Marantz Amp upgrade

[Converge]

Hi all,

Hoping for a bit of direction...

Basically I currently have a Marantz 6003 amp from about 2011. It’s served me well over the years and is still going strong.
But I’ve received a good offer for a Marantz 6006 recently and was just wondering if it’s worth the upgrade or will there be no discernible difference between the two?

Any help would be great!

Thanks for the helpful and informative replies guys! Sounding as though it might be best to stay put with my amp for now and not rock the boat...

Talon, it was the UK edition, which I think is the newest version of the amp!

Lucid, I think you’re right. If I do eventually upgrade it should be to something that is a significant one rather than a rather incremental one by the sounds of it.
