Hi guys, reviving this thread since it’s precisely my need. I’ve found many other answers in other threads and elsewhere but it’s still unclear.
Like the OP I want to compare few amps I have around, and some of them have tubes (I understood they should always have a speaker load).
What is unclear is: do I need a switch for the amp input and a switch for the amp output?
Meaning switching RCA signal between both amps, and in the same time switching speaker signal from both amps, to the same speakers.
All the boxes I've found are doing only one thing at a time.
For ex
RCA box:
Or
speaker box:
Is it ok to only use the speaker box, feeding both amps with a simple Y all the time? Even for the tube amps?
The thing that makes it harder is that I also have to switch dsp settings between both, as it’s active and I will compare only a specific bandpass that I would have corrected upfront to match.
Right now it takes me few minutes to swap: power all amps OFF/unplugging/replugging rca & bananas/dsp change/all ON, with some care to not mess up.
Best would be something that does all, with a remote, but I’ll use what I find.
