After reading up on the 3400, I may be as well to stay with my 2170.
Extra features I see.
More power 2x200w at 8 ohms
Aes/ebu digital input
Built in media server.
I use my Vault2 for media , playing my ripped cds and stream Tidal.
Will not get rid of it as then would lose ability to play my ripped cds so the built in media server on the 3400 is a little redundant for me.
More power...well always nice but I do not feel the 2170 is straining in my system so....
Aes/ebu input...... Do not have anything that has that type of output.
Will wait and see others thoughts and experience with the 3400.
