Djiti,
Comparing the 1.4's to the c1's on the basis of percentage points is a rather subjective exercise. Suffice it to say that the c1's are considerably better than the 1.4's in every category. Do the 1.4's go lower in bass? Yes, but I feel the bass is just a bit overdone, to the point of muddying the mids. This is not a glaring problem; just something my ears picked up. That said, the Krell will probably address this the best of the amps you are considering. If you can't afford the c1's now, go for the 1.4's. If you buy used they will hold their value pretty well when you go to sell them on Audiogon.
