Yeah! Lossless and HiRes are the only acceptable formats to me. I don't understand why peers still use mp3 ... mp3's were okay in the days, when internet speed was slow and storage space expensive. But nowadays? Listen to mp3 with a better equipment, you'll hear the difference.
Concerning HiRes: yes you need an equipment - but you can promote for example the foobar2000 audio player with freeware plugins to a HiRes player on your PC .... together with a quality soundcard, amplifier & speakers. But even without the equipment: the HiRes boom motivates the music labels to release more and more high quality remasters from legendary recordings ... so even without the equipment, you can play the new remasters with a normal flac player.
