Innersound Kilowatt Monoblock, how good is it?

How about the Parasound JC-1?

The following link includes a few comments on the Innersound amp as well as a couple others.

The InnerSound amp will drive 1-ohm loads at high power with no problem. The Pass will run a lot hotter and won't be nearly as comfortable with the 1-ohm (better consult Pass). Plus, I believe it will only deliver about half the power of the InnerSound, if that...

I assume these are the later Stradivari Cello's? Adding to the above, are you sure you can drive them full-range with one amp -- however powerful that amp is? Another point is that *I* happen to like Inner's sound (sorry, how else can I phrase it:), but more importantly so must YOU. Don't buy the amp for its 1-ohm driving abilities -- you can factory mod. other amps to do this too...and there are other amps factory -set with that capability
(Symphonic Line's Kraft classA series is also set to drive below 1-ohm, fro example; I've used it in such "applications".)
BTW, for the Pass I would CERTAINLY consult the manufacturer before connecting the amp to the speaker, as Plato suggests. Nice speakers!
