There are good quality attenuators that plug right into the RCA cable and even look cool, check out something like http://www.amazon.com/Harrison-Labs-Line-Level-Attenuator/dp/B0006N41B0 >From the description: ".. if the line driver has an 8 volt output and the amplifier has a 100mV (0.1V) to 2 volt range of input level, the gain pots would have to be all the way down. A 12 dB attenuator would allow you to adjust the amp's gain control to about 1/2 rotation. .." -- pablolie ...pablo Server: 3.3 GHz Intel E8600 Core 2 Duo Vista Ultimate 64 Sources: SB3 (4), SB Boom (2), Duet, Accuphase DP65v Amplification: Accuphase E306v Loudspeakers: Tuned and self-built Ceeroy 3 way Headphones: Grado SR-1 ------------------------------------------------------------------------ pablolie's Profile: http://forums.slimdevices.com/member.php?userid=3816 View this thread: http://forums.slimdevices.com/showthread.php?t=55246 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
