Look, i know where my problem is and you are partially right. But is not true that Fosi is not responsible for logistics... If you sell something to somebody and send it by mail, if the customer doesn´t receive the product, you are free from responsabilities ?I will surrender now, because I seem to be "wrong".
Good luck to the one who asked...
I agree, Fosi is ultimately responsible.Look, i know where my problem is and you are partially right. But is not true that Fosi is not responsible for logistics...

Fosi told me the monos are stuck in Spanish customs, and on the tracking it stop on Spain customs. Fosi ask me for evidences fromk kickstarter and credit card bill , and to send them . They told me to wait , and they assure the all duties. Last news was about 20 days ago...I agree, Fosi is ultimately responsible.
However, are you sure that the items are with Spanish customs? I would enquire there.
I would also enquire with the logistics company.
You have the tracking number and the name and address of the destination.
They are either still in transit with no evidence of final delivery or they are lost or stolen. Depending on where they are you may have to take what you’ve found out back to Fosi. Good luck with it.
I am not familiar with the kickstarter procedure and its obligations for the seller, thus I will keep my mouth shut nowLook, i know where my problem is and you are partially right.

I asked Fosi how to distinguish units with/out reversed phase and they sent this. Note extra QC label for units without inverted phase. My units from Amazon received Aug 20 were inverted phase.By any chance, have you checked if the Amazon units currently shipping in the US are "phase corrected" or "original" ? Just curious.
My fault. I didn't read ist correctly. I removed my posting already...Well, isn’t that what they are stating? 2 stickers = not inverted phase?
Link please?Archimago has part one of his review up. FYI
Even WITH the DC filter in place, when using single-ended/RCA inputs, he still gets the noise with a single power supply feeding both amps. With balanced/XLR inputs, no noise. Probably the best path to take when implementing these amps is either don't share power supplies or only do so if using balanced inputs, and not when using single-end inputs.Part I: Fosi Audio V3 Mono Amp; Class D + PFFB, TI TPA3255 - Retail box with single 48V/10A power supply and filter.

It's Okay when both are on, I am pretty sure in his article. Also in my experience. I quite like my dinky little filter even though they were both fine without itEven WITH the DC filter in place, when using single-ended/RCA inputs, he still gets the noise with a single power supply feeding both amps.

I also have that noise. Fosi answered that without this filter, the noise would be louder.Even WITH the DC filter in place, when using single-ended/RCA inputs, he still gets the noise with a single power supply feeding both amps.

One of the reasons, why I chose a separate 48VDC/5A power supply for each of those amps.I also have that noise. Fosi answered that without this filter, the noise would be louder.
From the archimago.blogspot:
"With the rated 240W into 4Ω 1%, we're looking at maximal we're looking at maximal 31Vrms so if using the +25dB gain setting, the source should be able to provide up to 1.75Vrms. With the +31dB gain setting, at least up to 0.9Vrms. ... Most modern source devices (DAC, preamp, streamers...) should have no problem providing at least 1.75Vrms output"
Sorry if this is a stupid question, but why "at least"?
If in my Wiim Ultra I can set: 500 mVrms, 800 mVrms, 1 Vrms, 2 Vrms output voltage manually - are any of these settings beneficial for sound quality, or completely forbidden? On the Wiim forum it's recommended to set such output voltage to conveniently control the volume. Can any of these settings can negatively affect the sound or the v3 mono units itself?
