the tidal high-res stuff, I'm familiar with, are frequently different masters, w/o the dynamic compression you get on many modern cd's/mp3's which are designed for the ipod+ generation, people with their headphones on, wandering the streets.But I can’t tell the bloody difference between plain old 16/44 and all the new high res stuff at home
but - if you had a choice in a bmw between, say a sunroof, heated seats/steering wheel versus say the HK, or BW option with better speakers, my money would be on the latter.
