Default Looking for a Full digital amp - anybody know of a nice kit?

Hi,

I am looking for a full digital amp kit or built PCB. I have come across quite a few threads on it on this site but non very definitive.

Has anybody come out with a kit yet, that doesn't require a PC to operate?

Alternatively a power DAC of sorts would be interesiting too if you know of one (cheap)....

Oooh nice... Any idea how it implements volume control? What exactly is I2S? I suppose I need a converter of sorts. Any idea how it sounds?

I2S at Wikipedia

You could rig up your own I2S transport, but if you don't know what I2S is, that's probably not advisable

You could use their miniDIGI board, which will accept optical and coaxial SPDIF as input. No volume control though.

You could use their whole platform, miniDSP + miniDIGI + miniAMP. Volume control within the DSP via 10k pot connected to a header. And you get a DSP as well.

There are a few reviews of the miniDSP setup around - I don't have it myself (still sitting on many fences)

Failing that, there's always the Panasonic home theatre receivers - fully digital signal path when using SPDIF or HDMI input. (Though I'm not sure if the latest models are)

Hi Fb,

Thanks for the prompt reply. I haven't had time to look at the reviews for the miniamp. What are the conclusion for it? Does it sound any good?

Hi authlxl,

Thanks for the info on the eval board. I haven't had a chance to look it up yet. Somhow I don't think they are so willing to give out their eval board so easily...

How did you like the sound for that one?
