 1% THD+N
Ultra low noise level: less than 2.3uV A is weighted, less than 3UV is not weighted @ single ended input low gain
SNR: greater than 140db A weight @ single ended input low gain
THD+N: -110dB A rating of 8 euros and 20 watts;
Damping coefficient: 800 @ 8 ohms

It seems that no one cares about pure analog Class AB amplifiers anymore.
 
different sort of market

i think the market for monoblocks at $1,400 usd is going to be limited

let us say you produce a similar power but much lower quality STEREO class a/b power amp for $700 - even that would be a hard sell on the market and here

funnily enough there's a reasonable interest in the Fosi V3 monos - similar power but $250

i like class a/b - i switched from class d back to my old class a/b but its not a common thing to go back

I don't care much about amplifier class, but that doesn't mean I prefer one either.
Measured performance, build quality and value matter.
I'll be interested in the reviews

So am I. A good amplifier is described by a handful of specs. My current amplifier works in class A at the input and Class D in the power stage....there are many ways to achieve a satisfying result.
 
Really good performance from the looks of it. I don't think there is a lot of competition for super-clean class AB amps like this, maybe only Benchmark? Some people really prefer certain classes, they'll probably be interested in these.
 
Reality check: this is a forum not some sort of dating site. I can't see that posting a public message puts an obligation on anyone to respond to it, even a PM wouldn't do that.
I see you don't understand what good manners are. NRN
