I need some advice on short notice. There is the Little Dot MK IV SE Headphone Amplifier. I'm wanting to buy my first tube amp, but I don't know if this would be a good one. My concern is that my headphones are all fairly low impedance and I know that amps might not always be a good match for every pair of headphones. Right now I have the AKG K240 MK II, Sony XB 1000 (for which I think I need more power to get better bass response), and I just purchased the AKG K712 Pro (I haven't received them yet). Now, I'm just driving everything with my Focusrite Scarlett 2i2 USB audio interface plugged into my home computer.
Does anybody have experience with this amp and maybe my headphones? I this a good buy? I was thinking of trying the Valhalla from Schiit Audio but this opportunity presented itself. Which amp is better? I also have a pair of AKG K240 Sextett studio monitors that I've had since junior high school. They're pretty old, but still sound good.
