The should both be just fine but the 1010 has well 10 inputs/outputs, the 2496 only has maybe 2 or 4? I used Delta 66s for many years and they were some of the best interfaces I'd ever used. My only drawback these days is aren't they are owned by Avid now? I doubt the support is what it was before M-Audio was purchased but could be wrong. I'd check to see if they are still supporting the latest OS's driver wise, that's' really the concern I'd have.
2cents My first card in 2002 was a 2496. Not once did I experience issues with it. Back in the day M-Audio's drivers were known for performance. Very recently I dug this old card out and put into my retired DAW PC with a gigabyte UD3 motherboard. Fired right up and went to work right away, and reported very similar latencies to the RME Hammerfall that it replaced in the PCI slot, ie low enough for guitar sims ( subjectively ). It's good hardware, and the driver I installed for it showed no quirks.
My first audio card was a 1010LT, which I used with a small mixer. It worked and sounded good, but the two builtin mic preamps weren't usable for anything. The unbalanced inputs/outputs were not an issue. I have no experience with the 24/96, so I couldn't say how they compare.
Delta 1010LT great card for its price with pros and cons. We use it at our first studio. There was no issues all the time with it. We just assemble the system and forgot about card (only change buffer size - small for recording, big for mixing). Con: Unbalnced inputs (RCA) - eg you'll get noises if your cables are longer than ~5 meters Pro: Don't use long cables (our was about ~2 meters and we had no troubles with noise) Con: Only 2 amps Pro: You get only what you've payed. You don't overpay for preamps and get only 8 line-level channels and can use any preamp you like. For instance we'he used 8-channel mixer with inserts (which can be used as direct output with right cable) for multitracking drums, and separate preamp for mic. PS yes, there are two mic amps, but we don't use then (can't remember why). Imho it's quite good device for this price. > I like to use mostly headphones and mic with these. Are you sure that you need 10/10 for this? If you don't need record 8 channels at one time, may be there is a reason to look at Delta 4/4 - similar device with BALANCED 4ins/4outs. Update: At any case as for 10/10 as for 4/4 you'll need a separate phones preamp - any small mixer or separate phones amp
I used to own a 2496 - audio quality was very good, and latency was very low (a benefit of living on the PCI bus) You can get 4 simultaneous inputs with that card using an SPDIF to phono converter; It will force you to 48kHz sample rate however. Drivers used to be ok on XP, but I can't comment on later versions as I moved to Focusrite gear around the same time as I did to Win7. Just remembered - the software that came with it for internal mixing on the card was highly confusing... but you only need to set it once :) It also supported recording 'stereo mix', which was handy.
Pet: "You can still download the latest driver that officially supports Win7 (64bit) SP1. The driver for the 1010 is the same as mine, works here with Win10Pro64 anniversary update without any issues. But I made an upgrade from Win7Ultimate64 and read somewhere that if you make a fresh W10 anniversary install there can problems occur, cause that old driver is not digitally signed. But there are already solutions for that, afaik." Is this also true for the Delta 1010LT? If yes, can you provide a link to the correct driver to use for Win10? What is the way to get around the unsigned problem? I would like to bring this card back to life.
@panic: What if you turn it on, install the driver and than turn it off again? @merdave: I came here again to post a link that coincidentally describes in detail, what panic says. Here: Peter
