@jonwolfpell Thanks, I think its just a loose IEC connector on the cable. I am sure the electrical tape would work great to keep it tight, but it would just annoy TLS out of me to have to "patch" a $1200 power cable to get it to fit snug. And its not the component because it feels the same all other components I own. My Primaluna Preamp, it would basically fall out if not propped up and the $500 Shunyata Venom fits very snug with a defined click to know it's inserted. 

@audphile1 I was going to order the Neptune Diamond when I ordered my amp. I love Purist IC's and speaker cables, I just have not tried their PC's yet.

Just got off the phone with Synergistic about the loose IEC. They said I could send it back for evaluation and they will repair it if necessary. No thank you. I am not going to send a $1200 PC that was defective out of the box, back for repair. Nope. This Synergistic relationship didn't even get past the first date. Sorry for TMR, but I will setup a return and refund through them and look at something else.

OP

Just return it. you are better off with other brands. I for one, like the Shunyata line after a few trials. 

I have the Pass Labs XA60.5 mono blocks. I initially had Synergistic. (I forget the level). Then I did a big shootout between: 

1. Shunyata Research Sigma NR v2
2. RSX Technologies Beyond Power Cord
3. Audioquest Firebird HC
4. Synergistic Research Euphoria HC Level 3 Atmosphere SX Series

I like the RSX Beyond the best. 

C13 Secure Sleeve with Tab - Yellow 

For loose IEC C13 connectors I bought these C13 Secure Sleeve with Tabs. For $0.80 each. It was the least expensive audio purchase I’ve ever made that works very well and I’ve had to use them on a few of my power cords. You can also get them in black. I actually prefer the yellow as they’re visually more distinguishable to see the depth of fit and how it seats in the female socket. Put them on the IEC C13 connector first and press the face of the IEC C13 connector onto a flat surface until the C13 Secure Sleeve is flush with it. The tab ends should be facing out of the of the female C13 Socket.
