I ordered these to go with an Audioengine D1 DAC and a pair of their A5+ powered speakers. I was not sure they would make much difference and was half expecting to return them. Not so. Obviously they angle the speakers correctly for when you are seated at your desk, which is a good thing. Much more impressive though is the improved tonal separation. Clearer mid-tones, a bit more sparkle to the treble and less boomy bass. Like most things audiophile, it's a subtle difference, but I noticed it immediately, so for me definitely a keeper.
