i kinda have to agree with middleman here......i like my 2496 card plenty--it's a great $100 card, even considering i paid $150 for it 3 years ago. however there is a substantial difference in the sound of it and the full-blown delta 1010 (i'm not talking the LT, but the rack-mount version). on the 1010, the converters just plain sound better to my ears.....the noisefloor's ~15dB less (granted, we're talking a low starting point in the first place), the inputs are on balanced TRS rather than on rcas, and the conversion happens outside the computer rather than inside. all of those things add up. still, i've made plenty of decent recordings with my 2496, and it's still in my machine b/c the extra 2 inputs is nice to have around "just in case".
still, i have to agree with Dot more......i'm certain that even with the 2496 card, if you were to get the DMP3 and a pair of 603's, you'd get a *substantial* improvement in sound over top of the 3035 and the mackie. i'd vote those two not as your weakest links, but as the first things you should address--*then* get the 1010. i just think that if you want immediate tangible improvements, you might find the 1010 coming up a little "short" when you're still fronting it with the mackie and 3035......the difference the 1010 makes will be more "subtle" compared to the difference in a pair of 603's/DMP3 vs Mackie/3035.
something to consider, though.....having heard and played a number of HD35's, it might be a little "ballsy" for the 603's. the 603's have a bit of a bump in the high end, and that might make them a little "too much" on that particular guitar. i have a D15 (all solid mahogany with a nice, mellow sound) and they're just what the doctor ordered. they're *not* all that great on my buddy's HD28. you might be best served getting a pair of the 603's *and* the oktava mc012's (along with the aforementioned DMP3) and keeping whichever set sounds better on your guitar in your room, as the mc012's tend to be a little darker in contrast to the 603's. float the credit card $150 for a few weeks and make an educated decision at home. can't tell you about the guild, but given the spruce/mahog, i'd wager it's a little more "mellow" than the hand-cannon known as the HD35

(and thus maybe a better mate for the 603's--you might find yourself getting/keeping both sets of mics b/c not every mic responds well to the every source).

PS--while i agree that it's generally bad to upgrade for the sake of upgrading, the sound of my guitar recordings went "through the roof" better (comparitively speaking) when i switched from my mono SP B1/VTB1 combo to a stereo pair of 603's paired with my Mackie24*4. sure, the B1 did a "perfectly fine" job recording it and i love
my VTB1......but the pair of 603's (and positioning flexibility afforded therein) do the job so much *better* (even with the mackie as pres), so i'll be glad to make the recommendation to "upgrade* here. and besides, when's it bad to add more weapons to ones' arsenal--can't go wrong with a DMP3 and 603's? here's to hoping for an RNP for christmas.
