I used Krell FPB750MCX and 450MCX with ARC ref3 and also ARC ref5. It is a wonderful combination. The ARC makes the mids very musical and still has enough details. It is also not to bright. The KCT has a little more bottom extention but the ARC preamps sound better in the mids. You can not go wring with this combination. Krell and ARC are a perfect match and a lot of audio friends use this combination.
Thanks for the great feedbacks. Good to know that the Ref 5 and Krell make a good combination. I have ordered my Ref 5 , hopefully it will arrive in 2-3 weeks.
I am also considering a Shunyata Anaconda CX cord for the Ref 5.
You've made a great choice, don't waste money on a stupid expensive cord that takes electrons to the transformer of the unit. Look at Signal Cable if you think you need another cord.
