the guarneris will not give you deep bass, although the midrange is superb. what about the sonus faber cremona? it's a floorstander( some say it's a bigger version of the guarneris ) . the other option is the vienna acoustics strauss or mahler. i quite like the sound of the mahlers with ARC amps...plenty of deep bass for rock music but still sweet and warm.
good hunting!
