It's about more than just current and power. I think until you have a chance to properly audition the JC1's you'll never be able to answer your question.
I've owned switching amps in the past, and was very impressed with them - but I haven't heard anything (within my budget) that wants me to replace my JC1's.
It's also not just about better highs or bass performance, it's about the whole. The JC1's do everything very well, and do it in a cohesive manner. It's hard to put into words, but easy to hear.
Can you audition a pair?
