Power Cords/ Conditioner/Surge Protectors

OP, do you have a hifi shop nearby?  This is always the best advice given imo: demo some gear!!! Do not buy blindly online.  Find someone close that deals in Shunyata gear or whatever you're interested in.  Those that say power cords and power conditioning don't matter, I'd challenge them to say have they ever tried it in an acoustically treated space with high end gear?  Ofc on low end gear you're not going to tell a difference.  Maybe your speakers should be first though.  I think room and speakers have the largest impact on sonics.  But yes, these all make a difference, sometimes massively.  And the comment on what Pass ships with their products, who cares?  They aren't cable manufacturers and sending a giant audiophile cable would be cost prohibitive.  But to say they don't make a difference is just incorrect from an objective standpoint

As above, "Good surge suppression is a MUST for expensive high-end equipment." -- ABSOLUTELY TRUE.   +1 to willywonka.

@singere:  Yes, you should add a power conditioner to your audio system.  And, yes you should use all  upgraded aftermarket power cables in your audio system.  Happy listening. 

Full home surge suppressor, nary a worry. No dynamics sucking boxes.

Also love the suppressor for .45acp. Neighbors have no idea I am shooting targets in my backyard.

From the bottom of your list up.  

1. Of course you want surge protection to protect your investment.  Power conditioners like Shunyata and Audience have surge protection.  
2. Conditioning produced a significant improvement in sound quality in my system.  Power Conditioners remove noise on the power line from electro magnetic interference (EMI) by filtration.   Good power conditioners also remove noise from ground loops and isolate your equipment electrically from each other so noise from a computer module in a streamer does not enter the audio system circuit.  If you live in an area that has a high population/home density or has industry, conditions are recommended.  I have had improvements with both Shunyata and Audience.  The higher end models give the most improvement.  Regeneration is another option which also reduces noise by converting noisy AC to DC and regenerating it to pure sine wave AC.  Regeneration is recommended if you live in an area where there are voltage fluctuations.  For example, I use regeneration in a vacation home in VT but power conditioning in my permanent home in the NY-suburbs (voltage fluctuations vs noisy mains).  Good regenerators have surge protection.  
3. Good power cords prevent EMI from entering the system.  EMI will enter a system at the weakest point - the least shielded point in the system.  Good cables also have low resistance and high conductivity, improving SQ.  I use WyWires Platinum on all equipment.  Each wire brand has its own sound characteristics, so brand is a personal choice.  

Good luck
