Hi John

Good to see some new graphs in your plots showing the measurement of the behavior of the digital reconstruction filter with a technique, we discussed in January at the CES. With that, you and your readers can see more clearly, what is going on in the digital filter, at least in the frequency domain.

I ordered and received an iDac and have loved the sound, but I experienced a problem with the mini-jack. It doesn't hold the plug securely and that results in crackling sounds. I use it to feed sound to an audio system (not headphones) and with the volume control so close the jack, when I make volume adjustments the jack makes and loses connection - heard audibly in the sound system

I returned the first unit and after waiting months to get a replacment found that the replacement does the same thing. Seems to be a design flaw..

Anyone else experience this or have a solution?
