there is def a difference between the 2 machines.
i've owned 4 MPC 2000XL's in my lifetime so far. it's like my first girlfriend and first mpc i really learned how to use. it always seems to come back to me or i go back to it.
i've owned 2 MPC 2500's in my lifetime so far. Had a black one and now have an MPC 2500SE.
i can speak from experience. this is what i've found.
there is def a difference in the swing, sound, feel of the pads and features of the 2.
i found that the MPC 2000XL def has a better swing and feel over the 2500. you can notice it when you use the note repeat on sounds and also just in laying basic drums with the standard quantize settings on both machines (1/8, 1/16, 1/32, etc...) the 2000XL seems to be a bit looser and have a better hop to it, especially in the kicks and note repeat for hi-hats and snare rolls, etc... the 2000XL also has a warmer sound, better low end and sounds really good with string and guitar samples. the 2500 is not as loose, doesn't have as warm, full and round of a sound in the low end and is a bit more mid-rangy on samples.
with that said, i love the mute groups, usb, internal hard drive, direct record feature and some other new features of the 2500. the effects aren't bad if used right, the filters are not bad (although the 2000XL only has a low pass filter, i think its a bit warmer than the filters on the 2500. especially for bass sounds). you can play with the swing setting on the 2500 and with some work get good results. also doing some things quantized and some things not on the 2500 helps a lot. also when you track your beats out of the 2500 and into Pro Tools or whatever DAW you use, you can eq compress and mix things to make them sound fuller, warmer, wider, etc...
i love them both. right now i'm sticking with the 2500SE and i also have and MPC 60 MKI, so i can can some 12-bit punch and warmth, plus that classic Roger Linn swing out of the 60.
i would like to get another MPC 2000XL at some point. i really love that machine and it has done me well over the years. i've made some bangers with it.
to heard the difference on some of the things i'm talking about check out these heads and listen to the difference in the sound quality of their beats.
MPC 2000XL
Bangladesh
Marco Polo
KutMasta Kurt
Jaisu
Panik of The Molemen
Stu Bangas
J Scrilla
Newer Pete Rock beats (he use to use the SP-1200)
Older Heatmakerz beats (now they use the MPC 2000XL & the MPC 4000)
Some of 3-6 mafia beats (they use the MPC 2000XL and the SP-1200 sometimes)
Some of Mannie Fresh beats (he uses the MPC 2000Xl and the SP-1200)
Disko Dave
Some of Kanye West beats (sometimes he uses the old MPC 2000)
and there are still plenty of producers using the 2000XL that i'm forgetting
MPC 2500
Araabmuzik
Newer Alchemist beats (he use to use the ASR-10. ive seen it in his studio, so he still has it)
Older Sid Roams beats (especially on Product of the 80's and some of the stuff they did for Hard White)
Ty Fyffe
Frank Dukes
New Showbiz beats (he use to use the SP-1200)
New 9th Wonder beats (he use to use FL Studio)

Jim Jonsin
Chad-lo
Emile Haynie (produced a lot of stuff for kid cudi and use to work with Disco D) here's a great read about his workflow on the 2500 and video of him in the studio
http://emusician.com/interviews/feature ... hop_emile/http://www.youtube.com/watch?v=sXI9JlFjTQUgo on youtube and search all these producers. you can hear the difference in sound quality between the machines.
there is a difference in sound quality, swing, feel, features, build quality, etc... between all the MPC's. i love them all.
i think the MPC 4000 is prob the best well rounded MPC for clean or dirty sounds, with a nice swing feel and some great features, but it's a little too complex with all the windows. The MPC 60 and 3000 are classics, sound great feel great, the 2000XL i think is very well rounded and versatile. you can get some raw boom bap out of it like marco polo or some radio ish like Bangladesh. the newer MPC's 2500, 1000, 5000, 500, def have their pluses and minuses.
at the end of the day all that matters is being comfortable and happy with the workflow, sound and feel of the machine you have and getting work done.
it is nice to have more than one MPC if you can. It's also nice to have some ensoniq samplers (EPS, EPS 16+, ASR-10) and an SP-1200 and an Akai S950 and a Boss SP-303, and a... ok let me stop there.
