3-Krell Solo 575 XD Mono Block power amplifiers  575 watt Calls A Amplifiers with I Bias technology and Krell Cast  These amplifiers are less than one year old and have been used in a pet  free/child free fully temperature controlled room with a state of the art system. retail price is 11250.each unit They are complete with everything that comes with the amplifiers new and have no damage or scratches. They have been in the same spot on the same stands since they came out of the original packaging. They have around 200-250 hours of playing time.  The price is for a pair 3 amplifiers. I might consider selling only two but it would be at a higher price per unit for only two
