Hi, I've run into similar issues with the M-Audio Delta cards - a need to put isolation transformers in the audio lines to get a clean sound.
I've also run into an issue on the Delta 1010 about a year or two ago where I had to replace bad capacitors in the breakout box (bulging caps). It isn't difficult to change, however it was an annoyance. I'm not sure if this is a common issue with the 1010 breakout boxes or if it was just this particular box had the caps go. But on the other hand if you're looking for an inexpensive card (especially if you're willing to purchase off ebay) that can do multiple inputs / outputs, has decent Linux support, and you're willing to live with the fact that you might end up putting in transformers in the audio lines (or replace a cap or two), the m-audio delta line isn't all that bad. > > NOTE: Those M-Audio Delta cards use breakout boxes for the I/O and the so > called balanced inputs are not truely balanced.
