Oppo 105 D vs. DAC-transport combination.

The main reason I bought a 105 maybe 4 years ago was to simplify my system, and I have ~ 50 SCADs/DD-As (and growing) . I upgraded from a Parasound P3 to a P5 pre/ dac. I tried the P5 dac using a toslink and after significant break- in, I did not notice much of an improvement

About a year ago I installed an aftermarket wiring loom- silver wires to the power supply board connected to a Rhodium IEC. That was a big improvement. Later, I replaced the OEM power supply with a Linear Power Module, another big leap.

I sold the P5 the using the 105 direct to my amps: OK at best on redbook. I came across a Hattor Passive Pre XLR which was a huge improvement, though an impedance mismatch with my amps. I bought a Audio Alchemy stereo amp, but it too was a mismatch, so I bought a AA DDP-1 (DAC/PRE, but just for the preamp. Finally, the music was coming to life. 

For grins I decided to try the DDP-1 DAC using the same WireWorld Toslinkk cable: WOW

Next up was to dust off my decade+ old Pioneer PD 65 CD player, inverted platter with a Musical Concepts Stage 3 mod which included an outboard power supply: Amazing

So, the 105 now idles until I want to spin high rez discs

Replacing the stock power supply with a liner power module (china, huge toroid + incoming wiring harness) takes the 105 to a much richer level

Have you tried using the 105 outs to the Schiit dac? 

Also you choice of power crd and connectors between the trans and adc are likely nt up to the components
