wadia i170 meassured jitter level

USArmy, I don't think anyone is questioning your results, but there are many variables here, probably even far more than I know. Maybe your DAC doesn't reclock, maybe it does, maybe this, maybe that...

You say, "Even if your dac does a good job of lowering the jitter its still better if its done in the transport.". I disagree. While the obvious thing is that no jitter anywhere is best, but lowering jitter at the DAC is better. If jitter is dealt with at the transport level, jitter can be introduced again down the line vs. addressing it at the DAC just before it gets converted to analog.

What ever the case is the wadia i170 or the ipod it still has a very high measured jitter from the digital output

This may not be a reflection purely on Wadia...it seems that ALL digital interfaces suffer from it to some greater or lesser degree. This is WHY it is so important to use a DAC which has some effort made at reducing jitter other than the old and to basic PLL method (various schemes exist form buffering to asynchronous upsampling etc. etc, - pick your posion)

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 recommend reading Martin Colloms review in HiFi Critic. In a 4 page long review, he compared the Wadia iTransport to several, "regular" transports and CD players, and was SERIOUSY disapointed by the results he got.

Elberoth, I am all for reading it, if I could get my hands on it. BUT, I have already done this myself so I have personal experience; I also have read numerous comments from others that mirror mine, published and on forums. If others are disapointed, so be it, I have been happily listening this afternoon!

Brianmgrarcom why do think company's like dcs and esoteric deal with the jitter befor the dac? They have outboard clocks to deal with jitter before the dac does? So just because you dac does a good job of reducing the jitter it cant be better than outboard clock. Empirical audio makes a outboard clock called the pace car 2. I think this could make the wadia a better transport.
