Koxbox for sure. I used to appreciate their sound and compositions as a whole, but now I can just zone in on each individual part and be in total awe. There's so much going on and yet they've managed to retain such a sense of space. I've on the other hand also begun to notice how a lot of modern releases tend to sound impressive at first, but once I pick through the layers I end up finding each of them very dull on their own. That's one of the main problems with software. It lacks the fat analog textures. Everything ends up sounding thin and lifeless, so people create a ton of layers in an attempt to hide it/make it sound good. Just try and have kick running in Ableton and you'll instantly notice how it's the same sample being played over and over again. A real drum machine will create tiny variations on every hit, and will thus have a natural groove to it. It's just a few small examples, but it makes a world of difference to me. Both as a listener and a producer.
