More than once I've come across things in here that seemed strange, perhaps nonsensical and they are used with great success.
For example, a little black box with inductors, transformers and capacitors has entirely transformed my system by lowering the noise floor.
Two big wooden sideways bookshelf looking furniture have cleaned up lower frequencies, widened the sweet spot sitting position and reduced flutter echo.
I heard cable lifters in a friend's system pulled out and replaced, I purchased two packets of them for mine.
Keep your mind open, wallet closed, and weigh it all up, go listen if you can and move forward from there. If you're never challenged or surprised in here, I know I often am.
