Thought I would take some nudes in case anyone was lookin NSFW First listening impressions; Very articulate/ controlled bass. Notice an immediate difference coming from my USB audio interface, the transients are the most noticeable especially with challenging electronic music. When listening to square/ triangle/ sawtooth synths the improvement is night and day. Granted the headphone out from my USB interface is just mehh and my HD 25 SP-II phones still leave something to be desired. Overall though, there's nothing bad I can say about the Liquid Spark at the moment. To the people who say this thing is bright or fatiguing, I can almost guarantee that it's your headphones, not the amp. The Liquid Spark is definitely the strongest link in my chain right now. Just need to get some open backs and see what this thing can really do. Btw, does anyone know the max signal input voltage for this thing? I'm using the line out from a USB recording interface and it seems pretty hot. Just want to make sure i'm not overpowering anything.
