What do you mean by upgrade or original? As I said, the two version of power amp modules are one for full size headphone while the other for smaller headphone / IEM / earbud. There should be sticker on the back side of the amp module telling you which is which. There is no 'upgrade' or 'original' power amp module.

This is the new version they talking about, clearly different board then mine, and both ST version and both can drive iem and full size can.

I'm not talking about the game card that specialize for IEM, and definitely not the balance card.

The pcb on what they cal ver2.0 is green, and as you can saw, mine is blue with very difference layout, so clearly there are several version of the ST amp of 801.

You are thinking of the whole things with the wrong order in time. The picture you are quoting is back from 2010, and that isn't the new version, but the OLD version. Power amp card is actually newer than any of the STD card.

HM801 originally came with 1st STD card with OP275 back in 2009. Then in 2010, the 2nd STD card with OPA2107 was introduced (it looks the same as 1st STD card, the same one in your picture above), which is when this thread was started. Both of 1st and 2nd STD cards were marked as 'V2' card - it is an internal reference for HifiMan and has nothing to do with how new / old the card is.

In 2011, power amp module (the blue card you have) and 2nd STD card were both included with HM801. Later, the package became two power amp cards with different gain.

To sum it up, the order goes like this in time: 1st STD card -> 2nd STD card -> Power Amp + 2nd STD card -> two Power Amp cards.

In short, there is no upgrade for your Power Amp card as it is the current card.

oh IC IC, thx for the explanations ClieOs, I bought my HM-801 second hand, so I only got 1 card, and it broke, so I need a replacement.

Thanks again.

Firmware update from 0.20 to 0.21

In the process, I must copy the new firmware to the internal flash memory, but I can't format or access the internal memory , the HM-801 and computer

already connected .
