KRELL FPB 350mc mono blocks, BEST of the FPB design

i can not find a flaw on either of the two KRELL 350mc mono block amps. Rated 9 out of 10 for age only. These were purchased new from a man in MASS. 2001 May. Then sold to a man in long island, N.Y.. Then i bought them from him in August, 2009. I don't know the duration of time between the 1st and 2nd owners. The 2nd owner sold them to me because he was moving to a smaller apartment from his home. They performed perfect for me. I have sold off my other components and have only these amps now. I therefore can not audition them as i have no means. All original box, manuals, and packing. The price is firm at 5800 do to condition and originality.
