I've had a Delta 1010 since 2001. Done 2 albums on it for my band, and a few demo recordings for other bands.
At some point, not sure when, something went wrong inside the breakout box. If the rate is set at 96khz, there is a huge white noise from every second input channel (2,4,6,8). No noise at all at any other setting. So, I just keep it set to 44.1 with no problems.
Other than that, since ironing out driver issues back in the stone age on a 400mhz celeron, it has worked perfectly.
If you want to hear some of the recordings done on my delta 1010, check these out:

All preamps were from a 80's Allen and Heath System 8 mixer.
Good luck!
