Since you have a receiver which probably has a decent optical in, and the SB3 has a good quality optical out, the answer is YES you should try a qualitiy optical cable. This cable should be glass rather than plastic. The plastic ones can perform poorly. By using Toslink you gain electrical isolation between your receiver and the SB, and you also are immune to the effects of radio frequencies while in the cable, each which may improve the sound. You may or may not notice a difference in your system/room.
Note that at high frequency transmissions optical cable is more limited, but this is not a problem with the SB3 since it tops out at 24bit/48k which the glass can handle with ease. Co-ax cable is a better chioce if you need to do a long run, greater than about 1.5 meters, since there is much greater attenuation of signal in the optical cable over longer distances. I use a Cardas Lightening Digital co-ax cable or a Harmony Optical One glass optical cable to connect my SB3 to my Channel Island DAC. I dont hear any difference between them, they both sound great. I threw away the plastic Toslink and RCA jumper cables that I used to use, because they both sound dull and flat in comparison. -- Provos ------------------------------------------------------------------------ Provos's Profile: http://forums.slimdevices.com/member.php?userid=9642 View this thread: http://forums.slimdevices.com/showthread.php?t=49666 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
