What is more important source or preamp?


Oh boy here we go again, but I am just shocked how important the preamp is from my latest experience, but isn't the source more important since without a good signal doesn't matter how good the preamp is.
I know both are important, but would like to hear audiogoner stories about big improvements from making new purchases.
I would rather hear experiences than hunches or theories.

Ivor Tiefenbrun (Linn's chief) says that the TURNTABLE is key, not the cartridge.
I've always bought the best pre-amp I could afford first so I could evaluate any upgrades, when it finally gets exposed as the "weak link" I upgrade it and start over again. While working on improving the source/sources it's helpful to have a familiar constant.
I agree with Ivor-source is most important. Take the extreme: $10k speakers with $50 source. The speakers will sound like crap b/c of crap source. $10k source with $50 speakers. At least your speakers will sound the best they are capable of sounding.
