Wadia 121 decoding computer

post #1 of 112
Thread Starter 

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.

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. biggrin.gif

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?

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

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. frown.gif

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.
