KRELL RESOLUTION 1's comparisons ??

I was looking into a pair of ones and was wondering if they are worth buying,in terms of sonics,value,and/or problems?
Are they sonically worth it...i have owned PMC IB1's(good speakers)but was looking for a little more spl and have recently bought the Resolution 3's and the wife likes the looks.Has anyone compared the sonics,also do thy have any problem factors(such as bad caps,tweeter,woofers,etc.).
Lastly,are they worth it...the PMC's would have cost me $15,000 for MB2's..way over my $5500 budget..??
thanks John
