CMA Audio Announces Updated Niimbus US5 and US5 Pro Headphone Amplifiers

The new Niimbus US5 Pro adds an additional balanced headphone connection. Since the 4.4mm Pentaconn connector has gained popularity as a new balanced headphone connection standard CMA Audio decided to add this feature and renamed his popular US4+ as the US5 Pro. All other features and specs remain the same. The US5 also adds the 4.4mm Pentaconn connector along with every other feature from the plus model except for the 256 step relay volume option.
