Ripping and burning audio CDs sounds like disc media to me, but never mind.
So you're suggesting iTunes 9 will allow you to rip/burn Blu-Ray discs into iTunes??? LOL. Not in a million years. The industry would crucify Apple. Apple hasn't even dared to let DVDs be ripped into iTunes. I have to use things like DVD Decryptor (Windows) or MacTheRipper (Mac) plus Handbrake (both) to achieve that effect. Don't get me wrong. I would love if Apple would offer ripping services directly in iTunes. I simply don't believe anyone has that kind of clout to implement and get away with something like that. CDs generally aren't copy-protected and they've been copied so long no one even notices anymore. The industry has embraced "digital copy included" programs that simply give a code to download a digital/mobile version from someone like iTunes. That's fine and dandy for near-DVD copies in iTunes, but they generally do NOT have Dolby Digital 5.1 soundtracks with them which means they SUCK. My own rips have DD5.1 plus commentary tracks even. There is no reason Apple could not include them so it's Apple's fault.
So why not get rid of at least some of this overlapping/redundancy and merge DVD/Blu-ray playback with the QT Player? Both are video players with fullscreen capabilities and transport controls. The fact that one plays streamed or downloaded files and the other plays discs is irrelevant. I mean, what's the alternative if they plan to add Blu-ray support? Should they keep the name DVD Player? Should they rename it to Disc Media Player? DVD-now-featuring-Blu-ray-Player? Meh.
I would agree with you (I tend to like all-in-one functionality as it's easier to maintain and control everything from one centralized database), but there is a very large contingency of Mac users that think iTunes is already WAY too bloated for its own good and is trying to be too many things for too many programs and has become slow, bloated and bug-ridden in the process and has updates coming constantly to address them. These people would prefer the current iTunes be broken up into a bunch of little programs (i.e. iPhone get its own program to control/update/sync it), etc. I think that could be done and iTunes could still be the control panel (i.e. the programs talk to each other and share information), but that would just make for MORE updates (imagine seeing DVD player, iPhone Control, Application Center, Radio World and iTunes all in the software update thing every other week. It'd get MORE messy, not less, IMO).
And the great irony with regards to dynamic range is of course that due to the loudness wars, all music released after the mid 90's is brickwall mastered. We have 24- and 32-bit audio, but we've never needed that resolution less because the brickwall-mastered content only uses the top 8 bits or silence.
Sadly, that's very true of pop/rock/rap/hip-hop music, although it's called dynamic compression. The goal is to make the music "loud" for radio because "loud" always gets better ratings/attention/whatever on the radio than more dynamic stuff. This is partly due to the fact the car is on average a noisier environment than the home and most people do most of their listening in the car or with headphones, etc. It's ironic too because there was more of a "need" for such things in the 1980s and the '80s and earlier were much better behaved in their mastering techniques. Although another problem existed then and that was most material was mastered for the LP and thus sounded anemic and crappy on CD and thus we saw the vast remastering for CD process while the vinyl folks claimed that CDs sounded like crap compared to the LP. That WAS TRUE to some extent, but it wasn't due to the limitations of the CD medium, but had everything to do with the mastering process.
What's sad is today dynamic compression can be done at the radio station on-the-fly without having to butcher the actual album recording, but sadly they compress the heck out of music more today than ever. Some albums get it worse than others and some are so badly butchered they actually CLIP LIKE MAD (e.g. Take the Red Hot Chili Peppers album "Californication" and just listen to it. It's so compressed (no dynamic range) that it's almost flat sounding and worse yet, it clips like MAD all over the place. In short, it sounds AWFUL and that's sad because it has some of their best songs on it. The thing is almost NO ONE NOTICES. And that is because most people have the worst sounding crap excuse for audio equipment you can imagine. And it's not getting better. Places like Best Buy are taking over towns smaller shops and where Best Buy at least used to have listening rooms (albeit poor ones, IMO) for full sized loudspeakers, they now have gotten rid of them in most stores to make room for most flat-screen TVs and the such (TVs used to take up like 2-3 aisles there and now they take up 1/3 the store). The point is you have to go out of your way to even FIND (let alone listen/preview to in a good environment) good speakers these days, let along convince people they NEED them. Sadly, most people think Logitech computers speakers are GOOD SOUND (shakes head). I've had people almost soil their pants listening to my modified Carver ribbon setup. They still don't think they'd want to pay that kind of money to get good sound (or more likely their wives wouldn't let them keep them anywhere in the house due to their size). Even so, it's easy to get caught up in the high-end audio snake oil because there's a fine line between art, science and nuts when it comes to hi-fi. The high-end knows the good equipment, but they also believe in nonsense, so it's a double-edged sword. They waste money on things that don't matter and look down on others that don't have that stuff. It's a very snooty environment. Many Mac fanatics can be snooty, but some of these people take it to a whole different level.
