I have an all Krell system made up of two FPB 600c stereo amplifiers, a 28c CD player, KCT preamp, KPE phono preamp and CAST cabling. All have worked flawlessly for two years except the CD player. A couple of days after purchasing the 28c, the player wouldn't power up. I called Krell's sales and service departments and they Fed Exed a brand new one to me the following day. Great customer service!
