Two sets of white Alps sound/feel very different

The two keyboards are a Dell AT101 that I've swapped white Alps into. It also has fairly thick double-shot ABS keycaps from a Lite-on SK-2002. The other keyboard is a Focus FK-9000. It's all stock.
I've attached a sound file that has both keyboards typing. The first one I type on is the Dell, the second is the Focus, and I alternate between the two in the audio clip. The difference is a bit less obvious in the recording than it is in person. Hopefully someone can help me out here as I'm kind of confused and am not a huge fan of the sound of the Focus. And yes, they are genuine Alps, not clones. And they're pretty damn clean, too.

I'd be more surprised if they didn't sound different. First, you have two completely different plates and cases. Second, the difference in keycaps. Third, there were several changes to white Alps switches which affect the sound and feel.
The Focus cases are held together at the front edge by plastic tabs. When I rebuilt my FK-2002 three of the four tabs eventually broke, so I glued some stems in place and drilled and countersunk the case for screws. I also drilled through the two locations at the top edge and put screws into the two factory posts there. Doing that completely changed the sound and feel of the Focus. I'm using it as my driver now, and it's every bit as satisfying as my KB-101A. The Dell case is held together by screws, of course, very solidly built from the factory.
Keycaps also affect the sound and feel. I have no idea what a SK-2002 is, but I have a couple SK-0002 boards here. The earlier ones had nice thick double shot caps, but the later caps were thin, and probably pad printed. I have one of each, and they definitely sound different.
White Alps switches are a whole subject in themselves. Very early ones sounded and felt like blues. Changes were made to every part over time, so there's a lot more to it than just pine vs. bamboo. There may be a correlation between mold numbering and internal changes, but I haven't found that info yet.
If you're really curious you can swap one thing at a time from one keyboard to the other to see if it's the switches, caps, or the case and plate. Most likely it's all of the above.

Very interesting, thank you! I guess maybe my Dell's are very early ones and my Focus's are very late ones. I bet there are some big differences in the switches as a loose switch still sounded quite different.
Oh well. Kinda sucks they don't sound nearly as nice as the ones in the Dell, but I prefer the feel. Much less tactile.

I haven't done it myself, but there's lots of info here on swapping Alps/Alps-clone internal parts to fine tune the sound and feel to your liking. Do some searching and reading when you have a bit of time, then play with one or two switches until you find a combination you're happy with. Lots of options on this!