Of course, if you like classical type music or even jazz, there ARE a lot of very good quality recordings out there and many are available on SACD. While SACD is largely overkill on the playback end, the multi-channel version is nice for live recordings if you have a really good surround setup. More importantly, it usually means the people that are making recordings available for it are paying attention to the quality on the recording end of things, where it matters more than anywhere else. So SACD type recordings DO typically sound better than an average CD, but it's due to mulit-channel and well mastered recordings more than the playback medium. A high quality SACD master in stereo that is then mastered properly to CD will sound just as good.
Everyone, including hi end manufacturers know that nobody hears beyond 20k. But if you sample at 192k you can use better filtering and jitter goes down for majority of the DAC's out there the higher you go. So it's for lower jitter (which is audible they say) and better filtering.
"Which is audible they say" is my point in a nut shell. "They say" you can hear these kinds of differences, but can YOU? Most just believe what the high-end magazines say as gospel and yet magazines have a reason to support high-end DACs and jitter reduction equipment, etc. etc. because those are the people paying them big bucks to advertise in their magazines. That's just a fact. I remember and incident back in the late '80s or early '90s involving Stereophile and Bob Carver and his "transfer function modified" amplifiers. Engineering states that a transfer function describes EVERYTHING there is to know about a given system so long as it's written correctly. Bob modified reasonably priced amplifiers to sound like ones that cost a lot more by matching up their characterisitics little by little until they had the same transfer function. Stereophile admitted in a blind test that it worked, but when the actual factory product came out, they gave it a bad review, saying the magic was somehow gone, but with no proof or testing to confirm anything. In short, how would they sell ads for $10,000 amplifiers if this one that costs $1200 sounded identical to it? In a business sense, they would shoot themselves in the foot. If some company pays them big bucks to advertise magic jitter reducing green markers, they have every reason in the world *NOT* to test that product or give it a bad review because it keeps the money coming in. You'd see things like, "I don't know how it does it, but it DID SOUND BETTER to my ears". And how can you question an opinion? You cannot. That's just a short sample of the problems of the so-called "high-end".
About tweeters which go up to 50k, ofc nobody hears the extra range, the only reason is that a tweeter which breaks at 20k sounds (usually) worse than a tweeter which breaks at 50k. So since most tweeters deal with the range 4k-20k you are hearing all those 16k range at better quality if you use a tweeter which breaks at 50k.
Um...no. You can TEST response right up to 20kHz. Most people buying that gear have their hearing fall off around 15kHz yet they are the ones making wild claims about super-tweeters. Will going to 5Hz improve response at 30Hz? No and it might just screw it up royally sine the requirements for the drivers in those ranges are very different. Besides, less is often more. My ribbons cover from 250Hz to 20kHz. There are no crossover aberrations (that even the best conventional loudspeakers cannot fully eliminate) along the way beacause there are no crossover points. Carver sold the AL-III for $2000 a pair. Genesis used the identical ribbon from Carver in its $50,000 a pair Genesis II with a different cabinet and woofer. Was it actually worth 25x the price? I don't think so, but I'm sure many did as they were Class A Stereophile reviewed. Stereophile would not review the Carver speakers after the first prototype so I guess we'll never know their thoughts. It was not in their best interests to compare $50k speakers to $2k speakers when they used the same drivers.
About AAC 256 vs studio master at 192k I have no clue if the difference is audible. I had a 15k$ high end stereo and I tried 256k mp3 vs CD and couldn't hear any noticable difference. But a 15k$ rig is not a true high end. When you are listening to music with a 500k$ rig I'm pretty sure you'll be able to hear the difference.
