I know this thread is mainly concerned with ICs but it just so happens that I am currently testing Paragon En. speaker cables against Valhallas. About a year ago I replaced my 10 meter QFil XLR with a similar Paragon, preferring its smoother, somewhat fuller yet extremely detailed sound so this year I decided to compare the speaker cables. I probably have about 15 hours on the Paragons to date so they're still pretty fresh but they are acquitting themselves quite nicely. Overall, if I had to make a choice today I would return to the Valhallas as I find them to be slightly more open and dynamic (the old "...lets go of the notes into free space..." phenomenon) and to have a tad more impactful bass (though possibly less even-handed up and down the bass range). But once value is thrown into the equation it's all Paragon hands down.
