Meridian G02 with non Meridian Amps?

Anyone have experience with this preamp and amplifiers from other brands?  I'm considering this preamp as it has a nice amount of connections...would like to know if this preamp was built mostly for the G57 or if it will generally mate well with other amps.  (Possible amps would be Parasound A21, Krell KAV-250A, Proceed HPA2). 

Thanks for your feedback!
