Yes. The main interesting thing is the power level of each amp. Do they stay very close to spec?With mono block amps using dedicated power supplies there will be zero crosstalk from the amps.

Interesting question. The gain(s) of each amp should be very close I think. Perhaps somebody else can chime in and confirm that or give more information.Yes. The main interesting thing is the power level of each amp. Do they stay very close to spec?
What is O-NOORUS D1?
It should stay same or close to what's found in measurements/testing here if fed with same separate PSUs.Interesting question. The gain(s) of each amp should be very close I think. Perhaps somebody else can chime in and confirm that or give more information.
I'm not sure what you are meaning with that comment.27% increase in price, 36% increase in power at 4ohms. Hardly a monoblock premium here.
Power specs in this case are not the end all and be all but the Fosi certainly does look attractive. The NCX500 has benefits that are about low Z, high current and high temp drive capability for longer duration time periods etc. We will see after these babies are torture tested how they stand up. Otherwise I think the Fosi V3 is a amazing piece.Ncx500 as mentioned is 45% increase in price and no increase in power.
Could you, please, elaborate on this?The PFFB technology used by Fosi has been around for a long time. However, due to patents, this technology could only be used by certain manufacturers. Therefore, even TI, which developed the TPA3255 chip, was not allowed to provide technology using PFFB.
However, that patent expired about three years ago(?), and anyone can now use PFFB.

There will be increased crosstalk and low Z drive will suffer from channel to channel as peak current requirements occur.stack them using the single 48v PSU. No difference from a 2xTPA3255 with a single PSU
It a sweet looking amp for sure. I agree the NCX500 is altogether different amp and comparing it was a far reach.Fosi v3 mono indeed look attractive, Fosi have done amazing job with case work.
Comparing it with NCX500 isn't fare at all, but it does hold its own value strongly.
Is it because of their size they are desktop models??The products we talk about are often desktop models.
This is a power amplifier which means they usually don't have volume controls. You need a preamp in front of it or a DAC with volume control.
Fosi monoblocks - $280
Aiyima stereo - $220
27% increase in price, 36% increase in power at 4ohms. Hardly a monoblock premium here. The reviews also show monoblocks doing better at difficult loads.
Ncx500 as mentioned is 45% increase in price and no increase in power.
I already explained the very basic differences that are large when the NCX500 amp is in actual operation. Do you understand what the NCX500 and other class D Hypex and Purifi amps are about?I'm comparing the decision to go for monoblocks: with Ncx500 you pay 45% more and get no power increase while with TPA3255 you actually get more watts per dollar.

Unless your office is very small, IMHO you can get better results placing your speakers on stands and equalizing for your chair as a listening position. I tried both setups.
My prediction is also around -120dB (measurement limit value), but I wanted to check it at least once just to be sure. I think it's my chronic illness.With mono block amps using dedicated power supplies there will be zero crosstalk from the amps.
LoL.. I have a couple of those too... gg*I think it's my chronic illness.

Lucky dude!Thanks! Just filled out the early bird discount form!
Discounts are nice can mine be blue pleaseThank Amir so much for the measurement! The V3 Mono is another amplifier co-created with members, following the V3 stereo amp. We would particularly like to thank @Toku, @ModDIY , @mike70 , @cyclo, and all the other members who have provided us with invaluable suggestions.
The V3 Mono is our first amp with PFFB implementation. During the period we sent the set to Amir for testing, our R&D team did not stop optimizing the V3 Mono, and we have now further improved its frequency response curve. Below is the chart for your reference.

The V3 Mono is currently in production, and it will be launched on Kickstarter on the 20th of this month. There will be very attractive discounts available then, and we hope you'll stay tuned!
