I have an FPB 300cx for more than 4 years and don't think about "upgrading" or changing it just because Krell has come out with a new (much more expensive) line. I think Krell is one of the lesser sinners in the upgrade brothel, with the FPB series having been around for 6-7 years and built to last and perform well for at least 20 years. Krell is positively saintly compared to ARC or now CJ with its top pre's.
