Parasound JCM 250

What's the point of it being stable below 1 ohm if an amp has the headroom?  I don't think that I've ever owned a speaker that dipped below 3.7.

Is this pricing model what we should expect post-purchase Parasound?  The price modest difference between this JCM250 and the JC1+ seems to be disproportionate to the large difference in power output and internal parts, etc.  Should we expect to see the next "JCM450" to be substantially more than the JC1+ without changes jusitifying the cost increase?

Originally listed at $15k, then down to $12k, now seeing it list at $9k…? Must be hard to move these
