Hi,
Is it possible to achieve better quality with this DAC, than for example, highly priced hi-end cd player?
I understand that DAC can play up to 384khz resolution files, but is it really not suffering from jitter, computer usb output distortions and so on..?
Please advise, will it be good source for superior audio system?

Thanks in advance

I had to use a lt1963 for USB, you just plug the jumper for it!
thanks

Quanghao,

If it is not too late, I would like to order one DAC base, with I/V stage, Op amps, mains transformer (220v), and Amanero.
How much should I pay?
Can I pay directly to your account?
Thanks

I was just wondering if the company you got the chassis from does a similar sized chassis for a mini-itx computer motherboard.

Yes!
1. This DAC uses the ES9018, that's one of the best converters
2. all the power supplies are separated shunt power supplies
3. high quality components, very good crystek clock
4. Amanero USB interface
5. different I/V converters and output stages can be used to your preference: standard opamps, Audiodesign tube output, Broskie unbalancer.
6. Can play native DSD (SACD)
7. Nice orange PCBs

yes , i should order one, if Quanghao has left some..

does it make sence to use Sowter or Lundahl transformer in I/V stage, amplify with some tube(12au7) and output through hi quality capacitor (PIO or propylene)?
is output transformer better than output capacitor?

i don't like opamps...
