Big Krells Have Vanished From The Used Market

 class A or D  well I own both   NAD -m33 and 23   700 watts

also krell evolution 400  ..I switch back in forth  the nad is the cleanest and pin point imaging I have ever had in 30 plus years of high end audio driving  Kef reference 5 meta,  love the warm engaging sound krell   but love the sound of the nad  one does not need to spend thousands of dollars to to a top performing audio system -would   I buy  amplifiers  in the 25-30k range and expect higher level of sound reproduction  ..no just different  owned them all over the years

..I   was Informed  10 12 weeks turnaround time-  ? dropping my amps off tomorrow

 then i am going to replace the binding post -as to accommodate banana as well

interesting  I never turn off my 23 or 33 and after 90 days its more relaxed and musical ..running with Dirac with no adjustment  just t for room correction, use the correction wile running using krell  cake and eat it to
