Good cables for ARC combo

Hello all;
I recently bought an ARC REF110 power amplifier. In the future I would like to match it with a new LS27 preamp. Now I think a better amplifier deserves a better cabling system so I decided to upgrade the cables as well step by step.  .
I am currently using Silver Audio Hycinth ICs, DHLAbs Q-10 Signature SC and different PC from Blacknoise (Goldwire, Blackwire plus) and DhLAbs .
My dealer strongly recommend DHLAbs Revelation interconnectors. They believe that they are superbly detailed and, maybe most importantly, very musical. They even believe that they are better that Nordost Valhallas. Valhallas are out of my price range. Actually I’m considering Heimdall interconnectors as an attractive option but I think Nordost cable can sound a bit cool or dry sometimes. I am not absolutely sure that they will be good for my system.
I have separate power conditioners from an Italian company Systems and Magic for each component. They are pretty good performers. The point is they all require not one but two power cables, one before and one after the filter. Another cable is also required for the power distributor. The reviews say that Shunyata cables are a good option for ARC gear. The dealer particularly recommends Python CX for my REF110. On the other hand my DHLabs dealer underlines the exceptional performance and value of the Red Wave power cord.  
Your recommendations would be much appreciated
Best regards
