Best vintage Marantz receivers?

My apologies if this is a topic that has already been heavily covered.

I'm looking to get a vintage Marantz receiver. Thus far I've read (in another forum) that any 22xx models are well regarded. Does anyone have anything to add to this, or possibly disagree with it, altogether?

What are the most recommended, or respected, models for amp quality, all vintage models considered?

Thanks.