So are we talking about "high end" as in high end PRICE or high end SOUND? The two are not necessarily related in those ranges. As I've said, there is a LOT of snake-oil being sold in "high end" audio and most of it is just that, nonsense. Once you get to a certain point in speaker quality and have ample power to drive it, your money is best going to be spent on treating your *room*, not buying $20k DACs that sound identical to a $5 DAC in a blind test. Listening rooms can have just as much if not more effect than your loudspeaker on the sound you get. A $50,0000 speaker in a bad room can sound worse than a $500 speaker in a good room. It doesn't take much to screw up frequency response (actual room plus speaker) or get standing waves, resonance, etc. These Carvers sound better in my current house than they ever did in my old one. This house has much better room acoustics to start with and I damped out most of the remaining problems. Downstairs, I have a very dead room and made a home theater with a mere $2500 worth of speakers. But these speakers are +/- 1dB from 80Hz to 27kHz. I've seen speakers that cost 100x that price that had +/- 3dB response in the same range. That's just one measurement, but it's an important one. Of course, how the room then affects that response is just as important. OTOH, the truth is most people prefer speakers that are NOT flat. They want inflated bass, etc. and that's why graphic equalizers became popular. Even Genesis offers a high-end "sound palette" to color their sound to suit your taste. The worst part is that you are the mercy of the recording itself, no matter how good your rig is. The Red Hot Chili Peppers Californication album will still sound like crap on a $100k rig as they do on a $1k rig because the album is screwed up on the mastering end with no dynamic range and clipping. It actually often sounds better on cheap systems that mask the problems it has. Many pop/rock albums are that way. Very few are very good recording quality. I used to maintain a web site that rated the sound quality of rock albums in addition to their musical content. Very very few got anywhere near the "A" quality range for sound. Ironically, people will say something like Pink Floyd's "The Wall" is too quiet and not dynamic, when in fact it is just the opposite. It's VERY dynamic and so you have to turn UP the volume (it plays in the noise floor; you cannot make louder louder than maximum, so the more dynamic albums are quieter sounding at the same volume settings as a less dynamic album). It was analog mastered. It STILL sounds better than most albums today because it's not compressed to death.
Of course, if you like classical, you'll have little trouble finding good quality sound recordings of your favorite classical music (the performance is another issue).
But for people listening to music with (even high quality) earphones, they are only fooling themselves if they think 256k AAC sounds worse than a CD.
Actually, high quality headphones are more revealing than even the highest quality loudspeakers because it takes the room out of the equation entirely.
And you are right about speakers ofc. A 500k$ speaker is night and day better than a 100k$ one. About driver units of speakers though, they are the least
Actually, it's not likely to be night and day better. This is due to the law of diminishing returns. The more you spend on the high-end, the less results you will get. You can get a system that is 95% of the way there for $5000 if spent wisely compared to a system that costs $50,000. You're getting into the range of small improvements. A $10k DAC probably only sounds marginally better than a $1.50 DAC (if anything at all). That's because the differences are so small on such items. That's why I say speakers (which does include their cabinets BTW) and room treatments are the primary areas to spend money. Of course, you need clean power to the speakers for a given load (some speakers offer easier loads than others and this has nothing to do with price or quality), but the idea that a high-end amp is good for the sound itself is a misnomer as amplifiers should be completely neutral. Vinyl aficionados think they sound better than CDs, but in reality a lot of analog gear has euphonic distortions (even-order) that make them pleasant sounding just like a tube distortion effect for a guitar sounds pleasant. That doesn't make it ACCURATE. There's often a very real difference between "pleasing" and "accurate".
important part of a speaker if you ask me. Since a 500$ speaker can use the same midrange unit as a 30k$ speaker but the midrange will sound much much better on a 30k$ one. The enclosure usually is where it most matters. Drivers, except tweeters, are pretty much the same as they were 30 years ago.
I've seen quite a bit of progress in driver manufacturer. Mid-range is all important. You do realize there are types of drivers out there than the piston-box woofers and mid-ranges and cone type tweeters that you see on "typical" loudspeakers, right? Check out Magnepan for planar, Martin Logan for electrostatic, etc. Apogee used to make some nice ribbons and Carver once made the famous ribbon for the Genesis speakers. Not everything has been a piston over the years.
