Best Power cable around/prefer under $300....

For under $200 you won't beat an Audio Envy power cord IMO.

This makes it probably the only one mentioned you could buy and use several years then sell and not lose money.

In my experience every cable I’ve ever bought used I’ve been able to sell years later and not lose money. Most used cables can be had for 50% or better off new. I’m sure the Master Coupler is ok but there’s nothing special about a SR Master Coupler in regards to resale against other cables.

What is peculiar though is if you look at usedcable.com right now you will see there are 11 Synergistic Research power cables listed for sale....more than double that of any of the 18 other brands listed in their inventory. Makes you wonder why people are unloading them in such volume or why they can’t get rid of the inventory easily either. No opinion here...just stating a fact.

Also, typically, high volume manufacturers, not just cable manufacturers, tend to have much more listings on used market than low volume manufacturers. Similarly, low volume manufacturers, not much available in used market. This is just a fact, reality.

@thyname

Not sure I understand this logic...so this is where all SR surplus used cables go first? Makes no sense. Where does used surplus come from and what’s the difference between garden variety "used" and "surplus used"? lol

Furthermore, about the "low volume manufacturers"....Audioquest has 2 listings, Cardas 1, and Shunyata has 3. Not sure SR (and its 11 listings) is bigger than any one of these companies and certainly not bigger than all 3 combined.

Edit: In fact I just looked up information on SR. They have approx 15 total employees and operate out of a 12,000 sf warehouse. That’s honestly a much smaller operation than I had even assumed. Comparatively AQ reports to have 135 employees.
