I've google some info about Wadia's DAC, and found this. http://www.wadia.com/products/decoding/121/
 
I found two different panel of 121, @wadia's site should be latest version.
 

 
Wadia's newest digital statement

Cool stuff!
 
Most I wanted is a compact high performance DAC w/high quality headphone output, and the price @entry hi-end.
 
Hope Wadia 121'll coming faster.

Wadia offically put 121 on their site.

Preordered I'm disappointed that the specs page does not say which chip this uses. I hope it is the 1704.

Available at Music Direct...I wonder how they sound powering the Orthos.
Very curious? 
 
Anyone tried these yet?

 

[some1x]

That was pretty disappointing. Huge amount of noise in headphone output using USB input. Returning...

Thank you!

From what I can tell from their website, it's their own proprietary DA conversion software?

Some answers from Drew at Moon-Audio can be found in this thread, in particular on the chipsets used and there's a manual as well.

Do you think it was a defective unit or just a poor result from Wadia/RSA?
 
I so wanted this to be a great product, holding out hope.

Deleted, mistake.

Only way to tell is if others also try it. I only tried using USB and using headphone out (this was my intended use case, so I didn't bother trying other combinations). The noise was definitely digital in nature.

I'm keeping my hands off then, I had the same problem with another amp/dac recently. Had to send it back for a refund. None of my other Dacs I have/had ever had that problem.

Any more head-fier tried Wadia 121?
 
I saw some positive feedback @another forum, they've compare 121 with W4S DAC2 and 121 is better.

I have the Wadia 121 DAC breaking in at home now and will let you know what I think of it in the near future. I will say that first initial hearing is mixed as I heard a a wide, but not very deep sound stage. Dynamics were also some what on the short side.

Congrats!
