Krell Evo 402e vs Evo 400 mono and Evo 202/Phantom

Hi,

Martin Colloms raved in Hificritics about the Krell Evo 402e amplifier, as did Andrew Robinson in Home Theater revieuw. I got a great deal for a Krell 400 mono (not the e series however). How compare these to each other.

Have also a deal for a Krell pre Phantom against Evo 202.
Anyone have thoughts about these, please.

They should replace my around 20 years old Krell KSA 150/KRC 2, which, after recapping recently, works absolutely fine.

Thanks guys!
