Merci amigo )

First feedback amigos :
Wondom IRS2092 is OK, sounds pretty well very powerfull but a bit noisy...
But we are very far away from the Combo AIYIMA TPA3251 + Burson Audio AOP, for the moment I did not find something better.

Thanks I know. But this is one I have at home...
So just want to know if my connection diagram is correct in the picture ?
Many thanks )

1.Try different amplifier with the same signal source.
2. Disconnect inputs. Any hiss?
3.short inputs. Any hiss, any change in hiss?
4. Report back.

I made a test with the folowing : Source = LG V30 + HD Audio music
Preamp : DAC AK4497 > to Amplifier via hight quality RCA cables
Source : Bluetooth APTX HD , LG V30 to DAC AK4497
0) disconnected input = seems OK
1) TPA3251 + DAC AK4497 = dead silence
2) IRS2092 + DAC AK4497 = noisy (kind of hiss)
3) I shortened the Inputs into the DIY Amplifier = the same (hiss)
4) Tested with another pair of RCA Cables + DIY amplifier = the same (hiss)
5) Bypass the AK4497 DAC and fully connected LG V30 to Amplifier via RCA cables = the same (hiss)
It seems that IRS2092 does not like my source = LG V30 audiophile phone.
Anyone have experience with a Sure AA-AB32291V110 ? Any chance it will run on a 59V +/- linear PS? How about real wattage, or to be more frank things rated at 1%thd or worse 10%thd are unusable to me, I cannot find an output of this board at .1%...in general is this a board anyone would use? Thanks
