wadia i170 meassured jitter level

I think the facts are that the 170i has high jitter as this has been objectively measured. The extent to which this is audible, in my experience, depends on the DAC and its jitter reduction processes. My experience is the same as Brian's - I could not pick the difference between transports when using a common DAC, but only after a DIP jitter reduction device was added to both devices. Without the DIP, using the same non-reclocking DAC, the CD player had better resolution. So Brian, if your DAC does reclock the signal and reduce jitter, this may be the key reason you didn't hear a difference.

Having said that, I agree that Wadia could come out with a higher-end version - perhaps with improved power supply, improved clock and a better digital RCA plug (with a sturdy digital cable, the rca plug on the Wadia moves about disconcertingly).

Hens, my DAC does reclock the signal, a must in my buying decision.

Where are these measurements? I am not saying the statement isn't true, I just have never read anything published. Your DIP experiment does raise legit questions.

Talking with one reveiwer in the past he mentioned comparing a couple transports, one expensive, one not, while using a DAC that reclocks and could tell no difference.

I talked with Martin Cooper of Wadia early last year, before the i170 was released, and they did have ideas for a separate power supply and the like.

As for those considering an i170, I would just be sure you paired it with a DAC that reclocks the signal.

The i170 has 0 (no jitter). The jitter is from the ipod that is connected to the i170. I wonder if solid state drives have a jitter component.

I located where I had read this and it was from Gordon Rankin on Audio Asylum who measured the jitter. Atkinson also stated in the Stereophile review that the jitter was high but didn't specify a figure.

The sound I now get also matches my "reference" sound and that's more than I expected!
