Underwood Hifi Cables

Cables are like tennis shoes.
You kind of have to try them on to see which ones fit best.
I don't think there is any way to tell which ones are going to work best in your system any other way.

There is a huge market for used cables, and it works both ways. You can get some excellent deals if you're a buyer, but if you seller, you're going to take a hit.

With the amount I am buying I am getting what I consider a very substantial discount. Gonna do 2 pairs of xlrs since at some point I’m sure i will add dac and tube pre. 
Think I might give it a go. I’ll let y’all know what the outcome is. 
Not a real easy way to just try out cables. Yeah they have the cable store but you are in 10% for every one you try. At least that’s the way I read it. If you are looking at pricey ones that gets to be a lot of money real quick. 

Sorry to say, but buying anything without listening is always a crapshoot.  Does Underwood give a trial period? If not, maybe you are better off going with a used name brand in case you want to flip it later. Then again, Wally does have an excellent reputation and I doubt he wants people coming on here and saying I bought his cables and they were crap. But will you like them? Who knows.

On the technical side...

• they use OFC copper wire, which is far from optimum - look for UP-OCC copper or Furutech Alpha wire
• they use copper plugs, which are better than brass/bronze, but not as good as silver plated copper
• They probably employ a conventional cable geometry, so they will suffer the same noise problems as any other conventional cable on the market

They will perform better than a stock power cable

The DH Labs Power Plus PC would probably be better (at a similar price point) and have some resale value

If you can DIY it I can recommend a vastly superior option, but it requires more  effort  than simply attaching some plugs to a piece of bulk cable
