Here the PCB layout of the new output stage (We say : DCS V/Istage ), the main specifications:

- no feedback
- very low distortion because it work as current amplifier
- Vbe nonlinearity compensated using diamond buffer on output stage
- zero dc offset using dc servo loop
- variable voltage gain only changing a single resistor (I/V)
- high output current to drive any low impedance headphone in pure class A
- high output voltage to drive any high impedance headphone
- very low output impedance to drive any cable
- both un-balanced and balanced output
- differential configuration to reduce common mode DAC errors
Hi quanghao add me to the list of your new output stage. name is blueberry.

I think mr "blackberry/blueberry" removed the entry "Mas Penk" made?
Yes, somewhat impolite to delete someone else's order.
Corrected GB list:

1. adeveza: DAC module + amanero + output stage + transformer (Complete Set: Item 6)
2. papapew: DAC module + amanero + output stage + transformer
3. smokingdog: DAC module + output stage
4. gde3: DAC module + amanero
5. villanueva: DAC module + amanero + output stage + transformer (item6)
6. MattMax: output stage only
7. CAAD: output stage only
8. blackberry: output stage only
9. Mas Penk: DAC module + amanero + output stage + transformer (item 6)
10. rade95: output stage + chassis
 
a few weeks now, I'm busy with the ES9018 DAC V2 test, invite you to view photos!

Thank you!

And I see that 3 people have listed "item6", although there's no mention of the chassis in their order.
It's worth noting that Item 6 actually includes the chassis, and full assembly.

It's hard to looking for a good chassis in my country... That's why I think it's worth to include chassis .. too many project of mine are naked :D

I just hope the shipping is still acceptable... ;)
