Subjective tastes aside; The Model 1 will offer cleaner, quicker bass, while the Focus 140 will offer bass thats significantly more powerful and dynamic.
Despite spec ratings, the Focus series is pretty easy to drive. Given your current integrated, and the general flexibility of the Focus line, I'd steer you more towards their direction.
