When iMAC -> TOSLINK -> DAC2, the playback is using the CLOCK of iMAC.
When iMAC -> Firewire -> DAC2, the playback is using the MASTER CLOCK
of DAC2.
(1) The MASTER CLOCK of DAC2 is better than cheap computer clock.
(2) Toslink is not a good digital interface = High Jitter\
(3) Even using Toslink to Weiss DAC2, the signal goes through DAC2
superior dejittering circuit. The person who cannot hear the Toslink
different with Firewire, is mainly based on this reason.
(4) Max. resolution of iMAC optical output is 24bit/96kHz
(5) Max. resolution of Weiss Firewire is 24bit/192kHz. |
