FS: Headphone Rig

I had setup this Headphone Rig when I was living in an apartment. I was looking for both good sounding and fun setup and settle for Ultrasone Pro 900 headphone paired with Little Dot 1+ tube headphone amplifier.

Utrasone Pro 900 is closed back design and features S-Logic design that produces wider soundstage. These headphones are famous for producing very deepest bass. They produced a well balanced and Lush sound when paired with a tube headamp.


The Little Dot I+ is a hybrid transistor-vacuum tube headphone amplifier, which combines the smooth, musical sound of tubes with the high output current of transistors. The vacuum tube stage is run in Class-A, the MC33078 operational amplifier (socketed) provides voltage amplification, and BD139/BD140 transistors serve as output buffers. The Little Dot I+ is specifically designed and optimized for driving low impedance headphones that require high current to perform to their full potential.
