About the cables

Can you somehow switch the unbalanced technology into balanced with a part, so if I'd use unbalanced cables as example, but in the chain it would be converted to balanced, then I could keep using unbalanced cables then? It'd be a converter plug that'd be plugged into an audio-interface as example and then it'd be plugged into the unbalansed cables and it'd become balanced connection then. Possible?

A little ai understanding may help you.
Interchangeability of Balanced and Unbalanced Cables
General Compatibility
Balanced and unbalanced cables are not fully interchangeable, but they can be used together in certain situations.
Balanced Cables: These have three conductors (positive, negative, and ground) and are designed to reduce noise, especially over long distances. They are typically used in professional audio settings.
Unbalanced Cables: These have two conductors (signal and ground) and are more susceptible to noise. They are best for short distances, like connecting a guitar to an amplifier.
Connecting Balanced to Unbalanced
Balanced Output to Unbalanced Input: This connection usually works without issues. However, it may introduce noise if the ground connections are not managed properly.
Unbalanced Output to Balanced Input: This can also work, but it may require careful handling of ground connections to avoid noise.
Important Considerations
Signal Integrity: For optimal performance, it is best to connect balanced outputs to balanced inputs and unbalanced outputs to unbalanced inputs. Mixing them can lead to degraded sound quality or noise.
Device Compatibility: Some devices, like mixers, are designed to accept both balanced and unbalanced connections. Always check the specifications of your equipment.
Conclusion
While balanced and unbalanced cables can be used together, it is essential to understand their differences and the potential for noise. For the best audio quality, use them as intended.

Yeah, this requires one single passive part: two coils close together with a iron core. It's called a transformer. You find them inside stage blocks and passive DIs.
Example: https://www.lehle.com/lehle-transformer-hz-l
But what benefit do you expect? I've tested a 20m long unbalanced cable, very cheap RCA home hifi type with several adapters to fit three together and convert to/from 6.3mm, compared to a 1m balanced patch cable. No measurable difference.
Your audio interface should accept both balanced and unbalanced. Otherwise get another one.

Thanks for the answers. I just wanted to learn about this and just ask the possibility about a new method. Indeed in this case I'm anyway gonna buy new cables that are balanced i.e. from Thomann for 10€ (3 meters). But in the sciencewise this method would save lots of money for the electronic /electricity companies some kind of maybe. If you'd use adapter in the end of the chain and then connect it to ending device some kind of, would it be bananas then? Ok a German joke. By the ronsyydijajka. Cnd then. Võit.

Connecting unbalanced cable to balanced input often means loosing 6 dB of signal level
- and that's pretty much it, unless very noisy environment and need supression of that noise
- what is called "common rejection ratio" in differential amps tells how much surrounding noise will be filtered. Often 85-90 dB or so.
Good quality shielded unbalanced cable is usually ok. That is where to put your money.
- if manufacturer tell capacitance per meter it's rather serious manufacturer
- for normal keyboard stuff like synths 120-130pF cable would be ok
- since this gear usuall connect with 10-50 kohm inputs
- I find Klotz really good stuff, but Roland interconnect cables RCC are good too.
Best quality cables for electric guitars being high impedance inputs in amps best quality is around 60 pF per meter. But all unbalanced then.
A lot of balanced gear though, sense if not positive and negative on the inputs, thereby unbalanced cable, and adjust according so no loosing 6 dB level.
- it becomes a short to ground on one cord
- I think RME call it servo controlled or something that compensate for this
Note that balanced input demand hi quality differential amp that does not drop quality of signal detecting it.
- a positive signal is to be exactly the same but phase shifted to be negative on the other cord
- external noise will add to both the same amount, and thereby differential amp reject that noise entering signal
I discovered building and modifying a DAC board, that use dual ended differential output chip, to find the differential op-amp it fed did not do a good job but create a lot of THD in upper mids. So just removing op-amp and go single ended signal was lovely all the way. Loosing 6 dB was not a problem, todays amps have very low noise floor.
- so putting a lot of stuff in between to make balanced might create worse sounding audio
High quality unbalanced cables are most often sufficient.
