Hello everyoneI'm looking to buy a used connect amp, days ago I found one with thesn 1308 00 ......... and thanks to you I discovered that it was a 1st gen.now I have found one with the sn 1804 5c ....... can you tell me if it is a first or second gen.?Thanks for your help

1804 will be a gen2

 


ZP120


 


1804 of the serial is the YYMM of manufacture so 2018 makes it Gen 2 as cutoff for Gen 1 was in 2015


That’s a CONNECT:AMP, not a ZP120, based on the label. Granted, minor difference.


 
Thanks for the help. but what changes between the connect amp and the ZP120?

Initially, only the name, if I recall. Later on, different chips on the inside, including a memory boost for the “gen 2” version, which may or may not have had a CPU boost as well. Sonos doesn’t publish any of this information, so it’s hard to be definitive.


Perfect  thanks everyone again
