A universal remote will probably work for you. For the Oppo, find out who makes the transport and use those codes. For the rest of the system, a learning remote should work. By using the learning function, you will not have to enter codes.
I think I need an audio repeater - need simplicity
About to install a high-end audio system in my office. Problem is it will be behind a structural part of the office where there won't be any direct line of sight to where I will be sitting. Components include a Melody integrated SET, magnum Dynalab 108T triode tuner and the new Oppo 105 when it comes out. Each has its own dedicated remote. I've checked so-called IR universal remotes, but they don't have the codes for my gear. I know Niles makes a few of these, but seems like brain damage to hook up to components that don't provide for this, like the Melody. Any help appreciated.
