I used to be something of an audiophile. Not so much any more. I could quote all the numbers. After a house fire back in 78, I lost over 600 pieces of vinyl, an several pieces of electronics that would still rival what is available today. To this day I would defy anyone tries tell me that a CD is better than some of the first cut vinyl lps I owned to prove otherwise. You're barking up the wrong tree. I am not sold on the iTunes thing and still don't care if my phone is capable of whatever it is you seem to think is a selling point for the Galaxy or any other android phone. I still have the McIntosh 1900 receiver and the Thoren's turntable from then, they survived the fire. I just don't have the vinyl anymore. My point is that I really wouldn't want to think of a phone as being a part of a top end music system and I don't see a phone as being a key component of a system deserving of the quality of sound reproduction I would have if I had the $$$$ to do so. Maybe you would consider storing music on your phone for reproduction of sound, I don't, and I see no reason to depend on a $200 phone to make it happen. If I had the vinyl I lost I wouldn't even think of using a phone to depend on music reproduction. I would in fact view it as some kind of a joke.
Then as a former audiophile, this should get you excited....
See this.....
Astell&Kern and click on the AK 10
If you read through this, you will see that this will provide output tough for an audiophile to distinguish from a big DAC....it has exceptional quality analog output....and...it talkes digital input from a smart phone....the reason to do this with an android, and NOT with an I phone, is that with the Android you can store and play 24 bit/ 96 Hz master recordings...the music you would want to collect with you for your whole life...
Imagine your building up exactly the collection of master recordings you wanted, for your awesome home stereo....You most likely will have a killer DAC taking in the 24 bit( masters) or 16 bit source( CD) and pushing this into your power amp(s).....The thing is, you copy this entire collection to your phone--identically....and no matter what happens to your home or your moving, or traveling, you always have all of your important collection--with you.
With the DAC you plug your phone into, the AK10, you can make a $20,000 stereo sound good, or a 3 thousand dollar stereo sound good...or a $1000 stereo....and this includes plugging in to the Line in on cars with Good car stereos....BMW's. ...AUDI's, etc. Even my Ford Raptor. Playing 24 bit, 96 hz into the Raptor DOES sound better than CD music....you pick up more transients---this being what is destroyed the most by the CD with it's slow 44 Hz sampling.....For others not exposed to the idea of transients before, the easiest way to demonstrate is with piano music....a really good stereo playing a 24 bit 96 ( or 192 Hz) master of a piano solo, in some room in a house.....and a person walking into your house will assume someone is playing the piano --for real....The vibrations in the sound of the piano--the fast transients, just get lost by a CD...so if your evil twin was in a similar house, with same stereo, but playing the same music from a CD....the guests in the house would know that they were hearing a stereo playing the piano....
Obviously, a great deal of music is changed by loss of the transients....though I doubt it would hurt rap or grundge, or heavy metal.....it's when detail makes a difference.
With the Android, you can have all of this, and have the safety and convenience of having a 2nd copy of your whole collection, with you for always.
Which brings me to a rant on why MP3's should be discontinued by everyone, and while we are at this, why I tunes is so defective with it's ties to mp3 /poor quality music.
Fortunately, there are about a half a dozen large sites that now sell 24 bit master format music, in all of the genre's...though they are heaviest in genre's not to poular with a general audience....but, this is changing. Neil Young just go hugely behind this with a big new Hi DEf Music direction. Sony is also about to unleash a huge new line of hi def music....Finally we might get back some of the music quality we enjoyed in the 70's.
