My understanding is that the 48v/10A is mainly to allow the amp to be 2ohm stable. It shouldn't have any impact on the sonic qualities of the amp, which is why you wouldn't notice a change in the sound.

I know, I know, I was trying to be sarcastic

Not so pleasant for you, but maybe for those who couldn't decide on buying yet: It's not only the 48V 10A power supplies that had a huge price cut.
There's a summer sale for all 3e Audio models from A5se to A7 Mono on AliExpress now.
I don't think it's a price cut, I think it's just been put on sale for a period of time. FWiW, the A7 is now on sale for $297 CAD, and I paid $390 CAD...

My god... my eyes didn't move past the first line, I'm sorry
Yes, for sure. Depending on when they ordered the power supply, maybe they could contact 3e, and see if they'd be willing to offer some kind of rebate/refund for the difference.

I can. And I did, less than one hour ago, at least.
All A5/A7 and the A5se and A7se.
So strange... It's the same in the app (where I'm logged in) and on the website.
Edit: it works when adding "amplifier" to my search

Will you be expanding Amazon coverage to other countries?
In my case the Fosi V3 monos were a total disaster so I ordered the 3e audio A7 stereo version. I should receive it tomorrow. I was wondering about power supply upgrade but I guess the included 48 volt 5 amp power supply is completely enough. Thanks.
And we are very grateful for this opportunity.
I think they have said that the 5A power supply is good for speakers 6-8ohm, and the 10A is good for basically 2-8ohm.
I think in this case I should be just fine. My speakers are rated for 8 ohm. Thank you.
For first time ever changing L and R, 2 opamp do nothing, have you tried changing the opamp at rca to xlr, mine is like superglue.

Hello everyone!
Just registered to ask respected experts here for advice - on which of below devices should I preferably adjust the volume in my setup, considering minimal signal loss and the best sound quality? (auto-off function on A7 will be disabled as it is the new revision)
Wiim pro --> coax -->
Fosi ZD3 dac --> xlr -->
3E A7 -->
Onkio D302-E speakers (4 ohms, 83 dB/W/m)
In view of above discussions in this tread I am tend to use Wiim for volume control, fixing it both on dac and amplifier. Many thanks for your opinion!
