DAC-END 24 (AD1865 NOS DAC )

DAC-END 24 (AD1865 NOS DAC )

AD1865 is a dac chips with natural sound and inspiring.

ago, Andrea and I had success with DAC-end, now I have upgraded dac-end 16-bit, 24-bit up-end DAC.

it receives the input frequency of 192 KhZ- 24bit and special use Amanero to use USB audio source from your computer.

Looks good Quanghao. Any details on the IV boards? Are these the LL1660 version?

Do I understand rightly that your DAC board does not include the AD1865NK Chip? Ebay is full of fakes! Do you know where to get the real thing from? Also, does the Dac-End24 board include the Transformer?

All the best for 2015!

Thank,s Rol,

you´ve bought the kit?

The IV PCB look´s interesting, Quanghao seperated the tubes sockets from the PCB? For what he made this?

I´ve still here a kit of the first End-DAC, the IV circuit might by the same?

Just have the IV PCB for lundahl 1660 with ECC182 stage?

The "old" DAC-end have 6 voltage rail, it wan´t better or was simples to much?

The price of the assabled DAC the Amanero USB is just incluided?

Yes, I just received the kit today.

This time the tubes are mounted horizontally so they need separate boards.

The IV is almost the same, just with some tweaks for tube choices and room for bigger film caps.

AFAIK, the new Lundahl IV is in the work.

The PSU seems to be simpler than last revisions. Still very good, way more than enough to provide clean power for the DAC.

Yes, for $300 there are the Amanero and transformer for DAC section. No stock for the Amanero right now though.

Hi Quang Hao.
I'd like to buy assambled and checked:
1) DAC (AD1865) with Amanero-USB module but without transformer
2) R2R shunt volume without standby configuration and without RCA sockets. Black remote control and red LCD display will be welcome.

I'll do appreciate for quick replay, Marek.
