Dazzdax,
Right now, in the US, they are as follows:
300 B Monoblock: $11,695
845 Monoblock: $14,995
PF 100 Monoblock: $39,995
(These are the limited edition amps using four 845s to produce 117 wpc)
I haven't heard any of their 845-based offerings so I can't comment on the sound.
If you live in Canada, like me, the prices would be slightly different. For all I know, these prices may change after this week's CES.
