They get the job done. A bit stiff for small turns like a M/M stack. It will actually lift whatever is on top up at the back. Fixable with a rubber band or hair tie.
Will you notice a sonic difference between them and a cheaper set from Monoprice? Nope.
If you have a soldering iron and 30 minutes you can make a pair to your specs for cheaper.
That said, they do the job and dint take up much space.
Actually, they seem to have switched to a thinner, more flexible cable a while back, so it should no longer lift the Magni up.
Everything else is spot on; Monoprice is cheaper and sounds the same, but the PYST is shorter and takes up less room.
