Hello, I'm willing to build a small audio system. It's mainly for enjoying FLAC audio in my room (about 7 x 15 feet or 230 x 460 cm). Requirements (subject to changes): Channels: 2.1 Audio power: 50W I'm considering the following architecture: Here's my questions: Architecture 1) Is this a good setup? Is it a overkill for just 50W? What do you suggest? Simply a receiver? Components 2) What brands and models do you suggest? receiver preamplifier amplifier loudspeakers cables and other parts Cost 3) Roughly, how much a setup like that (or like your suggestion) would cost? Unanticipated concerns 4) What are the most important technical details I'll have to pay attention to? (eg. impedance has to match between the subsystems, loudspeaker has to support x% more power than the amplifier, etc) If I said something wrong, irrelevant or simply forgot about important things, please pardon my ignorance. I'm completely new in this subject. Thanks in advance!
