Same opinion as Irvrobinson - FPB600 is really as good as it gets!!! I used to have a FPB600, and because of my relocation to another country where voltage is 220v, instead of 120v, I had to reluctantly sell it. In my new location now, I purchased 2 years ago a new pair of Evolution 400 monoblocks, and honestly, I haven't noticed much difference, except I still miss how the FPB600 used to make the lights in the room flicker when it powered on, due to the enormous amount of current it drew, which was kind of cool!!!
