Meridians are amplified speakers, therefore can be "digital", as they can utilize a digital input.
The majority of us use unamplified speakers, which require a separate amp, thus the amp can support digital in, but the speaker cannot...so putting digital in the name is misleading.
I think one of the biggest mistakes is playing the bigger is better game. There is such a thing as too much speaker in a room. It took me a while to realise that applied to "bookshelf" speakers as well. It's so easy to buy that 6.5" MTM with the integrade amplified woofers in the sides, for as much as say a Klipsch reference bookshelf speaker or Energy Connosieur series shelf speaker would cost (of coruse a floorstander w/ powered integrated woofers that cheap would probably have serious sound quality issues...but let's forget that for now)....but if your room is too small, it's just going to cause more problems than solve. This is a classic case of "less is more".
