1010's advantages:
has a breakout box
has 1/4" balanced inputs/outputs
1010lt has RCA unbalanced, no breakout box
1010lt's advantage:
has 2 nice preamps based on DMP2 technology
$150-$200 cheaper
i still havent confirmed with Delta which converters the 1010 lt uses.....the 1010 uses AKM AK5383 converters for A/D and AK4393 converters for D/A.......
if you are gonna keep your inputs all hooked up to a mixer/preamps, lack of a breakout box is not that big of a deal....if cable runs are kept short, unbalanced isnt that big of a deal.....converters on the pci card isnt that big of a deal considering some very quiet cards have converters on the pci card (Aaardvark DP2496 being one)......
