Ok Ascend folks, here's my latest quandary.
I currently stream music in these steps:
1) TIDAL App on my iPhone hooked up to;
2) Cambridge Audio ID100 Digital Dock, which sends the digital bitstream of the iPhone
to;
3) Marantz SR6003 AVR, using its DAC to decode the digital stream and send the analog
signal in Pure-Direct to;
4) Rythmik Direct Servo plate amp "IN" RCA, which applies 80Hz bass filtering of the
"OUT" RCA, which feeds;
5) Adcom GFA-5500 2-channel amp, powering;
6) Sierra-2's

It sounds pretty darn nice. So my question is.....Would a highly regarded outboard DAC, in this case the Schiit Bifrost Multibit, make a noticeable & worthwhile upgrade over a receiver's built-in DAC? Has anyone made a similar move or know anyone who has and noticed any benefits?

Thanks!
