Of course. I am located in Croatia
i order often and plenty from amazon (and i'm a dummy without prime because "who knows when i'll order again..." [next month, of course])

The problem Is that there is just one review of this amplifier... Is there anyone in the USA able to send the amplifier to Amir?
Isnt the A8 based on a well known ICE module?

Based on the ICEPower 125ASX2 which is specified by the manufacturer as having a 92 SINAD when bridged and 94 SINAD in stereo.

Yes but it has a preamp stage.
It would have been perfect if they just bypassed the volume control in bridge mode

What would that bring or change?
From a purely technical point of view, the resistance of the potentiometer would then simply be replaced by a fixed resistor.
However, one would lose the ability to adjust the sensitivity. But then a circuit for gain adjustment might be necessary.
Simply set the potentiometer to full deflection,
The supposed 280 mV input sensitivity suggests the preamp adds gain to the nominal 24.8 dB gain of the 125ASX2 module.
F' it, I am interested enough to buy one of these and check it out. Will be here on Saturday.

You can get it from hifi-express, and the price includes tax and shipping. also has a two-year warranty. Thanks
There will be a higher power of the a20a 2022 available to suit the a20d 2022's, also with a BTL mode. But not icepower.
Icepower only used in the A8 and A5.
Thanks for the info. Looking forward to the performance.
Nice.
Already received a10d and wanted to buy two monos a8 but I'm going to wait for the new a20a and use them in mono.
Can't wait.
A10d 2022 seems to be bery attractive unit. Feels very well made and put together. I Iike big screen so I can read volume sitting on my couch.

when will you sell the a20a 2022? will it be class D? can you tell us the technical characteristics?
Yes, Class D amplifier, and I will update the info of A10A 2022 here later first. The info for A10A is done.
That's wonderful

Where can I read it?
A8 arrived today.
Just ran a power sweep and 68W x 2 into 8 ohm at 1% THD+N is a dead on spec as-is the 280 mV input sensitivity with the volume knob at max position which is an astounding 38 dB of gain. 1 kHz power sweep shown below in to 8 ohm dummy loads with both channels driven and volume knob at max. Don't take the lower level THD+N readings as accurate as I am using a MOTU M4 as an input / output device which will have it's own noise / distortion in the mix.
It also does not seem to like any input above 1.6 V which is disappointing because it limits how much you can turn the volume knob down for improved noise performance. Here is a sweep at about 24 dB of gain which results in ~70 W with 1.6 V input. Note the improved noise performance compared to the knob at full volume.
Going to do some testing bridged in to 8 ohms next and then will re-arrange my dummy loads to do some 4 ohm sweeps. Overall seems right on spec which is nice.

Thank you very much for the work and the measures that confirm what has been declared. If I had the chance it would be great if I could do some measurements with bridge mode, which is what I believe many of us use. Thank you very much
