Battery Based High-End DA Converter.

[yangsmm]

I designed Battery Based High-End DA Converter.
It operates only on battery for about 6 hours. When user switch off, then it automatically starts to charge. It also have over charging provent circuits. It support Optical and Coaxial digital audio input and DACT Volume(100Kohm) is used for attenuator.
I'd like to listen to other peoples' opinion.

It looks very nice. Are you willing to share your schematics or maybe some performance measurements so we can see how good it sounds?

 

[yangsmm]

I can share the performance.

I have audio precision, so I'll measure it and share the datas.
For Sound, I tried OPA627 and AD827, Then can you guess how it sound ?

[yangsmm]

GBP Calculation is...

How much GBP would be charge for shipping to UK?

When I converted Won to GBP, That would be 413.688[GBP], not including shipping fee. But Including shipping fee, then I think it require 55[GBP].
