Personal opinion to follow:
I just got myself a 1010 from a fellow homerecording.com member. It hasn't shipped yet, but I did quite a bit of studying in regards to which unit I should get. I have a Delta 1010LT right now: it delivers much of the same universal connectivity, high fidelity and seamless performance as the popular Delta 1010 on a single PCI card—and at a fraction of the price. Multiple analog I/O, MIDI, S/PDIF and surround sound support are all there.
Two inputs even have mic/line preamps on XLR connectors, saving the expense of outboard preamps. It’s all on a compact, half-size PCI card with two color-coded breakout cables. Combine up to four Deltas in your system for a maximum of 32 analog and four stereo S/PDIF inputs and outputs.
I would not recommend the 1010LT if you dont want to have a mess of wires hanging off the back of your computer tower. Also, unless you have a patch bay/outboard mixer, you are going to be unplugging and plugging in from the back of the comp, which gets annoying fast.
1010: As a samplist, the delta 1010 is a great choice as it works at any sample rate, including the odd rates like 36khz, 29 khz and 39.11 khz or whatever. You can take it up to 24bit 96khz if you want.
The outputs can take balanced or unbalanced cables, impedance can be set to -10 or +4 depending on your mixer. Running +4 balanced allows you to interface with professional mixing boards with minimal noise.
You get 8 analog ins and 8 analog outs, stereo s/pdif in and out, so that 10 in and 10 out al together (hence the name is "1010") and all the ins and outs can be used simultaneously. This allows enormous flexibility. Go mixerless if you want and connect synths and preamps directly to the 1010. Or connect to a large 8 bus board. Or configure it so out 1-2 is the master out and use the other 6 outs as busses to hardware signal processors.
The Delta 1010 has a midi port which is reliable and can be used for heavy synth work.
The one con if you didn't know this The Delta 1010 does not have mic preamps. But if you are looking at the 1010 you probably have the mic pres taken care of already.
