I've been looking for a hardware VST host for years and seen a few expensive/buggy pieces of hardware come and go.....and never bought one for those reasons! Then I found out about the Linux equivalent to VST, the LV2 format and straight away bought a Mod Audio DuoX that hosts LV2's.
https://mod.audio/devices/duo-x/Sadly hardware development is no longer ongoing and sales have ceased, but it is available on the used market and software development as far as system updates and new plugins go are ongoing.
The good news is they have a newer model, the Mod Audio Dwarf!
https://mod.audio/dwarf/https://pedalboards.moddevices.com/plugins?random=c223530d0ae7496b8026be40172661a6I have upwards of 700 plugins on my DuoX, Synths (DX7 etc), distortions, modulations, amp sims, modular stuff etc etc. The damn thing even runs Cardinal which is a fully featured eurorack synth with a huge amount of real commercial modules from companies like Mutable Instruments FOR FREE!

I climbed out of the VST hardware host rabbit hole because it goes nowhere, I really suggest you all do the same. Any questions, just type them here and I'll do my best to answer ASAP.
I do like the look of this though
