1) I believe that every component matters significantly enough that no one component is the most important
2) While cables are not components per se, they generally help make or break a system
3) There are lots of fine business/marketing/economic reasons for cable pricing, but the pricing is bordering on obscenity
4) Very expensive turntable systems will outperform cd systems (that is different than saying all or most turntable systems will beat all cd systems)
5) Tubes are not inherently superior to solid state
6) Acoustics do matter, but the human brain can also do a pretty good job compensating in most real life environments
7) Isolation matters for source systems (e.g., cd, tt)
8) Everyone's ear is different and preferences are different -- there is no best for everyone.
9) There will always be great music and great musicians
10) The music companies will be better served by lowering their prices.
Great thread!
