I know that people (rightly) mock the world of HiFi cables and the pseudoscientific bordering on fraudulent claims made for them. But this is maybe the best £20 I ever spent on music.
When I first used these, to connect a CD player with a midi system (all in one HiFi midi, not computer music midi, youngsters) and replace the skinny phono lead in the box, it was a revelation. More detail and clarity in the sound like I hadn't even known was there. That extravagance was akin to renewing the whole of my music collection to date. Everything sounded better.
Now feels like a kind of milestone. The CD player (same one) is seriously poorly, may need replaced. So I finally swapped the good cables onto the HiFi berry digital player and once again, the full range, new sounds in old records.
So yeah. Most cables are oversold nonsense. But this one is amazing.
