Model 2270 and 2275 are two of my favourite Marantz receivers. They have a fantastic 1970s sound, look and vibe to them. Will drive anything, although a pair of JBL Century L100s would be their favourite match. Also the 2226, and the 1978, Model 1550 which is an underrated gem. I got rid of most of my vintage Marantz receivers when the prices skyrocketed about 12 years ago. I'd restored them all and quite frankly, I was done with old receivers. Then they kept going up! I think I sold my 2275 for $770 (12 years ago) and I'd paid $75 for it. Now they are selling at over $1500.
I just restored 4 vintage Marantz units for a friend who can't stop buying vintage and I think I'm done again for a while.
