There are volume dependent corrections that need to be made to compensate for the fact that sound perception is level depenedent. Generally, at lower volumes, upper and lower frequencies need to be boosted and at louder volumes, slightly atenuated relative to mid frequencies, in order to maintain the proper tonal balance. TACT's newer "dynamic" room correction uses Fletcher-Munson based curves to make on-the-fly adjustments for every .1db level change. It has made a significant difference in my systems and can be easily compared to their standard room correction with the push of a button. -- Sleestack *headphone:* singlepower sds-xlr at, classe sacd2, hd650 *2 channel:* tact rcs 2.2.xp w/ full aberdeen mods, bel canto oneref. 1000 monoblocks x 4,teac esoteric p-03/d-03, epiphany 12-12s (waiting for my 20-21s), tact w210 corner load subs *5.1 channel:* tact tcs mkii w/ aberdeen power supply, tact boz 216/2200 (x5) w/ aberdeen power supply, tact adc6 w/ full aberdeen mods, denon 5910, bel canto pl-1a, eggleston andra ii (x5), velodyne dd-15, pioneer elite pro 1130hd ------------------------------------------------------------------------ Sleestack's Profile: http://forums.slimdevices.com/member.php?userid=6598 View this thread: http://forums.slimdevices.com/showthread.php?t=26306 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
