I am upgrading my home theater - a full speaker package is up next. Source material is provided by Cal Icon MkII CD and Sony S7700 DVD players. A/V receiver is Marantz SR8400, with MonsterPower HTS5100 power conditioning. Music will be close to 50% of the mix, and movies from DVD the other 50%. Listening area is 27' by 21' with a cathedral ceiling. I've identified these possibilities from local dealers: 1) Polk RTi - RTi10 fronts, CSi5 center, FXi5 surround 2) Klipsch Reference - RF5 fronts, RC7 center, RS7 surround 3) Infinity Beta - Beta 50 fronts, 360 center, ES250 surround 4) Monitor Audio - As wildcard, the new RS Silver series Ideal speaker will mate well with the SR8400, and showcase the best of the source components. Neutral sound adding least to the recording is desired. System volume will be on the moderate side at loudest. I'm seeking good advice before taking the $2000 - $2500 plunge for the speakers. What here has worked well and stood the test of time in your system? Any pitfalls with one of these brands?
