I'm not really an audiophile, but I do like music.
I have most of my music on my computer now.
When I started this I did some experiments. I'm use a Mac
so iTunes seemed the obvious music player.
I tried 128 kbps mp3 - yuk! I tried 192 kbps mp3 - hmm not
too bad but I could still tell the difference between it and lossless on some
tracks. 256 kbps mp3 - I couldn't tell the difference between it
and lossless on the tracks I tried. Somebody told me LAME was
a better mp3 encoder, so I tried it, and they were right. It does
a better job at 128 and 192 than itunes does, but I could still
tell the difference between it and lossless. At 256 I could
not tell the difference between lame, itunes or lossless.
Obviously I couldn't compare every single song.
So, I standardized on 320 kbps itunes generated mp3s.
My system is fairly resolving. Benchmark DAC1 to either Senn 650
or B&W 703. Last time I checked I still could not tell the difference
between 320 kbps mp3 and lossless on the few samples I tried.
I could however tell the difference between the DAC1 and my
old CD player. I don't use the CD player anymore. Sometimes
I will still reach for an LP (eventually I'll get these
all digitized, and will probably even less often use anything
other than my computer as my player - as an aside, I keep
my ripped records at losslesly compressed 44.1x16 because
they take awhile to do - I wish I had kept some of them at 96x24.
By comparison CD's are fast and easy to rerip).
Some people say disk space is so cheap that it is silly to use
a lossy format. There is a good arguement for this. But I figure
if I can't hear the difference between 320 kbps mp3 and lossless,
which takes about twice the room, why use the extra space?
I have about 60K songs which takes about 600GB of space in
my library. I have an extra copy as a backup, and I have a
third copy in my office for offsite backup and for use there.
If I was going to redo everything lossless I'd have to buy
another 2 TB or disk. That is not a negligable expense. I could
use that money instead to buy more music
