Meridian Prime Headphone Amplifier / Prime Power Supply Review


Meridian Prime Headphone Amplifier / Prime Power Supply Review Highlights

An incredibly compact and beautifully designed USB DAC and headphone amplifier from Meridian. Costing more than double the recently reviewed Sony UDA-1, the Meridian Prime offers similar functionality, sans the built in speaker amp, but with much higher performance. It may be small, but this little guy manages to power Audeze planar magnetic headphones with a clean and neutral sound.

Introduction to the Meridian Prime Headphone Amplifier / Prime Power Supply Review

With 25 years of experience in DSP Loudspeakers, products such as the first “audiophile” CD player, and Meridian Lossless Packing, Meridian has been on the forefront of digital sound engineering. So when Meridian announced a new high-resolution USB DAC / headphone amp, you better believe I raised my hand, with a grin full of excitement, to ask for a review unit.

Meridian Prime Headphone Amplifier / Prime Power Supply Review

With the Explorer, Direct DAC, and now the Prime, Meridian is targeting the headphone crowd head-on with its digital expertise. I am not one to complain either, as I am a big fan of their little portable Explorer USB DAC. The Prime is a considerable step up from the portable Explorer as it can drive anything from in-ear monitors to the most taxing planar magnetics. At $2000, Meridian is asking a lot for this compact headphone amp, and that doesn’t even include the optional Power Supply Unit for $1250 that stacks below the Prime. While it won’t win a budget conscious value award, there is no denying the Meridian Prime produces a lovely neutral, yet musical sound.
