"No matter how good any of the other front end components are, they will sound lousy if the cartridge is not quietly, solidly in the groove." And what component is in charge of keeping the cartridge in the groove? The tonearm, of course.
"and lastly turntable is the least important, assuming it spins at the right speed. It shouldn't sound like anything." Getting a turntable to sound like nothing makes choosing a turntable critically important, it seems to me. Most choose their TT based on how it DOES sound, not how it doesn't sound, because it is so rare to identify a TT that is colorless.
"Percentages are a waste of time. Everything is important, and evenly matched levels (cart/arm/PS) make the most sense. A $500 cartridge on a $10K table? Come on. A $5000 cartridge on a $1000 table? Come on." Is anyone else besides me confused by this paragraph? If percentages are a waste of time, and everything is important, then why not entertain the idea of a cost mismatch?
I apologize for seeming to pick on soko; almost any comment on this subject can be so dissected.
