PLEASE be very careful. OdB at HF will DESTROY your speakers HF unit. There is nothing wrong with your speakers, cables or ears. If you can hear anything at 15kHz consider yourself fortunate to have good hearing. Please do nothing to change that! I'm sure the spec for your speakers is realistic, but don't confuse frequency response with power handling! FR is NOT measured at 0dB. Most people prefer a gently rolled-off HF response. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal... ...SB3+TACT+Altmann+MF DACXV3/Linn tri-amped Aktiv 5.1 system and some very expensive cables ;o) ------------------------------------------------------------------------ Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=38842 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
