If you are after a bookshelf sized two-way that fills the bass out beautifully, this may be exactly what you are after. With reasonable sensitivity of 88dB, you can drive these with any good integrated amplifier. As with all quality speakers they will reward you with better performance as the amplifier quality and strength increases - up to a point. Power handling of 100w leaves plenty of leeway, and spending as much again on the amplifier as these cost would be quite justified. While the treble is not as detailed as some other contenders in this class, it is certainly very smooth and unlikely to ever get edgy or tiring - great for extended listening in a relaxed mode, never shrill when pushed to higher volumes - which they can do!
