Oppo 105 D vs. DAC-transport combination.

In case anyone is still following this thread, I’ll update it.
 I finally got a power cable from Cyrus itself, and, lo and behold, it’s a THREE pronged IEC hole instead of the two hole designed for the unit.  The good news is that it works and sounds great, much better than the cable I was using.  The bad news is that, for some reason, the coaxial interconnect now produces no sound whatsoever!
Fortunately, the optical cable works.
I’ve called Cyrus.

The coax (Morrow)  kicked in finally, but it doesn’t sound as good as the optical.
 Maybe it has to break in more

What a difference with the new power cord.
Hard to exaggerate how much better the Cyrus-Gumby combo sounds than anything else I’ve tried.

 

I admittedly haven’t read through this entire thread, but in my search for ’Oppo 105 and transport’ it seemed to be the closest topic.

I was bored one day & decided to try connecting my old Technics DVD-A10 as a CD transport feeding digital out via both coax & optical to BDP105. I also configured the DVD-A10 for no upsampling to 192/24; strictly 16/44.

My reason for trying was simply out of curiosity but also my desire to extend for as long as possible the duty cycle of the BDP105 transport, since it also doubles & triples its duty for Blu-ray & SACD discs.

To my surprise, the music from CD's came through with an amazingly uncanny three dimensional soundstage that by comparison, using the BDP105 transport did not exhibit as well a three dimensional sound. The DVD-A10’s coax connection sounded slightly better than the optical, but not by much. The noise floor was also noticeably lower & the music just sounded more organic & accurate with respect to pace timing & rhythm.

It got me wondering if the isolation between the two components is a contributing factor; any thoughts why?

Oppo 105 is an SACD player which has multi-channel analog out. If you use it as transport,  DSD will be downgrade PCM to external DAC. So you loose 1) multi-channel 2) more information from DSD.
