Hi!
I recently got hold of a power amp almost by mistake and now need a pre-amp. I haven't found anything on the market with the desired functionality and an acceptable price, so i am thinking about building it myself. I have no experience with building amps but I have worked with arduinos and raspis.
The first stage of the build would be the line stage for which I have looked at these components:
If I get this to work, then I'd like to install an IR remote, a phono stage and a BT dac to the relay switch. Also, I have two speaker zones (also on the power amp) and need to add a switch to the output for A, B, A+B output later on. It's going to be unbalanced.
I know I'm naive, but as far as I can tell, the components are basically readymade and it's a matter of soldering them on a board and connecting them up. I must be missing something, right? Please tell me this won't be as easy as just wiring the parts together.
Suggestions and critisim is much appriciated

The first stage of the build would be the line stage for which I have looked at these components:
- power supply regulator
- a relay source switch for 6 inputs (something like this);
- either a Korg Nutube (+PCB & JFETs) or Wayne's Burning Amp 2018 Linestage;
- haven't decided (something like this NJR MUSES®72320 volume control chip but cheaper);
- a smartknob like the M5 stack dial to control the relay switch and the volume control.
If I get this to work, then I'd like to install an IR remote, a phono stage and a BT dac to the relay switch. Also, I have two speaker zones (also on the power amp) and need to add a switch to the output for A, B, A+B output later on. It's going to be unbalanced.

You might have a look at Bonsai’s XAtra line level preamp. It is a complete solution Instead of piecing things together. That is what I am currently using and works and looks quite nice.
