today my little dot MK 1+ finally arrived which is the smallest headphone amplifier in the little dot program and it's right now unmodded.

And I just have to say I'm deeply impressed by the sound of it and currently only listen to it with the Shure SRH840 and can't wait for the Denon AH-D5000 to arrive.

Once I have the setup completed and learn the sonic profile, I will start to mod it a little. I already have the parts here, since they were rather cheap. I mean tubes and opamp cost like 5$ a piece.

What is missing?

I'm a bit unsatisfied with the bass and the highs are a bit missing. But that's more related to my low quality mp3's I think. Still waiting for the DAC and SACD player.

but it's really relaxing to just lay in the dark, have the tubes glow and listen to some Pink Floyd.
