I wouldn't. It's a slippery slope.
Got the SPC108s - ooh that sounds nice.
Oh no needs better sound deadening - ooh that sounds nice.
Oh no - base a bit week, got the DA84T6 subwoofer package - ooh that sounds nice.
Oh no - response across the spectrum a little flat, got HALO 11 for DSP.
Oh no. DA84T6 amp gives very limited DSP control, swapped out for KMT-200 - ooh that sounds nice.
Oh no - Spotify isn't MQA and HALO11 has a dedicated TIDAL Hi-res stream - subscribed - ohh that sounds nice.
Oh no - is that how much I have spent
But wait what if I bypass the speaker loom to exploit spare rear pre-output for direct DSP control of Tweeter instead of current combined Tweeter/Mid combo - STOOOOOOP
Oh no - wind noise from pop top, how do I silence that - STOOOOOOP
