You need to get some respect for her Vinyl, then help her, make her understand a phono equalization stage needs to be between the cartridge and any ’line level’ input.
TT, cartridge, alignment of cartridge, stylus are all questionable.
My approach:
1. new simple TT with built-in phono eq (these can be turned on or off. ’ON’ already equalized goes straight to any line level, i.e. straight to an Integrated Amp without a phono stage (most).. OFF must go to an external phono eq, somewhere, that then goes to line level.
Audio Technica Belt Drive, optional eq built-in, cartridge pre-installed, aligned, new stylus. $120. (upgrade TT in the future) (add a phono stage later)

(add self-powered sub in future) (upgrade the mains in the future)
3. integrated amp with remote volume. I like having balance, treble, bass, (manual is fine, remote is very nice) and it is always nice to have tone bypass.
