Conrad Johnson, Krell, Creek integrated amp??

I have eliminated my integrated search down to approx 3 units: Conrad Johnson CA-200; the Krell S-300i; Creek Destiny 2. The Creek and Krell are in $2500 price range. The CJ retails for about $6600. However, I am aiming or hoping to buy used. I have the Creek SE5350 Classic which is very good, but I want to make a major improvement in sound quality. Unfortunately, there are no CJ dealers in my state to audition the CA-200 I heard the Krell briefly but with no solid impression. I have read a few comments about it having some electronic problems. The Creek Destiny 2 is a strong choice, but I have not heard it and only read reviews on the original Destiny........ All advice welcomed. Thank you, Jim
