Never met bigger and stronger Marantz receivers.
The 2216 I have is a wonderful sounding little unit. The 2230 is more powerful with it's 2x30W, but for me the 2216 sounding better. Maybe it's just due to spekers. JBL L19 on 2216, JBL L40 on 2230.
Have worked on the smaller Marantz receivers. They were good performers. Like yours.
