ipod - I hate them. With a passion. Fricken fashion accesories with cr@p reproduction. I do, however, listen to MP3s, ripped to 192 (ewwww-ish) on my phone (rubbish sound - marginally better than an i-pod) and occasionally (longer trips) my sony MP3 player (at 320Kbs on that, since theres space, and it sounds about the best of any MP3 player I've heard). Its a convenience, more than anything. Beats traffic, phones ringing and conversations about utter cr@p in the background of my office and what have you.
I listen to these on Sennheiser CX95s, which are good enough to bring out the best of the sound, but not so good that your just listening to artifacts.
Home -
CD - Very much big time. I listen to CDs on my Arcam Diva CD73 (24 bit, 192Khz wolfson DACs), through my Adam A7s and/or NAD C352 into B&W DM602 S2's.
MP3s at home - Yes. I use Foobar2000 and the DACs on my EMU1616M soundcard to upsample MP3s to 24 bit 96Khz and listen trough the Adams and NAD/B&Ws as well.
While the dacs on the EMU arent [/i]quite as pleasing to listen to as the Arcam, they deliver the goods, and the upsampling works pretty well (not perfect, as I doncluded with A/B/C tests against FLAC and WAV - but suprisingly close). As an aside: I also found that FLAC doesnt sound as good as WAV. I expected no difference, but it lost some punch and authority in the low end compared to WAV).
I also use the following headphones for both MP3s and CDs at home:
Sennheiser HD25-1, RS-140
Future sonics atrios
Shure E4
Blu ray - No. Couldnt give a monkeys. I use my PCs DVD player. I dont own a TV, let alone an HD one (I think my monitor is HD, though). Couldnt care less about it. I'll get one when they are more standard.
Display in general - I use a TFT, and a geforce 8800GT - While I recognise its inferiority in image quality to CRT, I dont really care: It works for me as a display (given my apathy toward displays: they have to be pretty good, but not amazing) and the biggest bonus is 22" of screen doesnt go 20" back, too, which gives me more space in my little flat to jam things that are more worthwhile to me in. The 8800GT is for my (rare) gaming, and it rocks as a display source, even if the monitor isnt that great (its about as good as TFTs get, but like I said; not as good as CRT).
