Power Cables - Stock vs. Budget

For $150-175, I would check out. Probably better than new at that price range, in most cases

Here’s my opinion…

A cumulative of 4 crappy power cords won’t make as much positive difference as one great power cable on your amp. So instead of buying 4 garbage power cables at $150 each, I would get the best possible power cord for the total you’re planning to spend and put it on the amplifier and wait to upgrade the rest later.

On a used market:

AQ Tornado or AQ Thunder (latest editions).

Older Shunyata Alpha Helix - Taipan or Python

TWL Seven Plus. Great bargain used and works awesome on the amp and leaves you some cash towards the next purchase. 
 

Audio Art Cable entry level PCs , worth the money

Order Supra Lorad 2.5 with some nice connectors of your choice. One nice thing about DIY is that you have no "cord clutter". This is a highly regarded cable--hard to beat in your price range.

That is a really good question. While I have a lot of experience putting together systems (for me) from $5K to $150K, I can’t answer it. I think I would continue to invest in components for now. I have bought $100 power cords from Shunyata and others and honestly got no improvement. On the other hand the Audio Quest Hurricane ($2K) I put on my amp was simply stunning… a really significant and cost effective enhancement.

What is your system and venue? There is a place to put photos under your ID. This would be really useful to help answer your question. It is really difficult knowing nothing about your system.

I would invest in components until your average component cost is well over $2K. This is a guess.
