Hi Penthouse - D,
I have no experience with Shunyata cables but I would give it a try.
In my own system, I have tried MIT and Sensory Power from CD player to Spectral preamp/linestage. From phono to Spectral preamp/linestage, I have used all stock cables that came with the various tonearms and also aftermarket tonearm cables from FM Acoustic and Sensory Power. They all worked pretty good.
From Spectral preamp to Spectral poweramp, I have tried MIT and Gotham interconnects and both work well.
As for power cords, I use MIT AC 2 for Spectral preamps/linestages. For Spectral power amps, I use either Sensory Power or MIT AC 2.
Power conditioners, I use old MIT power conditioners. When I use the MIT power conditioners, I run MIT AC 1 from equipment to the power conditioner and MIT AC 2 from the power conditioner to the wall outlet.
