CXA80 could very well be better than 8005 or it may not, I paired my speakers with CA Azure 550 before and it was not a great match, very bright for my liking. So CA was not really in my consideration.I am planning to pair CXA80 with Monitor Audio Bronze 6...I think it will be a nice pair..i had used PM7005 earlier, it was very good amp and i know the Marantz sound signature. and also i auditioned Bronze 6 and i liked it a lot, majority of other FMs and from other forums think CXA80 is anyday better than PM8005,
Do listen to any combination before you part with your Gandhijis!
