DAC-END R (ES9018) full assembled board - version 2

[blackberry]

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 +output stage
6. MattMax: output stage
7. CAAD: output stage

8. Blueberry: output stage

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.

Hi quanghao add me to the list of your new output stage. name is blueberry.

I think you are supposed to copy and paste the latest list adding your details as instructed here.

And thank all!

Hi quanghao can i buy only a frontplate and a remote from you, and what is the price sent to Denmark.

I think mr "blackberry/blueberry" removed the entry "Mas Penk" made? Anyhow whats the projected timetable on production/delivery after the groupbuy closes?

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

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.

 

[quanghao]

a few weeks now, I'm busy with the ES9018 DAC V2 test, invite you to view photos!

Thank you!

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 😀

I just hope the shipping is still acceptable... 😉
