I took issue with John VF's opinion that "everything" made the biggest difference. That doesn't make sense. Nor does it answer your question. The Duh! was in answer to John's post.
My comment was just that synergy between all components is more important than the performance of any one link in the chain. And in my experience, that is the case. Beyond that, it's personal preference as to which matters most.
I've had excellent cartridges sound terrible when poorly matched to an arm (AT-150mlx on my VPI). I've had excellent speakers sound bad when poorly matched to an amp (Kef 103.2 on my Fisher x202b). In both of those instances, the cart and the speakers have sounded great in other systems. I've also assembled great sounding systems, and watched them fall apart when putting in a different preamp. A preamp that sounded great in another system. As I stated earlier in this thread, the preamp is more important -to me- in a system comprised of quality components. I can live with many different types of speakers, but I can't live with a sonically dead, flat, harsh sounding preamp. Same with cartridges...but of course, as was the case with the AT/VPI combo, the cart's interaction with the arm spoiled the whole sound. So the cart was very important in that scenario. But you can't say that it was solely the fault of the cart..it was the turntable it was attached to, and to some degree the phono preamp as well. They just sounded terrible together. You can't judge the quality of any component except within system it is hooked to. Run big infinities off of a low powered tube amp? Not going to work. Run Altec 19s off of a big wattage solid state amp? Probably a waste of one of their biggest strengths, their efficiency and maybe not the smoothest sounding amp for that speaker.
