I've noticed a slight difference in sound after replacing my BL5000 amp. by a BL4500 amp [because the green display fits the green display of our penta !!!'s better] and vice versa, is this possible beacause they seemed simular in [almost] every way ?!
The sound of the "new" BL5000 have slightly more bass and the "new" BL4500 with now amber display [looks very nice in there] on our bedroomwall, sounds a bit more high-pitched; is this possible or perhaps my ears are deceiving me ?
