I just want to say that I have a lot of hi-fi excitement building in me regarding a move I am making to a bigger house. My HT room has been 12X16 ft. for years. For the first time in my life I'll be in a room where the seakers aren't in either corner of one end of a room. My new HT room will have a fireplace AND it's 19X31 ft. So, here are some concerns. My front speakers are NHT st-4s, NHT SB-3s for rear and NHT SC1 for centre. I use a NAD 2400THX to power my fronts (100WPC) and I have an ArcamAVR200 pre/reciever for 5.1 70WPC. W/Boston Acoustics sub100W10inch woofer. In the small room that was more than enough power. But in a significantly larger will I still have the horses to push the air around my ears? I believe so, the audition room I first listened to the Arcam unit at 70Wpc was also quite large and it had seemed to have pleanty of power. Are there any symptoms I might hear of any audible drop off in a larger room? Also, I only just read in forum about matching speakers with amps/recievers/source etc. Does anyone have an opinion about the matchups I have made? NHT/Arcam/NAD? Personally I love it. I think NHT and Arcam try to be as neutral as possible, I guess something in between "warm" "bright" and other adjectives I hear. Not sure about NAD. I welcome opinions and thanks for letting me vent some of my excitement.
