Anyone compare the sound quality on both these units?

The Little Bear B4 is a portable tube headphone amplifier, that runs off it's battery, and does not function while charging.
Where as the Bravo Ocean is AC powered.
What are your uses for this headphone amplifier?

 

[JIMMY16]

I'm currently using the little bear b4 as a desktop amp (6 hours at time per charge). I have a disease called upgraditis but on a budget.

What sources or DAC is the Little Bear B4 connected to?
What headphones or IEMs do you have or plan to buy in the near future?
Right now I'm assuming the Bravo Ocean will not offer any noticeable improvement.

Your probably right about "little improvement" the amp would be connected to an el dac and used primarily to drive 6xxs. maybe sometimes creative aurvana lives.

For the 300-Ohm HD6XX, some might recommend getting the Bottlehead Crack tube amp, with Speedball upgrade.

Might also check out Drop (formally Massdrop), get a tube amplifier with a balanced output jack

And get an aftermarket balanced cable.
