Wow guys, lots of good info, thanks ! Well my system is about as simplistic as one can get. I have the NAD Masters series M33 driving the M3's. Speaker cables are Danny's 24 strand DIY kit with spades and that's it. Pretty complex huh ? The recordings in referring to are just random recordings I have come across while perusing.. namely older stuff from the 70's I have noticed seem to be lacking in a lot of areas compared to some newer stuff, not to say there aren't some really good ones that were produced in that era. I know my room would correct quite a bit if it were finished, however I do have makeshift bass traps 5 foot tall in front corners and 2x4 insulation boards strategically placed about the room, nothing on ceiling as of yet. I know what I need to get done, just need the time to get some time involved measuring, building QRD's, bass traps and absorption panels. I have vested a lot of time in years past to measuring, testing and tuning a few spaces in previous listening rooms just not in my current house as of yet.
