The Lookup Tool does list Audio 1441; it is a Sony 12/15/20 executor.

I used this upgrade in conjunction with RemoteMaster to find that Marantz CD players use RC5 IR protocol, device 20.   Audio 1189 looks like it should provide many of the functions, and you can of course supplant the missing ones with EFCs taken from RM.  However, the protocol executor used in the upgrade has been superceded by a RC5/RC5x executor in your new remote, so it is necessary to convert the executor type to obtain functioning EFCs.  It is easy to do, but given your disinterest in learning about this, maybe you should just post a list of the functions you need, and I'll supply any missing EFCs.
