Peachtree DAC iT vs. Benchmark's DAC1


I have read that Peachtree Audio's new DAC*iT re-clocks jitter to 3 picoseconds "when measured at the master clock," whatever that means.
Atkinson's DAC1 review in stereophile states a jitter rate of 157 picoseconds for 16-bit audio signals.

First question: considering that a picosecond is one-trillionth of a second, can we even hear the 154 picoseconds difference?
Second question: is there any truth to Peachtree's claims, they have a DAC that smokes the Benchmark in jitter reduction for half the price? Or is this just a trick of how the jitter is measured?

I too have owned the Nova and the Benchmark. I greatly preferred the Nova (though only it's DAC section, the amplifier is not very good at all). I completely agree with the build quality comment, the Nova was very cheaply built, where as the Benchmark was particularly well built considering it's price point. To my ears, the Nova pulled the same level of detail as the Benchmark, but did it in a far more musical way.

I have also owned the Eastern Electric Minimax DAC, I prefer this DAC to everything else I have heard, though I had reliability problems with 2 units and ended up returning them both.

My DACiT should be here by the end of the week, I am curious to see how it can compare to the Eastern Electric's sound, given that it uses the cheaper, less sophisticated Sabre 9022 instead of the Sabre 9018. Should be interesting.
