Maybe this is a dumb question, or maybe it's been asked before. Maybe I am just derpy, but I can't really differentiate what feels warm vs what feels "cold" / digital ?? I've grown up with digital, I am a big fan of chiptunes and video game music, and I listened to other music on CD's growing up. I listened to some stuff on tape, but I don't really have a tape source anymore. How would you go about comparing for instance. Even if you ran digital music (a FLAC from a CD or something) through an analog receiver that is supposed to sound warm - would the receiver color that digital music in any way? Is it usually just the phono / tape inputs that carry that warm sound, or is it the amp design in general? i didn't buy my SX-636 looking for a specific type of sound or anything, I bought it mostly for nostalgia and its a right proper good unit for its class. But I'd be very interested to try and compare some of my digital sources against vinyl albums I have. If I could understand how and what to look for. My hearing is not the best when it comes to some frequencies (apparently) maybe I just lack the biomechanical filter to really become nitpicky over it? Someone set me on the right track, please.
