- It's not how the disc is delivered, but how the dollars are divided.
- Example -- let's say you spend X dollars on a carousel player, versus X
- dollars on a single drawer player. Because the disc-loading mechanism
- on the carousel player is more complicated than on the single disc
- model, chances are it costs a larger fraction of those X dollars to
- make the mechanism. That leaves a smaller fraction left over to spend
- on high-quality circuitry, separate D/A converters, separate power
- supplies, and all those semi-magical tweaks and tricks that
- manufacturers try to convince you make a difference in the sound.
- (Well, I'm convinced. I don't believe advertising or marketing B.S.,
- but I believe my ears and my ears can frequently hear a difference.
- And yes, it frequently does happen that a $600 player sounds better
- than a $300 player with the exact same features. So where does the
- money go? Making it sound better, I'd guess.)
-
- Please, no flames. I realise this is a *very* hand-wavy argument, and
- to suggest that throwing money into a component will magically make
- it sound better is by no means truth. Just pointing out that
- when designers concentrate on the innards of the machine (which
- generally means throwing more money there than on features and fancy
- mechanisms), it frequently ends up sounding better.
