It seems no worse than what people pay for stuff on a Linn LP12 (like $10k+ for their new plinth).
@dwette No doubt, the high parts prices seem endemic to this hobby. Sorry for the belly-aching! I do still love my Master Innovation, 8 years into ownership. The "stock" armboards are indeed around $500; $900 was for a blank with a custom hole. Later, I figured out I could just use the hole in a Graham Phantom board lol.
I thought owning VPI tables would be better on this front, being domestic - but nope, not really much better (though shipping is super fast!). And they didn’t have what it takes to knock off my Innovation. At least Clearaudio has the import excuse for prices!
