Can't comment on the 7510, but the Caiman vs CD Player's DAC is a similar comparison - as I think I posted before, at first it took me a while to understand that the bass with a Caiman may seem not as strong, but what I actually hear is more tuneful and tighter bass, not just a low range thump or a floundering bassline - much more punchy through the Caiman - which takes a bit of getting used to if it is a new experience.
