BTW, this is a hobby whose main purpose is entertainment, so there is nothing wrong with spinning through gear, tweaks, etc. regularly if that is part of the enjoyment factor and budgets enable.
The problem scenario is when one who is a music lover that just wants to be able to enjoy listening cannot get off the equipment "merry go round". The equipment remains a barrier for whatever reason no matter what. I empathize with people in this situation! If it were me, I would seek out someone local with good ears that one trusts to see if some additional expertise can help remedy the situation. Or if you can afford it, rather than buy more gear, hire an acclaimed Jim Smith-like expert/consultant to come in and help with solving the problem.
