It's the power handling stupid (in my best Bill Clinton voice!). I agree with Marakanetz above, I've never seen a 300W/ch integrated amp. Most integrated don't seems to be aimed at those who need lotsa power.
For me, I initially switched from a receiver (aka intergrated with tuner) to separates just so I could get more power (150w into 8, 250 into 4), which my speakers sorely needed.
Nowadays I like having my tube monoblocks, which let me run short speaker wires, and long interconnects. I can now place my audio rack in a bass minima - away from my speakers. Sort of nice.
