day 2 of listening now i can see how people say tubes are nicer to listen to that is for sure. the midrange is sounding great and like they say that's what humans are used to hearing, or are familar with. really great total listening experience. sounds more fluid and natural. drums sound better, vocals sound better, i think just everything sounds better. highs are nice and pleasant and there's more of an open sound. which then leads to thoughts about the sound stage or imaging. much bigger, wider and better sound stage now. bass is great ofcourse too. dang i'm listening to jack johnson's new cd now and just can't believe how nice this is. with the guitar plucking and so on i can see how people describe the sound as organic. bottom line today it's obvious why people like tubes.
