Philipwu, not a dumb question at all. What is dumb is the person who came up with the idea that 15-20% of your system should be spent on cables. It was probably cable manufacturers who brain washed gullible audiophiles to spend that much on cables. I've been in this hobby for 30 years, and you hear all kinds of BS based on no credible evidence. Like some have said, you can replace $2000 worth of cables with another for $250 and get better results because of system synergy.
Unfortunately, there are audiofools who will not consider a component worthy unless it costs above a certain price point. So to accommodate these fools, manufactures will purposely make components expensive by adding bling to the chassis but doing nothing to the all important circuitry. A friend, who is a manufacturer of audio gear, once told me you won't get press or attention unless you make the chassis huge and substantial and charge a hefty sum. It is not unusual for some high end gear with 30-40% of its cost just in the chassis work. So that $50k amp you're drooling over is largely made up of bling that doesn't improve the sound. Clever marketing will claim the substantial chassis is for resonance control,
I know of another famous audio designer who came up with a very efficient component with small footprint, but his customers complained it wasn't big enough. So he just put the same circuit in a bigger macho looking chassis which drove up the cost. We audiophiles often shoot ourselves in the foot with our own stupidity.
