From the 20dB gain, and calculating the volts you need for 120W output at 8ohm. (120W being the power you get at 1%THD)Where did you get the input sensitivity value from?

Ok, I see, you're considering 20dB instead of the max. 31db gain value (RCA input) because the input source is around 10-12dB less, I'm right?From the 20dB gain, and calculating the volts you need for 120W output at 8ohm. (120W being the power you get at 1%THD)
Either you've misunderstood what someone told you, or they were teasing you, or they didn't know what they were talking about. The flash storage in SSDs doesn't need power to keep data for months, often years. It's similar to that in a USB drive or microSD card. The bit that needs power to retain data is RAM, but it's extremely unlikely any of your files are stored there, other than as a temporary copy.I would. Once I've made a digital copy of my LPs and CDs on a small PC using SSD storage it is essential to keep it on charge, otherwise you can lose electrons and the music is lost - 5 watts is nothing to leave on 24/7.
Because the person I was replying to was using XLR. Which is 20dBOk, I see, you're considering 20dB instead of the max. 31db gain value (RCA input) because the input source is around 10-12dB less, I'm right?

I was trying to figure out why I have the same "problem" as others with Fosi and my DAC (miniDSP Flex HT) which delivers up to 2 Vrms using RCA.Because the person I was replying to was using XLR. Which is 20dB
On the RCA input/31dB (x35.5) gain, then you have an input sensitivity of 0.87V (8 ohm for 120W)
On the 25dB setting (x18) then input sensitivity is 1.7V
Even if that were true (it is not), what does leaving your amplifier on 24/7 have to do with the SSD in your computer? (Answer: Nothing at all.)
Edit: BTW, You may be recalling from a really long time ago. In the very early days of solid state storage, this was true.
You would make a big favor to the friends here if you opened it and take some pictures up close at both sides.
Did you try swapping PSU?Nothing looks out of the ordinary.

Yes.Did you try swapping PSU?
(if you use the 2 5A ones)
It could be that too.
Because Marantz has ten times lower input sensitivity compared to Fosi.With my old Marantz SR6009 (110W/8 Ohm) I have no problems driving my B&W 685 S2 (87dB/8 Ohm)
Once again, please try to read and understand the comments of those who help you, there is no lack of power.I was trying to figure out why I have the same "problem" as others with Fosi and my DAC (miniDSP Flex HT) which delivers up to 2 Vrms using RCA.
With my old Marantz SR6009 (110W/8 Ohm) I have no problems driving my B&W 685 S2 (87dB/8 Ohm), but with the miniDSP and the Fosi the lack of power is clearly noticeable.
Uhmm, but this only applies when I use the Marantz solely as an amplifier (which I tried connecting the miniDSP to its 7.1 CH IN inputs), but when I used only the AV receiver?
Sorry for bothering! I'm struggling trying to understand why I haven't gotten the results I was looking for.Once again, please try to read and understand the comments of those who help you, there is no lack of power.
I Can make you an offer of 230$ for the 2 V3 Mono with 48V 5A PSUsAre you trying to replace a Sansui AU-9500 with the Fosi's? How much do you want for it?
But if the Fosi V3 Mono Can reach 2x120W with 5V inside, why shoule I put 100V inside ?I like the schiit kara with 12db extra gain in xlr mode
In the previous pages you will find excellent explanations of @antcollinet , you cannot expect him to explain everything again every time a new user makes this observation.Sorry for bothering! I'm struggling trying to understand why I haven't gotten the results I was looking for.
This is a good thing and good advice and I hope so...Turn that volume knob, the trend of listening volume at 9 o'clock is over

Your Maranz only needs 0.2V input for full power.Uhmm, but this only applies when I use the Marantz solely as an amplifier (which I tried connecting the miniDSP to its 7.1 CH IN inputs), but when I used only the AV receiver?
Do you mean I need a more powerful amplifier because of the higher input sensitivity?
